The Future of Diesel is Low CO2 Synthetic Fuels

The stew of molecules your diesel is made of has been changing. A next level technology in chemistry is enabling garbage to be transformed into hydrocarbon fuels like diesel, jet fuel, naphtha, and propane as well as other high value chemicals. These technologies enable petroleum refineries in the United States to retool themselves and move into making biofuels with the very technology used to refine modern gasoline and diesel fuels from crude oil.  Currently oil refineries take crude petroleum and crack the molecules and reform them with a hydrotreater.  This hydrogenation is what makes renewable diesel from fats, oils and greases.

If you have ever worked under your sink at home. Remember the greasy mess inside the pipes below your kitchen sink.  These renewable hydrogenation technologies can turn that trash into a super clean high performance synthetic diesel fuel.  That waste stream along with used deep fryer oil, the animal fats from rendering and other sources is the feedstock for renewable diesel.  It is exciting and this will be the future of our diesel and jet fuels.  These fuels also have a fraction of the CO2 footprint of a fossil fuel equivalent as measured by Oregon, Washington or California’s rules to measure the carbon intensity of fuels.

Diesel Fuel in Oregon and Washington

Star Oilco has been getting questions on the changes of diesel in Portland, Oregon.  If you have not noticed, many diesel pumps at retail gas stations and cardlock have seen changing stickers on the face of the fuel pumps.  As of July 1st, 2024 the City of Portland requires a minimum 15% biofuel content of all diesel sold.  This policy is called the Portland Renewable Fuel Standard.  Portland currently plans to ramp up this requirement to a 50% biofuel blend in May of 2026.  So that every gallon of diesel sold inside the City of Portland must be half biomass based diesel products blended with fossil diesel.

This has caused quite a few changes in what fuel pumps have as their fuel for sale.  Usually people notice this change with teh color of the diesel coming out of the retail nozzle.  Diesel fuel buyers are noticing the bright yellow color of B20 biodiesel, the fully clear color of Renewable Diesel or a mix of several fuels tinting the color of their diesel.  This trend is bigger than just Portland.

Today on the west coast there are a variety of product label stickers you will see on diesel pumps.  These show the variety of diesel fuel specifications that are being sold to diesel vehicles today. Blends of petroleum ultra low sulfur diesel, R99 (99%) renewable diesel, and B99 (99%) Biodiesel are combined to meet the market needs of the diesel we all buy.

This change is because of a combination of pure market forces, government rules and local decisions by fuel haulers.  Today’s diesel not only has a commodity market for the fuel it also has a market for CO2 credit value and a cap of total petroleum diesel fuel that can be sold into a west coast state with a “Cap and Investprogram requiring blends of low CO2 biofuels, the liquid fuels sold for vehicles.

Add on top of these market forces, advances in technology used to make the liquid diesel fuel.  The diesel arriving at truck stops, gas stations, cardlock or out of a hose from a bulk truck has been changing and it’s often in good ways.  Knowing how can be helpful in navigating why diesel may cost one price or another and may have a need or maintenance that another fuel does not.

THE RISE OF RENEWABLE DIESEL

Renewable diesel, also called R99 as in 99% renewable diesel, is a synthetic diesel fuel made from the same feedstock as biodiesel. The big difference though is that renewable diesel’s finished product is hydrocarbon diesel.  Biodiesel chemically is not a hydrocarbon or made up of diesel molecules.  Renewable diesel is a biofuel, but it is also chemically diesel on a molecular level. For fuel regulation they refer to it (as well as biodiesel) as “Biomass Based Diesel” for labeling at the fuel pump.

There have been billions of plant capacity brought online in the United States for renewable diesel.  During the COVID market drop in fuel prices a number of petroleum refineries shut down, then upgraded their technology to make hydrocarbon diesel fuels out of the very biobased fats, oils, and greases biodiesel is made from.  These refineries use hydrotreating technology just like they do with a crude petroleum to make an actual hydrocarbon diesel molecule.   With this technology adoption to make diesel and jet fuels from vegetable oils and animal fats billions of gallons of low CO2 diesel fuels are coming on the market and governments are requiring it’s use, such as Portland’s Renewable Fuel Standard.

THE AVAILABILITY OF BIODIESEL

The US makes billions of gallons of biodiesel.  A fuel that’s quality and performance continues to improve.  If you are not a fan of biodiesel in your fuel thinking strategically about the fuel will likely benefit your fleet operation.  The big concern with diesel fuel in a ultra low sulfur world is water and dirt suspended in the fuel affecting the performance of diesel emission systems.  With clean and drier quality specifications of B99 blend stocks today versus a decade ago the use of this fuel has grown substantially especially in the truck stop market.

When crude petroleum prices are high and therefore refined diesel prices are equally as high biodiesel is often an extremely competitive fuel.  Recently changes in Federal subsidies on biodiesel have changed this market dynamic a bit but you can presume that biodiesel will often be sold at a discount against fossil fuel diesel.  If a large seller of diesel (including petroleum refiners) can pick up pennies per gallons on millions of gallons sold they will do so.  Therefore Biodiesel is often seen in diesel in small blends even if you do not see a label on retail pump.  For blends above 5% a label is required for retail fuel sales.

Above are a variety of labels used to denote what fuel blend is coming out of a retail diesel dispenser. Feel free to call Star Oilco at 503-283-1256 if this confuses you and you want it explained.  We would be glad to do so.

These labels can be found together often at one pump.  All state and Federal standards require ultra low sulfur diesel for any on-road diesel sale.  The Federal standards also adopted by the states require a disclosure at the fuel pump if a blend is above 5% biodiesel.  The max allowable blend of biodiesel for diesel truck manufactures is a 20% blend.  If a truck dealership says that you cannot blend biodiesel up to 20% they need to take that up with the Federal Government because they need to support it.  This is why the label shows a blend may contain between 5% and 20% biodiesel content.

Renewable diesel is a hydrocarbon diesel. 

 

It is diesel meeting the ASTM D975 specification for diesel. 

Retailers selling blends of R99 in their fuel do not need to label it given this.  They still do label it given the benefits of the fuel’s performance and that customers are seeking that fuel.

Many retail places will have stacked labels showing they may be blending 5% to 20% biodiesel as well as may be adding R99 Renewable Diesel to the fuel as market conditions dictate it is the more cost competitive fuel.  When seeing a label like this it can usually be assumed they are blending a R80 (80% Renewable Diesel) and a B20 (20% Biodiesel) blend of fuel.  This blend is actually believed by some to be a higher performing fuel seeing better performance that a R99 or B20 fossil fuel blend.

Fossil fuel diesels are being replaced or blended with biomass based diesels.  Be it Renewable Diesel or Biodiesel.  These blends are driven by more than one industry requirements, government rules, or other market forces. One of these being Portland’s banned on petroleum diesel through the Renewable Fuel Standard (RFS). This is resulting in an increase of low-carbon biofuel blends that will ultimately move to a mix of 99% renewable fuel requirement by 2030.

Renewable Diesel and Biodiesel Blend fuel dispenser label.

The big drivers are industry specification for fuels (both labeling as well as chemical characteristics), state rules on selling these fuels, their quality assurance as well as CO2 content, and of course the market forces.  Market forces being the supply and demand availability of fuel needed to meet customers.  Less fuel available to sell means higher prices for customers.

A decade ago the market for diesel was far simpler. Though you had biofuels and some blend mandates basically you had a diesel specification accepted and the daily price as tracked by a lighted retailers sign, a wholesale market average or spot buying by some customers.   Today this market is far more complicated by government regulation on the west coast.  There are three big programs at state levels impacting this.

State Fuel Rules cause a unique need for one state or another. Whereas twenty years ago if Oregon or Washington fuel was selling for more than the Gulf Coast you might see brokers bring fuel into the region then driving down high prices.  With the creation of various complex and unique rules on diesel, imports of fuel to these low CO2 fuel states has dropped.  The amount of people moving product into west coast states has dropped.  The big rules causing this are the Cap and Invest programs of the West Coast states, the Low CO2 Fuel Standards of the states, and the fuel blend mandates of various jurisdictions of these states. For instance California now requires all off-road diesels but 99% renewable diesel.  Portland, Oregon also has a CO2 requirement and minimum 15% blend of biomass based diesel on all fuel sold in the state.

WHAT ARE THE DIESEL FUELS AND THEIR SPECIFICATIONS

Petroleum Diesel:
ASTM D975 Specification.

The ASTM D975 is a series of tests used to maintain consistent industry standard product performance for diesel fuel.  It includes among several tests cloud point, cold filter plug point (CFPP), several masurements of diesel fuel operability performance, intrained water content, sediment, carbon residue, ash, distillation, viscosity, sulfur, copper corrosion, cetane number, cetane index, aromaticity, and conductivity.

Renewable Diesel:
ASTM D975 Specification.

Renewable Diesel is following the same series of tests as petroleum refined diesel fuels.  It is the same ASTM D975 specification. Though Renewable Diesel has some different properties that exceed the ASTM specification of diesel.  Renewable Diesel is highly prized as a fuel because it typically is a cleaner and drier diesel fuel than petroleum diesel. This being seen by the tests on sediment and water content in a parts per million level.  Renewable Diesel content in diesel fuel can also be tested for looking for a C14 molecule (the chain typically created in a Hydrotreated Diesel process from fats, oils and greases.

Biodiesel (Methyl Esther):
ASTM D6751 Specification.

The ASTM for Biodiesel tests a mono-alkyl esters of long chain fatty acids derived from vegetable oils and animal fats. The testing for quality assurance covers an analysis for flash point, methanol, water and sediment, kinematic viscosity, sulfated ash, oxidation stability, sulfur, copper strip corrosion, cetane number, cloud point, acid number, carbon residue, total and free glycerin, phosphorus, reduce pressure distillation temperature, atmospheric equivalent temperature, combined calcium and magnesium, and combined sodium and magnesium.

For more on Biodiesel Use and Handling the National Renewable Energy Laboratory has a great book on the subject.

THE HISTORY OF DIESEL FUEL SPECIFICATIONS IN THE UNITED STATES

In the 1990’s the US EPA passed rules that demanded a phase out of sulfur in diesel fuel.  The presence of sulfur was very good for the fuel’s storage stability as well as fuel lubricity, but was horrible for air quality.   Additionally the big smog contributor was NOx (nitrous oxide) which was one of the EPA’s reason’s for pulling sulfur out of diesel.  For the EPA to get engine manufacturers to treat the NOx emissions at the tailpipe they needed all the sulfur gone (ultra low sulfur diesel) for modern diesel emission systems to be able to eliminate NOx as well as a host of other pollutants including particulates.

The story of changing diesel fuel standards in the US under the EPA is one of removing sulfur from our diesel fuel.  In 1996 the fuel refiners and sellers of diesel had to move the sulfur content of the fuel sold for on-road purposes to below a 500 parts per million standard. Commonly referred to as Low Sulfur Diesel fuel.   In 2006 the standard moved to a maximum of 15 parts per million of sulfur for all on road fuels.

In 2006 while the sulfur content of fuel was dropping the City of Portland released the first mandated blend of biodiesel content.  This being a 5% biodiesel blend.  The next year, the State of Oregon followed with its own Renewable Fuel Standard requiring this throughout the state.  This began the expectation of biodiesel in most diesel fuel in the Portland, Oregon area.  Washington also passed a similar policy for blending biodiesel but the enforcement and need for the fuel is less specific at Washington fuel pumps.

Renewable Diesel Frequently Asked Questions (FAQ)

Every Question we have been asked about Renewable Diesel

What is renewable diesel?

Renewable diesel is a synthetic diesel fuel, known for it’s lower CO2 characteristics, typically seeing purity and real world performance response superior to petroleum diesel fuel.  Renewable diesel is a next generation hydrocarbon diesel biofuel made by either the Fischer-Tropsch or Hydrogenation processes.

Hydrogenated renewable diesel is made by taking fats, oils, and greases by use of a hydro-treater.  The biomass based oil or fat is cracked and reformed in the presence of hydrogen and  catalyst forming a hydrocarbon diesel molecule.

Fischer-Tropsch renewable diesel is used by converting any btu dense feedstock (wood waste, woody biomass, municipal garbage, coal, and an endless list of low value waste products into syngas, then converting this into a wax that is reformed into hydrocarbon diesel.

Is it true that Renewable Diesel reduces CO2 emissions by more than half?

It depends on the feedstock and processes that determine the fuel pathway.  But for the most part it is safe to presume that if you use a R99 Renewable Diesel product in Oregon that it will have a lower than 50CI which would cut the CO2 emissions in half versus an equivalent gallon of gasoline used.  Sometimes Renewable Diesel can be blended with fossil fuel diesel as well as biodiesel.  Star Oilco currently presumes 99% renewable diesel is the fuel being used when describing Renewable Diesel and “cutting emissions in half” as a claim, backed up by the scientific data associated with the Oregon Clean Fuels Program and its pathways.

According to the Oregon Clean Fuels Program list of pathways for Renewable Diesel approved to be sold in Oregon shows the lowest CO2 value to be 16.36 CI and the highest to be 65CI.  Most, nearly all, of the Renewable Diesel pathways in Oregon are below 50% reduction in CO2 emissions associated with the fuel.  You can see these by reviewing the downloadable spreadsheet of “Fuel Pathways – Carbon Intensity Values” available on the left hand side of the Oregon Clean Fuels Program website under the heading “Participating Facilities” as an easy sharable link is not available.

To learn more about this please see the Oregon Department of Environmental Quality’s Clean Fuels Program page where CO2 emission pathways are disclosed for renewable fuels distributed in Oregon.  The system used to measure CO2 emissions and reduction is a modified Oregon “GREET” model.  GREET stands for Greenhouse gas, Regulated Emissions, and Energy Use in Technology. The GREET scientific system to review CO2 emissions was developed by the US Department of Energy and similar systems are used by California and Washington in their Low Carbon Fuel Standards as well.

Is HVO or Hydrogenated Vegetable Oil the same as Renewable Diesel?

Yes.  HVO is either R100 or R99 renewable diesel. The reason you will hear the phrase HVO or Hydrogenated Vegetable Oil instaed of renewable diesel is that the regulations and various incentives for renewable diesel have restrictions.  If renewable diesel is used in stationary power generation it is treated differently for the various subsidies and incentives.  The regulations on fuels for vehicles and equipment differ compared to utility scale power generation.  For this reason the power generation industry will refer to renewable diesel as “HVO” to denote it’s end use.

Is Sustainable Aviation Fuel or “SAF” the same as Renewable Diesel?

No.  Sustainable Aviation Fuel or “SAF” is a Jet A specification or a Number 1 diesel fuel. A Number 1 diesel fuel can be mixed with Number 2 without impacting it’s specification requirements.  Number 1 though cannot be mixed with Number 2 diesel weights and stay in specification.  It is a lighter end than Number 2 diesel meaning it has a different specific gravity weight of the fuel.   So in short SAF can be used as Renewable Diesel but has a much higher standard to meet than is required for Renewable Diesel. Therefore the products are very different based on this need for quality assurance to meet the aviation jet fuel specification.

There is a huge demand for Sustainable Aviation Fuel and many of the current Renewable Diesel plants in operation are upgrading their technology to make SAF.  It is expected that in the hydrotreating processes to make renewable diesel and SAF, the Jet A fuel specification is a harder one to produce.  So as the refining of SAF increases we will expect to see subgrade SAF (product made to be SAF that does not meet the standard) be moved to the Renewable Diesel market.  We will not see Renewable Diesel being used in jets though.

Can Renewable Diesel be used as Heating Oil?

Yes.  Renewable Diesel is a synthetic hydrocarbon diesel fuel.  It can be used interchangeably with petroleum diesel products of similar grade. Heating Oil is typically number 2 diesel which is the same specification as Dyed R99 Renewable Diesel (or blends of Renewable Diesel with petroleum diesel).   Star Oilco now offers R99 Heating Oil delivered in the Portland metro region area of Oregon.

Most modern oil heat appliances use a Becket Burner.  For more on heating fuel compatibility with oil furnaces and oil burning appliance please see “Alternative Fuels and Becket Burners” for more information.

Why do people use renewable diesel over petroleum diesel?

Fleet managers operating R99 Renewable Diesel report a lower mechanical cost of operation using the fuel.  Beyond the immediate benefit of R99 cutting CO2 emissions by half or more, fleets experience performance benefits from the fuel.  The big savings are seen the the performance of Tier 4 Emission systems on modern diesel seeing far less wear of the Diesel Particulate Filter system as well as far fewer regenerations of the system.  Additionally Renewable Diesel is a very clean and dry diesel fuel improving the storage stability, field operation, and general predictability of the fuel’s performance.

How do I know Renewable Diesel is being sold at a retail location?

Renewable Diesel is a hydrocarbon diesel that meets the specification for petroleum diesel known as ASTM D975 specification.  This means currently R99 can be readily blended and sold with petroleum diesel without a disclosure.  The US Federal Trade Commission and local state Weights and Measures have rules for retail pump labeling.  Blend percentages of biomass based diesel must be labeled especially if being advertised.  As R99 Renewable Diesel has a higher value and is sought out by many consumers though usually it is disclosed.  The pump labeling for R99 Renewable Diesel typically looks like the below.

R99 Renewable Diesel fuel dispenser label

What is renewable diesel made of?

Renewable diesel can be made from a host of things, usually a low value waste product. The most common feedstock used currently is waste vegetable oil, wastes from animal rendering, and other biologically derived oils. Processes using bio-oils are following a Hydrogenation process to turn low value waste oils into high value diesel and jet fuel.

Chevron Renewable Energy Group and Diamond Green Diesel (Diamond Green is in a joint venture with Valero) are the largest producer of renewable diesel with their REG Ultra Clean Diesel product in the United States. Neste is the largest producer of renewable diesel internationally, with its “Neste My” product.  being the two largest producers of low CO2 bio-oil derived renewable diesel fuels.

Major petroleum refiners have also turned around existing petroleum refineries into Renewable Diesel Refineries to produce this in demand low CO2 fuel. HF Sinclair , Marathon, Phillips 66, and Montana Renewables. There are quite a few newer Renewable Diesel projects planned and in progress around the United States as well as in the Pacific Northwest.

Other refiners of renewable diesel (on a much smaller scale of production) are using a Fischer-Tropsch process with wood waste, sorted higher grade municipal garbage, and other high btu value carbon based waste products.  Many expect this to technology to be the future of all diesel and jet fuel refining turning refuse into fungible low carbon fuel.

What is renewable hydrocarbon diesel?

Renewable hydrocarbon diesel is a synthetic diesel fuel made from non-petroleum feedstocks like vegetable oil, animal fats, municipal waste, agricultural biomass, and woody biomass. It is characterized by having a low CO2 and renewable resource for its feedstock and is made without crude petroleum, coal, or natural gas as a direct feedstock input in the refining process.

How do they make renewable diesel?

Renewable diesel is made by several processes. If you are buying renewable diesel, it is probably from a Hydrogenation process used by Renewable Energy Group and Neste for their products. Other smaller volume producers are using a Fischer-Tropsch process or Fast Pyrolysis. Both processes involve taking energy dense molecules, cracking those molecules under heat and pressure, then reforming them in the presence of a catalyst and added hydrogen, which forms a renewable diesel molecule.

Is renewable diesel a lower carbon fuel compared to petroleum diesel?

Yes, to this point all renewable diesel made from renewable feedstocks have appeared to be a lower CO2 fuel compared to petroleum diesels. The California Air Research Board in particular has done research on this in depth.

The low CO2 lifecycle emissions of Renewable Diesel also is tracked closely and supervised by California’s Low Carbon Fuel Standard, Washington’s Low Carbon Fuel Standard, and Oregon’s Clean Fuels Program. The highest value markets for low CO2 fuels in the United States are California and Oregon, which both have mechanisms that track and price the CO2 intensity of diesel fuels as well as the sustainable lower CO2 substitutes and blend-stocks that can go in those diesels. They track, rate, and determine the carbon intensity of the fuels providing a neutral and scientifically defensible number for CO2 reduction.

Is renewable diesel available in Oregon?

Renewable diesel is readily available for delivery from Star Oilco throughout the Pacific Northwest via 10,000 gallon volumes of bulk delivery.   Star Oilco is also offering bulk delivery of any size and mobile onsite fueling service within 100 miles of the Portland, Oregon market.

Star Oilco has R99 Renewable Diesel available with a Star Oilco CFN Cardlock card in Portland, Oregon.

What is the difference between biodiesel and renewable diesel?

Biodiesel and renewable diesel are very different fuels made with very different processes. In a nutshell, biodiesel is made with a simple chemical reaction that turns vegetable and animal fats into fuel. Renewable diesel is made from far more complicated process where vegetable and animal fats (as well as other feedstocks) are cracked on a molecular level and built back into synthetic diesel fuel.

What is the difference between renewable diesel and Sustainable Aviation Fuel?

The difference between the fuels is the specific gravity and general specification for what the fuel is used for. Jet fuel, or Sustainable Aviation Fuel, and on-road diesel fuel are different fuels and therefore have different specifications. Renewable diesel is typically referring to a #2 diesel specification for on road diesel use.

Sustainable Aviation Fuel or “SAF” is typically referring to “Jet A” or “JP8” jet fuel specification for fuel. This is a #1 diesel range fuel with use and handling requirements that are far more stringent than for on-road or off-road diesel fuels. Renewable jet fuel can be used as a kerosene or #1 diesel fuel but renewable diesel cannot be used as a jet fuel.

Where do I buy renewable diesel in Oregon or Washington?

Renewable Diesel is currently available for bulk delivery and mobile onsite fueling. It will soon be offered at commercial cardlock in the Portland area. It is being sold as R99 and as Ultra Clean Diesel, which is a mixture of biodiesel, renewable diesel, and petroleum diesel.

What is R99?

R99 stands for 99% renewable diesel and 1% petroleum diesel.  Federal rules over alternative diesel fuels made fuels requires that manufacturers of non-petroleum derived diesel fuels must blend a minimum 1% petroleum with the fuel to generate a Renewable Industry Number or “RIN” under the US Federal Renewable Fuel Standard. Additionally there are other incentives that require a “blender of record” to receive these tax credits.

Is renewable diesel being made in Oregon?

As of Spring 2022, renewable diesel is not being manufactured in Oregon. There is a major projects underway, Next Renewable Fuels in Port Westward, Oregon.

What is renewable diesel made from?

Renewable diesel can be made from many energy dense carbon based material.  By volume of produced product sold in the United States, vegetable oils and animal fat-based wastes are the most common feedstock. Woody biomass, agricultural wastes, and sorted municipal wastes are also sources for renewable diesel production.

Is renewable diesel made from palm oil?

Palm oil can be used as a feedstock for renewable diesel. There are producers who use palm oil as a feedstock. In the United States, feedstocks and carbon intensity are tracked closely under both Oregon and California’s fuel programs.  You can determine if a supplier is using palm oil as a feedstock through these regulated pathways.

How much does renewable diesel cost?

This is a tough question to answer given there are several markets intersecting.  From the feedstocks to the market demand for the finished product as well as both California and Oregon’s Clean Fuel Standards which place a price on the CO2 intensity of the fuel which reduces the cost of the fuel if consumed in Oregon and California.

It has consistently been trending between the same cost and over $1 a gallon higher than petroleum diesel depending on the state, you buy renewable diesel in. In California, renewable diesel is very close to petroleum diesel depending on the value of CO2 credits for lower-carbon fuels. In Oregon, it has consistently been between $.05 to $.80 a gallon higher than diesel also depending on the value of CO2 abatement associated with the fuel and what these carbon credits are trading for.

When petroleum diesel costs are high Renewable Diesel tends to be more competitive with petroleum diesel.  When petroleum diesel is below $3 a gallon the cost of Renewable Diesel by comparison is usually higher unless CO2 credits are in higher than normal demand for Clean Fuels Program demands.

Can you mix petroleum diesel and renewable diesel?

Yes. Renewable diesel and petroleum diesel can be blended in any mixture without worry. They are drop-in substitutes for each other in your fleet’s use.  Renewable Diesel is a drop-in fuel. It is a hydrocarbon diesel that will work mixed with diesel or biodiesel blends of petroleum diesel.

What Are Our Options for Alternative Fuels?

What are our options for alternative fuel?

Biofuels are eco-friendly fuel choices because they are made from renewable resources and produce fewer emissions than fossil fuels. Biofuels and biodiesel can also be used to improve air quality. They also allow us to reduce the dependence we have on using fossil fuels. 

Biofuels are liquid fuels produced from biomass, which is organic matter such as plants, algae, and agricultural waste. Biofuels can be used to power vehicles, generate electricity, and heat homes and businessesBiofuels are renewable and can reduce emissions of greenhouse gases. They provide an alternative to fossil fuels and help to conserve natural resources. Reducing the emissions of greenhouse gases is an important factor in helping to combat climate change. Biofuels have the potential to be a significant part of the solution. Biofuels can reduce emissions of greenhouse gases by replacing fossil fuels, which are made from non-renewable sources. Using biofuels instead of fossil fuels can also help to reduce air pollution. 

Some common types of biofuels include: 

Ethanol

Ethanol is a type of alcohol that is made from fermented corn, sugarcane, and other crops. It is blended with gasoline to create E85, a fuel that can be used in flexible-fuel vehiclesThis type of fuel is cheaper than regular gasoline, and it is more environmentally friendly. It is also safer to store and transport than other types of fuel. The benefits of using ethanol fuel include reduced emissions of carbon dioxide, improved air quality, and increased energy security. It is also renewable and biodegradable, making it a more sustainable fuel choice. Additionally, the production and use of ethanol fuel can create jobs and support local economies. 

 

Biodiesel

Biodiesel is a type of diesel fuel that is made from vegetable oils, animal fats, and waste grease. It can be used in unmodified diesel engines as a drop-in solution. It is a renewable fuel and emits less carbon dioxide than petroleum-based diesel. Biodiesel is also less toxic and it’s biodegradable. The benefits of biodiesel include reduced emissions of carbon dioxide, sulfur dioxide, carbon monoxide, and unburned hydrocarbons; improved combustion efficiency and power output; improved lubricity; and improved fuel economy. Additionally, biodiesel is biodegradable and has a lower energy content than petroleum-based diesel, making it safer to handle and transport in the Portland, Oregon metro area as well as Vancouver, Washington. 

Biodiesel can be used in a variety of applications, including transportation, heating and electricity. Biodiesel is used in transportation to power diesel engines in cars, trucks, buses, and other vehicles. Biodiesel can also be used to heat homes and businesses. Biodiesel also can generate electricity in power plants.  

Biodiesel is a promising alternative to petroleum diesel, and its use is growing around the world. The United States is the world’s largest producer of biodiesel. 

Algae-based biofuels

Algae-based biofuels are a new type of biofuel that is made from algae. Algae are a rapidly renewable resource that can be grown in a variety of environments. Algae is a group of photosynthetic organisms that grow in water. Algae have the potential to produce significantly more oil than traditional biofuel crops, such as corn and soybeans, and they can be grown on non-arable land, such as saltwater or wastewater. This makes algae an attractive potential source of renewable fuel. 

When algae are grown in the right conditions, they can produce up to 77% oil, which can be converted into biodiesel, renewable diesel, or other biofuels such as ethanol, butanol and jet fuel. Algae-based biofuels have the potential to significantly reduce greenhouse gas emissions from transportation, electricity generation, and other industries. However, there are still challenges that need to be overcome before algae-based biofuels can be commercially viable. These challenges include scalable production, costs, efficient harvesting and efficient processing to extract the oil. There is a lot of research and development underway to overcome these challenges and with continued investment, algae-based biofuels have the potential to become a major source of renewable fuel in the future. 

 

Hydrogen

Hydrogen is a versatile energy carrier that has the potential to play a significant role in the transition to a clean energy future. It is the most abundant element in the universe and can be produced from a variety of sources, including natural gas, biomass, and renewable electricity. When used in a fuel cell, hydrogen produces only water and heat, making it a clean and efficient fuel source. 

Using hydrogen as a fuel provides clean burning, a high energy density, efficiency, among many other benefits. Hydrogen doesn’t produce any emissions of harmful pollutants which makes it an attractive option as a fossil fuel alternative. Hydrogen’s high energy density means that a relatively small amount of hydrogen can provide a lot of energy. Using hydrogen fuel cells to generate electricity are 2-3 times more efficient than internal combustion engines. It can also be used in a wide range of applications, including transportation, electricity generation as well as industrial processes.  

Some of the challenges we face with hydrogen as a fuel are its current methods of production. They are not always as clean or sustainable currently. Storing hydrogen, being a gas, requires specialized storage tanks. The infrastructure for transporting and distributing hydrogen is not yet fully developed.  

Overall, there is a growing interest in using hydrogen as a fuel source with very promising results and possibilities in our future. Governments and businesses all over the world have been investing in research and development to figure out solutions to these challenges in order to make hydrogen a more viable energy source.  

Renewable Diesel

Renewable diesel can also be known as hydro-treated vegetable oil (HVO) or green diesel, and is a type of biofuel that is chemically identical to petroleum diesel. It is produced from a variety of feedstocks, including vegetable oils, animal fats, and waste oils. Renewable diesel can be used in any diesel engine without modification, and it offers a number of environmental benefits over petroleum diesel, including: 

 

Reduced greenhouse gas emissions 

Renewable diesel (R99) reduces greenhouse gas emissions by up to 90% compared to petroleum diesel. R99 being cleaner and more efficient, makes it an attractive option for many transportation companies. 

 

Improved air quality 

Renewable diesel produces fewer harmful pollutants, such as particulate matter and sulfur oxides, than petroleum diesel. Additionally, renewable diesel is lower in carbon than petroleum diesel, making it a more sustainable option for transportation. Renewable diesel is also more efficient, reducing the amount of energy needed to produce the same amount of fuel. 

 

Biodegradability  

Renewable diesel is biodegradable, meaning that it breaks down naturally in the environment.  This helps to reduce the amount of harmful pollutants in the environment. Renewable diesel also reduces emissions of carbon dioxide, a major contributor to climate change. 

Renewable diesel is a promising alternative to petroleum diesel, and its use is growing around the world. The United States is the world’s largest producer of renewable diesel, and the European Union has a mandate to use 10% renewable diesel by 2030.  

Even more of the benefits of using renewable diesel:  

The use of renewable diesel helps reduce our dependence on fossil fuels since it is a renewable fuel.  

The local economy can be supported by renewable diesel, which is often produced from local crops.  

A number of sectors, including agriculture, manufacturing, and transportation, create jobs in the renewable diesel industry.  

Ultimately, renewable diesel is a clean and sustainable fuel that offers environmental and economic benefits. Around the world, its use is growing as an alternative to petroleum diesel. Renewable diesel helps to reduce air pollution, reduce greenhouse gas emissions, and reduce dependence on foreign oil. It is also a renewable and sustainable fuel source that can be used to produce electricity. As such, renewable diesel is an important option for reducing carbon emissions and improving sustainability overall. 

When we look at the variety of renewable and biofuel opportunities, there are a variety of ways that we can reduce our carbon footprint today without any modifications to our current engines.

Why diesel fuel in Oregon may go up in 2025

What are the market forces impacting diesel in Oregon for 2025?

There are some big changes coming for diesel fuel in Oregon and it is not widely reported. The biggest likely change being a smaller supply of renewable diesel in the first quarter of 2025.  Renewable Diesel is expected to see a shorter supply than in recent years as imports drop off with the removal of subsidies.

Oregon is going to see several major market forces impacting the wholesale, as well as retail cost of diesel to those that buy it.   To list them simply, the following events will converge on New Years Eve:
The end of the $1 a gallon US Blenders Tax Credit (BTC) subsidy on biodiesel and renewable diesel.
– The subsidy replacing the BTC, the Producers Tax Credit (PTC), blocks imported biofuels such as Neste Renewable Diesel.
– Oregon is relaunching its Climate Protection Program which will cap the market allowance for fossil fuels.
Portland has a Renewable Fuels Program that requires the blending of Biodiesel and Renewable Diesel under a 60% reduction in CO2 emissions from petroleum diesel (biofuels sold in Portland must be below a 40CI under Oregon’s Clean Fuels Program).
California has mandates for Renewable Diesel in many uses raising the cost of R99 renewable diesel throughout the US.

These forces will raise the cost of fossil fuel diesel, renewable diesel and biodiesel while at the same time Oregon and Portland are requiring the use of these biofuels.  This will mean a higher retail and wholesale price inside Oregon compared to the rest of the United States. We cover the details of these trends below in depth.

THE OREGON CLIMATE PROTECTION PROGRAM

The biggest change impacting the price for on-road diesel is the return of Oregon’s Climate Protection Program (CPP). The program’s more common name is Cap and Invest, in fuel pricing it is referred to as “Cap at the Rack” as its allowance requirements are priced on a gallon of fossil fuel.  The program caps the total fossil fuel allowed to be sold inside Oregon. Then, revenue generated from selling the allowances to import CO2 contributing fossil fuels into the state, is invested to reduce future needs for these fuels.  In 2025, this program will return and fuel importers into the state of Oregon will have to capture the cost of reducing their CO2 emissions under this program.

Oregon previously had a “Cap and Invest” program limiting the total market share allowed for petroleum diesel fuels.  This created a higher cost for diesel fuels refined from petroleum compared to renewable diesel and biodiesel. This program was stopped by an Oregon court decision in 2023. The Oregon Department of Environmental Quality (DEQ) just finished and published the new rules for this program correcting the issues the court had with the program.

The way the Oregon Cap and Invest works on the market is similar to musical chairs. If you imagine the market for diesel is limited just like seats in musical chairs, every year they will take a few of the fossil fuel chairs away.  That means that anyone maintaining their existing customer gallons or trying to grow their volumes must meet this demand with renewable diesel, biodiesel or some other fuel.  The limited market for fossil fuels is represented by “Allowances” provided by the Oregon DEQ.  If a fuel seller cannot reduce their fossil fuel dependency, they need to buy a CPP Allowance in an Oregon DEQ curated market for them.

The value of these CPP Allowances is actually charged on each gallon of fuel sold by the regulated parties.  It is commonly called “Cap at the Rack” and can range in cost from nothing to over $.50 a gallon depending on how hard it is to meet the need of the program.  The biggest impact on the Cap at the Rack cost is how much renewable diesel or biodiesel is being used by those selling fuel.   Prior to the stoppage of Oregon’s CPP program, the Cap at the Rack cost usually ran around $.05 to $.30 a gallon.  It is expected we will see a return to this cost starting January 1st, 2025.  OPIS reports have an adjusted and non-adjusted option to capture the cost of this program.

The way the CPP program is designed is that if a fuel seller brings in a lower CO2 fuel like renewable diesel or biodiesel into the state of Oregon those gallons do not count towards the fossil fuel market cap.  So a R99 seller has no CPP Allowance obligations for those gallons.  A B20 biodiesel blender, as well, picks up 20% more gallons available to sell as those biodiesel gallons do not count against their CPP Allowances.  This facet of the CPP is why the market of renewable diesel in particular is a big deal for diesel prices.

The intent of Oregon is for consumers, fleets, farmers, municipalities, and industry in Oregon to grow their energy needs, they will need to use more low carbon energy.  If this energy use is a fleet running over 32,000 GVW this will mean low CO2 biomass based diesel fuels.   At the same time, the CPP program is kick-starting back into existence, the world of these biofuels is seeing some major market changes.

OREGON CLEAN FUELS PROGRAM

Oregon has another program to reduce the CO2 of the liquid fuels sold inside the state.  This program is additional and works in conjunction with the CPP.  It is the Clean Fuels Program (CFP) and is extremely similar to the California Low Carbon Fuel Standard (LCFS).  This program creates a market for Carbon Credits that are traded and required by fuel importers into Oregon.  OPIS also shows this program’s cost per gallon on their reporters.

Where the Climate Protection Program is like musical chairs with market share as the allowed market for fossil fuel shrinks year over year, the Clean Fuels Program is like a coupon required with sales of fossil fuel.  The major importers of fossil fuels into Oregon must show they are blending lower CO2 biofuels by presenting CO2 credit generated under the CFP program.  Users of fuel inside Oregon also see a benefit for bringing in low CO2 fuels when the market needs the credits so that voluntary users of high blend biofuels like R99, B99, B20 or E85 (85% ethanol) get financial support via a reduced final cost per gallon if using those fuels.

The reason we see renewable diesel in Oregon compared to the rest of the United States is because of this program.  This value of a Carbon Credit is usually taken to buy down the competitive price of these biofuels.  The concept is that if a fuel importer is bringing low CO2 fuels into Oregon, the reduction in CO2 these fuels represent can generate a CO2 credit.  That credit being sold on an open market to help reduce the cost of a low CO2 fuel compared to a fossil fuel.  The market for these credits is banked and has been building for years. Currently, the CO2 value is low as there are plenty of credits.

If the market availability of renewable diesel and biodiesel is dropping, the value of these credits should be rising.  The overall market will be bearing this cost though consumers will likely never see it.  In effect these regulatory market impacts of less renewable diesel in Oregon will mean a higher Carbon Credit price under the CFP program.  That will help lower the blended or delivered costs of B99 biodiesel and R99 renewable diesel hitting the end consumer.

RENEWABLE DIESEL AND BIODIESEL SUPPLY IN OREGON

Biodiesel and renewable diesel are called “Biomass Based Diesel” as a respective class of biofuels.  Where fossil fuel diesel is made from crude petroleum, biomass based diesels are diesel fuels made by several technologies from biomass feedstocks. The most widely used feedstock being fats, oils, and greases from virgin vegetable seed oils (soy and canola) or waste streams like recycled deep fryer oils, meat processors rendering fats, recovered trap greases, and many other sources of fat waste streams.

The 2025 Oregon Fuels Forecast for Oregon predicts a 199+ million gallon need for R99

The Oregon Department of Administrative Services Office of Economic Analysis produces a Clean Fuels Forecast which describes the size of the market need in Oregon.  In 2023, Oregon used 133.3 million gallons of R99 inside the state. The fossil fuel diesel used in 2023 was 577.6  million gallons by comparison.  So R99 and B99 blended with those gallons is a substantial 26% of the diesel burned in Oregon by the most recent total data.  The forecast for 2024 Renewable Diesel is 46.6 million gallons of R99, which appears to be exceeded by quite a bit.

We do not have total consumption numbers for 2024 yet, but we do know thanks to the US Energy Information Agency, that imported R99 from Neste Singapore by itself through October was roughly 62 million gallons rounding up.  The Oregon Clean Fuels Forecast expects 199.5 million gallons of renewable diesel in 2025.  As the program ramps up with this expectation, the imports of previous years will be far less competitive without subsidies.  This means the price of renewable diesel will be higher, unless US production scales to not only fill this market void but also add tens of millions of gallons into the state.

Of that 133.3 million gallons of R99 used in 2023 in Oregon, a third, more than 40 million gallons of it was imported Neste Renewable Diesel.  973,000 barrels of renewable diesel was shipped from Singapore to Oregon that year.  Other renewable diesel refiners such as Diamond Green, HF Sinclair, Marathon, Montana Renewables, Phillips 66 and Chevron also had R99 product sold into Oregon.  Regardless of the expansion of US domestic Renewable Diesel production in recent years, the Neste product no longer receiving subsidies will have a real impact to maintain these 133+ million gallons of R99 inside Oregon.

This same projection reports that Oregon’s B99 Biodiesel use inside the state in 2023 was 78.8 million gallons.  With a projection of Biodiesel to rise 83.8 million gallons in 2025.  Given these market needs, Star Oilco predicts R99 to be expensive compared to petroleum diesel. Biodiesel will be more competitive given the available product and no substantial change in suppliers.  Biodiesel will also need to be used to replace R99 gallons under the CO2 reduction programs of Oregon. Due to these market forces Star Oilco has contracts for supply at reasonable prices for our existing customers.

R99 is mandated in certain diesel uses in California by the California Air Resource Board (CARB) which make for an inelastic price.  Diesel equipment operators in California will have to buy R99 at any price.  This will raise the prices we in Oregon can expect to see renewable diesel at.  The other low CO2 diesel fuel biodiesel will not be impacted by CARB the same way and we can expect to see B20 become more widely sold because of its more competitive price.

Biodiesel has a much more widely used market development around the US, especially in over-the-road trucking.  The plants that make biodiesel also tend to be co-located, owned in collaboration with feedstock producers, and integrated within the Soy industry that produces the feedstock.  Expect that biodiesel will continue to be more competitive with diesel than renewable diesel if price is the concern.

It is worth mentioning that the CARB mandates for R99 use in California will have impact to set the price for renewable diesel in other states.  If the market demand mandated by CARB continues and the market is short, the price can be expected to rise to meet this demand.  So unsubsidized imported R99 will likely continue to flow into California and other states but it will be at a full cost to make up the subsidy.  This will likely mean that incremental gallons of R99 needed to meet the market growth projected in Oregon will be at a premium over Oregon diesel to match California’s diesel market.

US BLENDERS TAX CREDIT EXPIRATION IMPACTING OREGON

The biggest unknown on how expensive diesel will be for Oregonians relates to Federal biofuel policy.  For the last twenty years the US Government has had an on-again/off-again subsidy on biodiesel and more recently renewable diesel.  There have been years the subsidy was not renewed which informs us of what probably will happen with prices on biodiesel.  Renewable diesel though is a stickier market.  The reaction of R99 renewable diesel prices in California, Washington and Oregon market is the big question and it comes down to an issue of production.  Two big issues at play are how much renewable diesel will these states continue to see from Neste’s Singapore plant and how much new US production for renewable diesel comes online to feed the market need.

The Blenders Tax Credit will be replaced with the Producers Tax Credit

The Blenders Tax Credit expired December 31st.  There are those that hope that in January the new Congress will take up an extension of this but most experts in the industry do not expect and are not betting an extension will not occur.  Meanwhile there is subsidy regime named the “Clean Fuels Production Credit” or the slang term preferred by industry the Producers Tax Credit (PTC) which ranges from $.20 a gallon to $.80 a gallon depending on how low CO2 the fuel as well as some labor practices.  The PTC also bars imported renewable diesel and biodiesels from getting any money at import.  Approximately more than 40,000,000 gallons a month of renewable diesel flows from Neste Singapore to the west coast, this will have a huge impact on Oregon.  For those accustomed to that fuel at the same price as fossil fuel diesel, the expiration of this subsidy will raise our prices for those demanding R99 renewable diesel which was already in short supply prior to this change.

There is also another wrinkle in the subsidy policy of the US with this.  The subsidy on Sustainable Aviation Fuel (SAF), basically renewable diesel meeting the Jet A fuel specification, is still in place for imported product for another year.  Europe also has some significant incentives and mandates for SAF.  Renewable diesel refiners, both domestic as well as foreign have a huge financial incentive to make renewable jet fuel over renewable diesel. This reality probably means that if a gallon of fuel can go to a jet fuel market over a transportation market it will.

So the market forces for renewable diesel in particular probably means less R99 available nationwide in the US.  While that is happening, the state of California has mandated that all off road equipment run R99 Renewable Diesel.  So regardless of what the price of this fuel is, California will have to use it in huge volumes.  Markets being what they are, for high volume fleets demanding R99 they can expect the R99 price in Oregon will track the price paid in California.  There will be exceptions of contract relationships for supply of R99 as well as retail brands moving renewable diesel blends to meet their strategic CPP requirements.  This will definitely mean anyone wanting R99 will want to line up a contractual supply agreement or can expect a higher price than in 2024.

THE FEDERAL RFS AND RINS

It should also be mentioned that the US EPA has a Renewable Fuel Standard of its own. It is a completely different regulatory system compared to the Portland RFS.  This program requires gasoline refiners as well as importers to use so much biofuel in their sales inside the United States.  Federally refiners and importers must prove they blended specifically assigned amounts of ethanol, and biomass based diesel fuels.

This program attaches a Renewable Industry Number (RIN) on every gallon of biofuel sold in the US.  As there are many unobligated users of this biofuel in the US those blending their own biodiesel, renewable diesel and ethanol generate RINs that can be sold to the refiners and importers of gasoline inside the US.

The RIN value has been low compared to historic values for biomass based diesels.  As Biodiesel and Renewable Diesel generate the same type of RIN, the reduction in imported R99 might raise the value of these RINs.  This value increase for the Renewable Industry Number is expected to slightly off set the hard subsidy.  It will be a market based value so it can not be relied upon for lowering the cost of biofuels, but can be expected to help with price.

As more US produced renewable diesel is coming online, hopefully enough to replace the lost imported gallons before the busy summer diesel season, these RIN values may not have a major contribution to the wholesale price of R99.

CONCLUSION

We predict diesel prices to rise in Oregon compared to the US in the first quarter of 2025

Star Oilco’s team saw these market conditions coming during the summer of 2024.  We have locked in contractual supply of R99 renewable diesel for our existing customers and have additional supply for customers seeking R99 renewable diesel by Star Oilco owned cardlock sites, mobile onsite fueling or smaller volume bulk delivery.

Star Oilco expects a Cap at the Rack price from the Oregon CPP to be between $.10 and $.40 a gallon by the end of January depending on biofuel supply. With unofficial conversational predictions with several large fossil fuel refiners and brokers, there is an expectation of over $.25 a gallon as a Cap at the Rack price.  We think it will be higher than that with the removal of millions of gallons of R99 from Oregon’s market.  In the first quarter with the removal of imported R99 hitting the state we expect the Cap at the Rack price to start in the higher $.30 a gallon range where it left off when the program was ended by a court. As the low CO2 exempt renewable diesel gallons shrink in the first quarter a heavier reliance on fossil diesel will be required.

We expect quite a bit of biodiesel to be loaded up ahead of the $1 a gallon subsidy being ended on December 31st.  Renewable diesel will be in short supply due to disruptions in supply of imported product.  So first quarter R99 will be at a premium and B99 for blending with diesel will be a deal to be had as fossil fuel diesel prices rise.  Expect to see far more B10 and B20 offered in the market place as either a more common than not fuel at retail gas stations, truck stops, and most cardlock stations, especially in Portland.  Star Oilco will have options for our customers of either B20, R99, or R20 blends of diesel all complying with the City of Portland Renewable Fuel Standard inside the city.  Star Oilco’s Portland CFN and Pacific Pride locations will have both R99 and B20 hoses available for customers.

California will continue to demand any and all R99.  If the market is short R99 because of a removal of imported renewable diesel, the value of R99 in California will rise to justify foreign R99 to enter the market without a subsidy.  Star Oilco presumes that number will be between $.40 to $.80 a gallon.  If R99 in California is able to demand a premium, Oregon will have to pay that price for incremental gallons.  Oregon has a specific need for R99 and B99 for retail gasoline sellers to meet the Climate Protection Program (if you sell so much gasoline you must reduce your market share someplace and R99 diesel is the easiest way to do that).  Oregon retailers will be seeking to move a budgeted amount of renewable diesel and biodiesel to meet their fossil fuel allowance budgets under the CPP.  Each gallon beyond that will have to compete with California at a high price.

R99 will still be available but we expect incremental gallons to be at a premium.  Contractual gallons direct with a refiner of renewable diesel will have a consistent price that a business can manage fuel surcharges against diesel.  Outside of a contract for volumes, the wholesale rack price of R99 may vary wildly compared to a B5 ULSD fossil fuel diesel prices depending on how high diesel is going for are as well as the CPP and CFP values of a Carbon Credit and Cap at the Rack.

The big unknown to price is how one key importer of R99 will respond to the market without a subsidy.  It is the assumption of Star Oilco that California will continue to buy imported R99 without a subsidy for it’s off-road mandated market. If the economics of Neste are such, they can compete and open the floodgates of R99 and this could change.  This open flood of product is not expected especially given the economics of Sustainable Aviation Fuel which renewable diesel plants are expected to make more of in 2025.

The Oregon and Washington market will see a flow of new capacity of R99 for retailers mandated to reduce their fossil fuel volumes.  US production of R99 is expected to more than compensate by 2026, but 2025 will be a chasm to jump.  Chevron, HF Sinclair, Marathon, and Phillips 66 will be procuring and supplying US made biomass based diesel to the Pacific NW for their retail gas station needs.  We would expect to see R99 or blends of it sold at parity with branded diesel in the retail market in Oregon.

Commercial sellers of wholesale unbranded diesel will have a tougher time lining up R99 at a price in line with wholesale B5 or B20 ULSD.  No doubt with these higher prices we will be seeing an evolution of R20 (20% renewable diesel) as well as blends of biodiesel with renewable diesel available inside the City of Portland for it’s Renewable Fuel Standard as a premium fuel at a competitive price with diesel.

Star Oilco has R99 and R20 blends for commercial customers in the Portland, Oregon area.  We also have R99 available for Clark County Washington commercial and municipal fleets.  Star Oilco also has biodiesel blends and can support fleets seeking to succeed with it.  Call us if you would like to talk about your fuel supply in 2025.

If your fleet has an interest in a consistent and contractual supply of R99 renewable diesel or wants to develop a relationship that prioritizes a 20% of renewable diesel blended to meet Portland’s Renewable Fuel Standard compliance please feel free to reach out to Star Oilco.

Renewable Diesel vs Biodiesel for Heavy-Duty Trucks

The Fuel Revolution

In the realm of sustainable energy, the race for cleaner and more efficient fuels is a top of mind priority for the majority of the industry. As heavy-duty trucks continue to dominate our highways and play a pivotal role in transporting goods across the country, the choice of fuel is paramount. The two most common fuels used throughout the PNW for greener transportation are: Renewable Diesel and Biodiesel. In this blog, we’ll take a deeper look into the power generation of these fuels, highlighting the key differences between them and citing relevant studies that illuminate their qualities.

Renewable Diesel: The New Age Wonder Fuel 

Renewable Diesel, often referred to as “green diesel,” or R99 is a high-quality alternative fuel that shares many characteristics with traditional diesel. However, it is derived from renewable feedstocks, such as vegetable oils, animal fats, and waste greases, through a process called hydrotreating. This process not only produces a cleaner-burning fuel but also eliminates impurities and aromatics found in traditional diesel. The result is a fuel with significantly lower emissions and enhanced performance. 

Lower Emissions:

Perhaps the most significant advantage of renewable diesel is its environmental footprint. Studies, like the one conducted by the National Renewable Energy Laboratory (NREL), have shown that renewable diesel can reduce greenhouse gas emissions by up to 80% compared to standard diesel. This drastic reduction in emissions makes it a vital fuel in the efforts to combat climate change. 

Better Fuel Economy:

Renewable diesel boasts a higher energy content than biodiesel, allowing vehicles to travel more miles per gallon. A study by the California Air Resources Board (CARB) demonstrated that renewable diesel can improve fuel efficiency by 5-7% compared to biodiesel. For the trucking industry, this translates to significant cost savings. 

Compatibility:

One of the standout features of renewable diesel is its compatibility with existing diesel engines and infrastructure. Heavy-duty trucks can make the switch to renewable diesel seamlessly, without requiring any engine modifications or special storage facilities. 

Reduced Maintenance:

Studies like the one from the University of California, Riverside, have indicated that renewable diesel can lead to reduced engine wear and lower maintenance costs. The fuel’s superior lubricity and cleaner combustion help extend the lifespan of engine components. 

In 2015, NREL ran a study in partnership with the UPS and the Clean Cities Coilation to compare the fuel economy and overall impact of renewable diesel compared to petrelem diesel in 12 USP delivery vehicles operating out of Houston. The results of this study were that renewable diesel reduced carbon emissions by 4.2% comparatively to petroleum diesel. This finding is a result of the properties of renewable diesel given its higher mass-based heating value and lower carbon-hydrogen ratio. 

The UPS is one of the largest user of renewable diesel in the world. In 2015 UPS announced their plans to purchase over 40 million gallons of the sustainable fuel over the next three years (2015-2018). UPS was supplied this renewable diesel by Solazyme (now known as TerraVia).  

Below is a breakdown of the vehicles used in the study.

BIODIESEL

Biodiesel, often derived from vegetable oils or animal fats through a process called transesterification, has been around for a while and has made significant strides in reducing emissions compared to traditional diesel. However, when pitted against renewable diesel, there are some critical differences.

The Limitations of Standard Biodiesel

Emissions:

While biodiesel is undoubtedly cleaner than traditional diesel, studies like the one published in the Journal of Environmental Science and Technology show that its greenhouse gas reduction potential is not as remarkable as that of renewable diesel. The production process of biodiesel also consumes substantial energy, offsetting some of its environmental benefits. 

Performance:

Biodiesel’s energy content is lower than that of renewable diesel, resulting in decreased fuel efficiency. Research from the University of Nevada, Reno, indicates that biodiesel can lead to a 3-10% reduction in fuel economy compared to renewable diesel. 

Cold Weather Performance:

Biodiesel has a higher cloud point and gel point than renewable diesel, making it less suitable for cold-weather operations. Trucks operating in regions with harsh winters may encounter issues with fuel gelling, potentially causing operational disruptions. 

Compatibility Challenges:

Biodiesel’s higher viscosity can lead to filter plugging and injector coking in some older diesel engines. This issue necessitates additional maintenance and potentially costly modifications.

The Road Ahead: Renewable Diesel’s Triumph 

In the comparison of Renewable Diesel vs. petroleum diese for heavy-duty trucks, renewable diesel emerges as the clear winner. Its lower emissions, superior fuel economy, compatibility with existing infrastructure, and reduced maintenance requirements make it a game-changer in the transportation industry’s quest for sustainability. 

Studies across the board indicate that renewable diesel outperforms standard biodiesel in terms of environmental benefits and cost savings. For heavy-duty truck operators looking to reduce their carbon footprint and improve their bottom line, renewable diesel is undoubtedly the fuel of the future. 

In the quest for a greener future, renewable diesel has firmly taken the lead. Its remarkable reduction in emissions, better fuel economy, and seamless integration into existing diesel infrastructure make it the go-to choice for heavy-duty truck operators. While standard biodiesel has made commendable progress in reducing emissions, renewable diesel emerges as the winner in the arena of cleaner and more efficient fuels. 

The studies quoted in this blog are just the tip of the iceberg, illustrating the overwhelming evidence in favor of renewable diesel. As we move forward in our pursuit of sustainable transportation, it’s clear that renewable diesel will play a pivotal role in driving us toward a cleaner, more environmentally friendly tomorrow.

Understanding the Benefits of Renewable Diesel

In an era of environmental consciousness and sustainable alternatives, the need for renewable energy sources has become increasingly evident. One of the notable contenders in this field is renewable diesel —a clean-burning, low-emission fuel that could revolutionize the transportation sector. We will dive into renewable diesel, exploring its production process, environmental benefits, and potential to replace petroleum-based diesel. 

What is renewable diesel? Renewable diesel, also known as green diesel or second-generation biodiesel, is a next-generation alternative fuel derived from sustainable feedstocks such as vegetable oils, animal fats, and waste fats and oils. Unlike traditional biodiesel, which is typically produced through transesterification, renewable diesel is synthesized through hydro-treating. This process removes oxygen from the feedstocks, resulting in a cleaner and more energy-dense fuel that is chemically identical to petroleum-based diesel. 

Environmental Benefits: 

  1. Reduced greenhouse gas emissions: One of the primary advantages of renewable diesel is its significant reduction in greenhouse gas emissions. Studies have shown that renewable diesel can reduce carbon dioxide (CO2) emissions by up to 80% compared to petroleum diesel. This reduction is attributed to the use of sustainable feedstocks, which have a lower carbon intensity than fossil fuels.
  2. Improved air quality: Renewable diesel has lower levels of particulate matter, nitrogen oxides (NOx), and sulfur emissions than conventional diesel. Renewable diesel combustion produces fewer harmful pollutants, leading to improved air quality and a decrease in respiratory and cardiovascular health risks for both urban and rural communities.
  3. Sustainable feedstock utilization: Renewable diesel can be produced from a wide range of feedstocks, including used cooking oil, animal fats, and waste oils. By utilizing these feedstocks, the fuel industry can promote the circular economy by reducing waste and repurposing materials that would otherwise end up in landfills. Furthermore, growing dedicated energy crops for renewable diesel production can be done sustainably, without deforestation or compromising food production. 

Advantages Over Traditional Biodiesel:  

  1. Compatibility with existing infrastructure: Unlike traditional biodiesel, renewable diesel can be seamlessly blended with petroleum diesel or used as a drop-in replacement without modifications to existing diesel engines or distribution infrastructure. This characteristic makes it an attractive option for achieving immediate emissions reductions in the transportation sector.
  2. Superior cold-weather performance: Renewable diesel exhibits excellent cold-weather performance compared to conventional biodiesel. It has a lower cloud point and a higher cetane number, which ensures better ignition and combustion even in cooler climates. This attribute makes it a more reliable fuel choice, particularly in regions with frigid winters.
