Star Oilco Speaks On Decarbonizing Heavy Duty Trucks 1000 667 Star Oilco

Star Oilco Speaks On Decarbonizing Heavy Duty Trucks

Decarbonizing Heavy Duty Fleets By Using B99 Biodiesel.

Mark Fitz joined the Clean Cities Coalition Mindful Mobility Tech Talk series for their High GHG Reductions webinar to speak on the benefits of B99 and how fleets can begin decarbonizing their emissions today!
On September 28th, 2022, three representatives were invited to speak on how they are not only saving large amounts of energy but are also having a big impact on reducing greenhouse gas emissions.

B99 Biodiesel reduces CO2 footprint of a 105,500 GVW truck and trailer by more than half at a lower cost than petroleum diesel.
How Can I Utilize B99 or B100 in My Own Fleet?

Star Oilco uses The Vector System developed by Pittsburgh-based Optimus Technologies. The Vector System is the only EPA-compliant biodiesel engine system and upgrades any medium or heavy-duty engine to operate on 100% biodiesel. It can be installed in as little as 12 hours. Learn more about The Vector System by contacting Optimus Technologies here directly or by reaching out to Star Oilco locally.

Star Oilco’s Field Test

Star Oilco has fielded the Optimus Technologies system on our 105,500 GVW truck and trailers.  Star Oilco began with a single Freighliner truck and trailer operating a Cummins ISX as a trial.  This truck’s typical route was approximately 305 miles round trip from Portland, Oregon to Grays Harbor, Washington.  This run is from Star Oilco in Portland, Oregon to the Grays Harbor REG Biodiesel plant and back to the Portland terminals for delivery of this product.

Over the last year and a half this truck has performed amazingly well, the only maintenance concern is swapping the fuel filters more regularly with every oil change.  Mileage and power difference are negligible as noticed by drivers or our Elog system.  On a few occasions a loss of power was experienced requiring an in between service fuel filter swap.

In Oregon the state ensures there is a cost associated with the CO2 intensity of a fuel.  This is why Biodiesel is consistently lower cost than petroleum Diesel fuels on the West Coast.  Get ahead of this curve and ensure your fleet benefits.


Why B99 Biodiesel was used in the past?

Prior to 2007 emission systems on modern diesels B99 Biodiesel was commonly used by fleets.  The fact that Biodiesel is a domestic, renewable and low CO2 fuel with a benign tail pipe emission made it popular.  B99 was the preferred fuel of dozens of fleets in the Pacific NW.  After the EPA requirements starting in 2007 which added particulate traps, SCR, their dosing systems, and the general complexity of these clean diesel systems on modern diesels, B99 became problematic.  Specifically the Tier 3 and Tier 4 diesel emission systems had a habit of choking on high blends of Biodiesel approaching B99.  This issue has been solved by Optimus Technologies Vector System.

Why B99 Biodiesel is the solution for Heavy Duty Diesel fleets seeking a Low CO2 solution today?

The Optimus Technologies Vector System provides the solution by enabling two tanks of fuel.  One tank dedicated to the diesel or R99 Renewable Diesel and the other tank dedicated to B100 or B99 pure Biodiesel. These systems optimize the systems of your modern Diesel fleet while also optimizing the performance and realities of the emission systems.

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.

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.  Anecdotally 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.

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.

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.  There are quite a few newer Renewable Diesel projects coming on line 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 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 are two major projects underway: Red Rock Biofuels in Lakeview, Oregon and Next Renewable Fuels in Port Westward, Oregon.

Red Rock Biofuels is focused on making renewable jet fuel, which is expected to be completed and in operation sometime in 2019. Next Renewable Fuels does not have a disclosed completion date.

Is renewable diesel being made in Washington state?

BP and Phillips 66 have Renewable Diesel projects under permitting or construction in Washington state.  BP’s Blain, Washington refinery and Phillips 66 Ferndale, Washington refinery are where these developments are taking place. These projects are added to existing petroleum refineries as a strategy of lowering the CO2 content of the refined diesel fuels from their plants.

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 is Heating Oil? 150 150 Star Oilco

What is Heating Oil?

In the Pacific Northwest heating oil is diesel.

Star Po;cp Crest

New heating oil customers often ask us, “What is heating oil?” Heating oil is diesel fuel and there are several grades and types. For Star Oilco our standard heating oil product is a ultra low sulfur diesel with a 5% biodiesel blend in order to meet Oregon mandates for off-road diesel fuel. That way our heating oil trucks can also serve construction fueling, emergency back up generators, and other common off-road diesel uses.

Star Oilco has a simple Heating Oil FAQ available.

For full on fuel nerds though, check out this more in depth deeper technical dive below.  If we leave anything out please don’t hesitate to ask for those seeking a nerd-level understanding of heating oil, kerosene and bioheat.

There are three typically grades of heating oil you can order.

Number 1 Diesel

Number 1 diesel is also called Kerosene or Stove Oil. This fuel has a lighter specification than typical heating oil which enables it to burn better in a “pot burner” or wick heater. Kerosene has its own specification as the fuel used by wick heaters. Kerosene is typically Number 1 diesel but not all Number 1 diesel’s are kerosene due to the need to be taken up by a wick heater. Any biodiesel content in a kerosene product WILL NOT work in a wick kerosene heater. So be very aware of confirming that your kerosene has never come into any contact with a biodiesel blend of fuel.

Red Number 2 Diesel

Red dyed diesel also called Heating Oil, Dyed Diesel, Off-Road Diesel is the default heating oil fuel. The fuel is dyed red to denote no on-road fuel taxes are attached to it. When you call and ask for heating oil, this is the fuel you are requesting. Clear or Green Number 2 Diesel is the fuel sold at retail gas stations and truck stops. That fuel will also work in your furnace, you just are paying for on-road taxes attached to that fuel.

Bioheat or Biodiesel Heating Oil

“Bioheat” is a blend of biodiesel and petroleum diesel to make a lower emission and lower CO2 heating fuel.  Typically Bioheat is Number 2 Heating Oil with a 20% blend of biodiesel or higher in it. It is a drop-in fuel for your heating oil furnace. There is no change other than routine maintenance is required. It is a cleaner burning fuel with a significant drop in CO2 emissions associated with your heating oil fuel consumption.  If you would like more information on biodiesel as a heating oil you can follow this link.

Where do heating oil companies get their fuel?

In the Portland, Oregon market, diesel is fungible. Everyone buys or is expected to mix their fuel from each other in some way. Primarily this is due to the Portland/Vancouver market receiving most of its fuel down the Kinder Morgan-operated Olympic Pipeline, which means all the refiners transporting fuel are mixing their product in transit. Additionally, there are shared terminal locations, which also have co-mingled owned diesel products. Every refiner is typically expecting to mix their diesel and gasoline products. The difference is in the care a vendor takes to filter the fuel, using additives and continuously check their fuel quality. If you are buying at the absolute lowest price possible, know that there is an incentive to skip any added value of quality assurance.

Star Oilco buys our diesel products from a variety of vendors. The source refiner typically being either BP, Shell, Marathon(formerly Tesoro), Phillip 66, or a number of other refiners.

Portland, Oregon and Vancouver, Washington are not unique in in having fungible diesel and heating oil fuel specifications. Through its Pacific Operations unit, Kinder Morgan operates approximately 3,000 miles of refined products pipeline that serves Arizona, California, Nevada, New Mexico, Oregon, Washington and Texas. With roots dating back to 1956, it is the largest products pipeline in the Western U.S., transporting more than one million barrels per day of gasoline, jet fuel and diesel fuel to our customers. The company-owned terminals also provide additional services, such as liquid petroleum product storage and loading facilities for delivery trucks.

The heating oil and biofuel blends Star Oilco sells its customers

Heating oil is essentially off-road diesel. You can legally use a higher sulfur content for boilers and heating systems than you can off-road equipment and back-up generators. Regardless, we sell the lowest sulfur fuel available and optimize our fuel to be as versatile to our customers as possible. Construction equipment, back up generators and a host of others systems use off-road diesel, as do heating oil systems. Star Oilco sells the same diesel fuel specification for all of our off-road uses. We also blend this fuel with biodiesel for our customers that want higher blends of low CO2 biodiesel fuels and heating oil. Star Oilco carries nothing but ultra low sulfur diesel fuels. In fact, our minimum blend of biodiesel is a B5 biodiesel blend (5% biodiesel and 95% petroleum diesel) and we also offer B20 (20% biodiesel blend) and B99 (99% pure biodiesel) for our customers.

About Diesel Fuels Specifications 

In the United States, diesel fuel is controlled according the American Society for Testing and Materials Standard D975-97. This standard describes a limited number of properties that diesel fuels must meet. It should be noted that the requirements are all performance-based, meaning they do not mandate the composition of the fuel, only the specific performance related requirements demanded of a fuel for a diesel engine. The requirements of D975 are described below.

ASTM Specifications for Diesel Fuel Oils (D975)*

*More info on ASTM specifications

Diesel fuel is characterized in the United States by the ASTM standard D975, which identifies five grades of diesel fuel. We are only going to talk about the two most popular commercially diesel fuel used — No 1 and No. 2 diesel. The ASTM D975 standard is made up of a series of different tests that check the characteristic ranges of a fuel to confirm it is adequate to operate in your equipment. In simple terms, they are checking for specific gravity, the vapor point (when it turns into a gas), the flash point (when it catches fire), the dirt content, water content (how much microscopic entrained water) and a host of other requirements diesel must meet in order to be legal to be sold for use in your engine.

Grade No. 1-D and Ultra-Low Sulfur 1-D:

This is a light distillate fuel for applications requiring a higher volatility fuel to accommodate rapidly fluctuating loads and speeds, as in light trucks and buses. The specification for this grade of diesel fuel overlaps with kerosene and jet fuel, and all three are commonly produced from the same base stock. One major use for No. 1-D diesel fuel is to blend with No. 2-D during winter to provide improved cold flow properties. Ultra-low sulfur fuel is required for on-highway use with sulfur level < 0.05%. 

Grade No. 2-D and Ultra-Low Sulfur 2-D:

This is a middle- or mid-grade distillate fuel for applications that do not require a high volatility fuel. Typical applications include high-speed engines that operate for sustained periods at high load. Ultra-low sulfur fuel is required for on-highway use with sulfur level < 0.05%.

Biodiesel Fuels for Heating Oil

Biodiesel is a renewable fuel produced from oil seed crops, used cooking oil, and/or animal fat waste. It is chemically similar to petroleum diesel, and is produced by combining the oil stock with catalysts and then heating it. Biodiesel is not the same as vegetable oil or SVO (straight vegetable oil). Biodiesel can be used in any diesel engine. Biodiesel and biodiesel blends significantly reduce tailpipe emissions, especially carbon dioxide, carbon monoxide, sulfur dioxide and particulates (black smoke). ASTM D975 standard, as of 2008, allowed up to 5 percent biodiesel to be blended into the fuel. This is the called B5 — the ‘B’ stands for biodiesel and 5 stands for up to 5 percent biodiesel.

B6 to B20 – ASTM D7467-17:

Diesel blends up to 20% and more than 6% are referred to as B20. Biodiesel is a cleaner burning fuel than petroleum diesel. Using biodiesel can help reduce the amount of harmful emissions released into the air, including sulfur dioxide, carbon monoxide, polycyclic aromatic hydrocarbons and other compounds found in diesel exhaust. Read the ASTM D7467-17 standards.

B99 & B100 –  ASTM D6751-15ce1:

These are fuels made of up to 100% biodiesel. Due to environmental regulations, most retailers will carry a maximum of B99. The standards for B99 and B100 are identical. Unlike gasoline, diesel can gel at cold temperatures, which can cause stress on fuel pumps and fuel injection systems, or can clog filters or even become too thick to pump to the engine. B99 has a higher temperature gel rate – meaning that it begins to cloud and thicken at higher temperatures – than conventional diesel. “The cloud point of soybean biodiesel is about 34°F (1°C), whereas the cloud point for No. 1 diesel is about – 40°F (-40°C) and for No. 2 diesel between -18°F (-28°C) and +20°F (-7°C).” (Biodiesel Cloud Point and Cold Weather Issues) The solutions for cold weather involve additives and lower blends to ensure continuous operations. Read the ASTM D6751-15ce1 standards.

Can you Bio diesel as a Heating Oil Fuel?

In a recent study, the viability of biodiesel – also known as bioheat – and its use as a heating oil was examined.Star Oilco an experienced provider of BioDiesel Heating Oil

TL:DR Biodiesel up to B20 and beyond do not require equipment changes or settings. Home heating systems have used biodiesel since 2000 and have shown no significant issues compared to standard fuel.

The study reviews pump seal performance, metal interactions, burner combustion and even reviews in-the-field users of biodiesel.

Use of biodiesel reduces GHG (Greenhouse Gas) by 50% – 86% compared to petroleum diesel, according to NORA.

 

In a study from Brookhaven National Laboratory that was submitted to the National Oilheat Research Alliance (NORA), Dr Thomas A. Butcher and Rebecca Trojanowski studied the use of Biofuels in Heating Oil and any possible issues that could result from usage.

Biodiesel mixtures are labeled as B* where the * is the percentage of biodiesel. For example B20 would be 20% biodiesel and 80% petroleum diesel.

By breaking it down into 5 separate studies and a review of actual field use for nearly 20 years, they set out to evaluate the possible fail points of using B20 and higher heating oil blends.

Bio Diesel and Pump Seal Material Evaluation

From the start, the pump shaft seals were identified as the area with the most concern of failure. So, this is where the study began. They identified the most common seals in pumps for North America were nitrile material. The study then focused on this material.

For this part of the study, they took the nitrile material and immersed it in different biodiesel and No.2 fuel blends. They soaked these for 670 hours at 125 °F.  The samples were than checked to see if the hardness changed, looked at swelling, tensile strength, and compression deformation.

Results: There were no significant changes for the nitrite for fuels meeting ASTM standards. This includes biofuel up to B100. The one concern was fuel that had acid numbers above 2 could lead to accelerated degradation. B100 standards call for acid numbers 0.5 and below.

Biodiesel and the Evaluation of Oil Burner Pumps Under Operating Conditions

This second test also dealt with the same seals. The difference in this test was that the pumps were in continuous action. They set up 42 pumps to run for 11 months. A pump would run for 5 minutes and then turn off for a minute. This resulted in 80,000 on/off cycles in a period of 8,030 hours. During this time no leaks were observed in any of the pumps.

Result: There wasn’t any difference in degradation between using B0 and B20.

Exposure of "Yellow Metals" at low temperature with biodiesel

Copper fuel lines are installed in many older oil heating homes. This was due to lower cost and the fact they were easy to manipulate during installation. This could be a problem because No.2 fuel and biodiesel could accelerate the oxidative degradation of the fuels when exposed to copper.

This experiment consisted of using 10 inch tubes filled with different levels of biofuels: B0, B20, and B100. These would be stored at 70 °F  for 6 months in 3 types of tubes: stainless steel, old copper (a fuel line that had been in service for 30 years), and new copper. Most systems only would expose the copper pipes for a very limited time, so 6 months for any exposure is an extreme amount of time.

Results: An acid value of 2 was shown to degrade nitrile material in the earlier experiments. None of the fuel crossed this mark. The closest was B0 in the stainless steel. This fuel got to 1.5 from .04 (where all the fuel started). These tests were considered to represent summer shutdown of a heat-only boiler or furnace.

Exposure of "Yellow Metals" and biodiesel at high temperature

In addition to copper fuel lines, the other major source of yellow metal would be the brass nozzles. Most fuel isn’t in the nozzle long enough to cause any changes, but the fuel left unburned between firings is exposed to higher temperatures then those in the lines. It was decided to try and see if there was changes for this exposure.

The experiment was open top glass beakers with brass and stainless steel nozzles stored in B0, B20, and B100 levels of fuel. This setup was stored in an oven at 175 °F for a week.

Result: The result was a relatively small increase during this time. Even after the experiment was continued for another 4 weeks the numbers represented no significant differences.

Biodiesel Combustion Performance and Flame Sensor Response

The goal of this experiment is to evaluate the proper atomization and combustion performance of biodiesel blends in heating oil systems and to see if there was any issues with flame sensor operation and effectiveness.

The fuel for a home heating oil system requires the fuel to be pushed through a 10 micron filter and then pushed into a fire box at 100 – 150 psi and ignited. This is compared to a diesel engine that have a nominal pore size between 2 and 30 microns and then injected into the system at 20,000 psi.

According to the study, “In comparison to the… diesel engine, heating oil systems are open flame systems and excess air is used to ensure complete combustion. The amount of excess flue gas oxygen is generally between 3% and 6% excess O2 or 15% and 40% excess air to minimize smoke and ensure very low levels of carbon monoxide.” These are usually set by a technician and then re-checked on service calls every 1 or 2 years. “Since properly operating home heating oil systems burn the fuel completely in excess air and emissions are low… Due to this clean combustion, heating oil emissions are typically not measured or monitored, with the exception of smoke and CO.”

The testing was set up first for conventional No. 2 fuel and then adjusted for B100 fuel.

Result: Showed that B20 performed at the same level as regular No. 2 fuel and the bio blend could go all the way up to 50% before the need to adjust the airflow. So, the conclusion was that if the unit is running higher levels of biofuel, the air input needs to be adjust to optimize fuel combustion and reduce CO or smoke.

Review of Field Experience with BioDiesel Blends

Biodiesel blends have been used in the field for heating oil with some using B20 and above since 2005. Part of the study was reviewing customers that have been using B20 above. Of the surveyed providers, none reported a change of any burner or system components.

The report continues to talk about the levels of biofuel that was being used and the condition the fuel was in. Basically it was found that there was no difference from the standard petroleum only fuel.

Conclusion and results of BioDiesel study

  1. Fuels above a certain level of acid content can compromise seals, none of the bio blends reached this and they were statistically similar to petroleum only fuels.
  2. Long term cycling pump showed no leakages with biofuels.
  3. No impact on fuel stored in copper tubing at room temperature was found.
  4. No significant difference on fuel stored with copper at high temperatures and conventional No. 2 fuel.
  5. At higher than B50 concentrations it was found that the burner needed adjusted for best efficiency. B20 will operate at the same level as standard No. 2 fuel.
  6. Finally there appears no real difference in functional use of biofuel vs the use of No. 2 fuel.

So the good news, according to this report, is that if you want to use biodiesel up to B50 there appears no difference in settings or maintenance. As long as a reputable dealer that uses biodiesel that uses ASTM D675 for its B100.

Using biodiesel blends for heating oil reduces greenhouse gases. For more information on this see the NORA report.

“Prohibits retail dealer, nonretail dealer or wholesale dealer from selling petroleum diesel for use in motor vehicle on or after specified dates. Requires public improvement contract to require that motor vehicles be powered by fuel other than petroleum diesel. Prohibits public body from using petroleum diesel in motor vehicle under control of public body”

HB 3305 mandates non-petroleum diesel be the only legal fuel for sale to diesel powered motor vehicles in Oregon.

Star Oilco has customers ask about this proposal and how real it is?  In Oregon the focus on low CO2 fuels in the legislature is so consistent we can expect this to not go away.  Even if HB 3305 does not move this Legislative session, this will not be the last of biofuel mandates.  For this reason Star Oilco has been working to be ahead of the curve with non-petroleum diesel substitutes. Star Oilco has been selling B99 biodiesel since 2002 and renewable diesel since 2015.  If your fleet has an interest in learning more about low CO2 fuels or try these fuels, Star Oilco is ready to serve you with both R99 renewable diesel and B99 biodiesel.

News coverage of Oregon HB 3305 is below

The Center Square’s Oregon, whose coverage of this has been syndicated to many other online news organizations, lead with the headline: Bill in the Oregon Legislature would ban diesel fuel sales by end of decade.

CDL Life had this to say: The bill would begin to ban the sale of “petroleum” diesel by “non-retail dealers” as soon as 2024 in Clackamas, Washington or Multnomah counties and state-wide by 2027.

Landline as well has following the story: Oregon bill would ban petroleum diesel. Later in the article they add this to the background of HB 3305’s origin: Power said in a statement that her goal is to phase out petroleum-based diesel and replace it with renewable diesel. She says she introduced the bill on behalf of Titan Freight, a local trucking company she says has already transitioned to renewable diesel.

KXL covered this local news quoting Oregon State Representative Shelly Boshart-Davis, a legislator who owns a trucking company and actually buys quite a bit of petroleum diesel.

Lars Larson radio interviews Rep. Shelly Boshart-Davis about HB 3305.

KQEN news radio in Douglas County also covered it with the headline: GOP says supermajority declares war on working class.

The Wildcoast Compass covered the story quoting Rep.Vikki Breese-Iverson (R-Prineville): “There is absolutely no way we can implement this legislation in accordance to these timelines without extreme disruption to Oregonians’ daily lives and the obliteration of our economy as we know it,” 

Oregon Public Broadcasting covered HB 3305 a few days after the bill dropped which might be an indication it’s moving forward. From the story: One bill, House Bill 3305, would set a staggered timeline for ending sales of diesel in the state — first in the Portland area, then throughout Oregon. Its backers hope to spur widespread use of “renewable diesel,” a product with far lower emissions that can be used in any diesel engine. They say the fuel could be an important and near-instant way for the state to cut into greenhouse gas emissions while other technologies emerge.

The Banks Post covered HB 3305 as well with the headline: Diesel fuel under fire in Oregon legislature.

What HB 3305 means in the real world?

HB 3305 means the petroleum diesel used by any commercial vehicles operated on Oregon’s highways will be replaced with biofuels.

Biofuels will replace on-road petroleum diesel at all Oregon:

  • Retail gas stations
  • Trucks stops
  • Commercial cardlocks (Pacific Pride and CFN)
  • Privately owned bulk tanks
  • Mobile on-site fueling (wet hose fueling), and
  • All other bulk deliveries of diesel fuel.

Given the media coverage of this law, which no doubt will grow if this bill progresses to hearings.  Star Oilco wanted to provide more background of what this law would mean for Oregon.  We hope this provides in depth information about what the options are for diesel fuels and a whole host of background information.  The news coverage so far fails to really provide this depth and background for those with concerns.  If you have questions, please do not hesitate to ask. Star Oilco seeks to be a neutral and accurate source of information.

Star Oilco sells renewable diesel in bulk and by our mobile on-site fueling service. It is worth mentioning from our first hand experience that users of it become raving fans.  Renewable diesel is a new fuel that many believe out performs petroleum diesel in every way. Many customers who have used it experienced improvements in horse power, fuel economy, and emission regeneration system performance.

Currently renewable diesel is in extreme high demand, limited production, and commands a high premium over petroleum diesel with few sources of supply.  Renewable diesel has some major backers in the trucking industry as well as OEMs.  As the availability of this next generation fuel grows, the number of plants manufacturing it expands, and it’s price comes down, this type of law may make far more sense.

If petroleum diesel is no longer legal for sale in Oregon, what does that mean diesel vehicles will use?

There are two immediately available diesel rated biofuels that can replace petroleum diesel.  These are two very different fuels. Renewable Diesel and Biodiesel have differences in their properties.  So please don’t confuse biodiesel and renewable diesel as the same fuels.

Biodiesel and Renewable Diesel are very different fuels.

Biodiesel is a proven and longtime available fuel in Oregon.   Biodiesel is not actually a hydrocarbon diesel though, it is a diesel like biofuel made from vegetable oil usually sold in a 5% to 20% blend with petroleum diesel. It is not recommended to run pure biodiesel in late model diesel engines if they have a particulate trap.  This differs from Renewable Diesel which is a next generation synthetic hydrocarbon diesel made from various feedstocks including vegetable oil.  It is actually diesel, it can be used as a pure drop in fuel without any blending with petroleum diesel.

What are non-petroleum diesel fuels?

Oregon HB 3305

Biodiesel or B99 (99% Biodiesel + 1% Petroleum Diesel)

Renewable Diesel or R99 (99% Renewable Diesel + 1% Petroleum Diesel)

Blends of Biodiesel and Renewable Diesel (branded REG UltraClean Diesel)

HB3305 allows for biofuels in replacement for diesel.  We assume that change would be from a current Oregon fuel mandates of B5 or R5 biofuel diesel blend to a B99 or R99 mandated fuel.   Under current Oregon law all diesel fuel must contain a 5% blend of biodiesel or renewable diesel.  Oregon’s biofuel content law can be read at ORS 646.922 and we can assume this would change that to a 99% mandate. Why 99% instead of 100%, that is a good question relating to Federal regulation of the US diesel and gasoline markets.

 

Why does this require a 99% blend (B99/R99) instead of 100% biofuel?

The reason biodiesel and renewable diesel are sold at a 99% blend is because of Federal rules associated with how petroleum companies must handle these fuels.  For this fuel to be used under the US EPA’s Renewable Fuel Standard program biodiesel and renewable diesel must be blended at a minimum 1%.  When fuel is blended at 1% with diesel, the EPA enables it to generate a “Renewable Identification Number” or “RIN” which is regulated to ensure a minimum amount of biofuels is used in the stream of commerce for fuel in the United States.  This Federal program is separate and unrelated to any program in Oregon, though the law recognizes and seeks to align with the framework created by the EPA.

What are the fuels HB 3305 would allow to be used by diesel motor vehicles in Oregon if this bill was passed into law?

The two fuels immediately available if this law was passed into law are B99 Biodiesel and R99 Renewable Diesel.

Both of these fuels exist today but have their own drawbacks.  In a nutshell, B99 is not a drop in substitute for petroleum diesel.  It is recommended to be blended at 20% with petroleum diesel (NOTE: B99 biodiesel can be used in modern diesel with an up-fit kit provided by Optimus Technologies).  On the upside, biodiesel is plentiful and competitive with petroleum diesel in cost.  If HB 3305 passed though this plentiful fuel wouldn’t be a ready substitute beyond a 20% blend with renewable diesel or with mechanical changes to existing trucks.  Contrast this with  R99 renewable diesel as a drop in ready to go substitute for petroleum diesel.  It is ready to use without blending, but has the downside of being in short supply and at a cost premium above petroleum diesel.

If Oregon’s over 2,000,000 gallons of diesel usage a day (or 750+ million gallons a year) was mandated to renewable diesel no doubt that premium would probably exceed $2 a gallon over petroleum diesel given R99’s lack of ready additional supply.  This $5 a gallon presumes that Oregon would have to pay more for the existing renewable diesel supply finding it’s way to California with several dollars a gallon of value paid for it’s lower CO2 baseline value.  California has a Clean Fuel Standard and a CO2 Cap and Trade program which provide a monetary value for renewable diesel’s lower CO2 numbers.  Oregon has a Clean Fuel Program as well, but it’s program does not pay as much for low CO2 fuels as California, making low CO2 fuels such as renewable diesel more expensive in Oregon.

B99 Biodiesel in depth.

Blends of biodiesel below 20% are extremely common in Oregon.  All fuel must contain at least 5% biodiesel content and many retail outlets, cardlocks, and major truck stops commonly sell a 10% to 20% blend of biodiesel around the state.

Biodiesel is a diesel like fuel manufactured by a chemical reaction called transesterfication, typically from vegetable oil or recycled cooking oil.  It is made by a relatively simple process and biodiesel has been a proven fuel in use in Oregon for nearly twenty years.  Star Oilco started handling and selling biodiesel in 2002.  Prior to 2007, B99 was commonly used by many commercial fleets due to it’s huge reductions in tail pipe emissions.  Vehicles manufactured after 2007, are clean diesels.  The US EPA required new clean diesel emissions systems which are impressive in their ability to make modern diesel engines extremely clean, but they can only handle biodiesel blends below B20 or 20% biodiesel unless an upgraded system is added.

Today B99 is a possible fuel for a modern clean diesel fleet with an upgrade to existing vehicle fuel supply system.  Optimus Technologies has an approved technology to enable a modern diesel aftertreatment system to operate without problems on B99.   Star Oilco has purchased five of these systems and is currently fielding them in the Pacific NW.  We expect these systems to be mainstream in coming years, but just like Renewable Diesel the technology is newly available and scaling up.

If you are interested in using biodiesel in your fleet, you can contact Star Oilco with questions or if you want to start researching we highly recommend starting with this US Department of Energy handbook titled Biodiesel Use and Handling.

 

R99 Renewable Diesel in depth.

Renewable Diesel is a next generation biofuel made from fats, oils, and greases. It is not an alternative diesel, renewable diesel is a petroleum free hydrocarbon diesel fuel. It is diesel! Renewable diesel not only less than half the CO2 of diesel refined from petroleum fuel, but it is cleaner burning and has shown evidence of reducing the cost of maintenance in fleets using it. Renewable diesel is a profound technology which has the potential to use the lowest grade trap greases, sewer materials, rendering wastes, municipal garbage, and a host of other refuse products making them into this high performance, sustainable, low CO2 diesel.

There are two categories of technology that renewable diesel is made from.  Hydrogenation and Fischer Tropsch process.

Renewable Diesel from Hydrogenation or Hydrotreating

Hydrogenation derived renewable diesel is very similar in manufacture to modern petroleum diesel in that the molecules of a the feedstock is cracked and reformed in the presence of a catalyst to form a very specific series of hydrocarbon molecules.  These being diesel and propane range fuels. The feedstocks used by renewable diesel plants are vegetable oils and animal fats.

The hydrotreating plants providing renewable diesel to Oregon currently are Neste from a plant in Indonesia, Diamond Green (in a joint venture with Valero), Sinclair, and Renewable Energy Group. All of these plants are over subscribed and 100% of their production is being taken at a premium primarily by the California low CO2 fuels market.   There are several new renewable diesel plants under way though.  Holly Frontier, Marathon, CVR Energy, and Phillips 66 are converting existing petroleum refineries into renewable diesel plants.  This process costs billions of dollars, will take years to complete, and also will be likely destined for California’s low CO2 fuel market with smaller markets like Oregon being an afterthought.

Renewable Diesel from Fischer Tropsch process.

Currently there are a number of smaller demonstration facilities making renewable diesel from wood waste and other feedstocks.  The largest proposed project currently on the books is Illinois Clean Fuels which will be collocated with major CO2 capture facility making their product negative CO2.  Fischer Tropsch renewable diesel is expected to be the future of refining given it’s flexibility of feedstock.  It’s process enables the use of municipal garbage, agricultural waste, woody biomass, and other low value plentiful materials as feedstock.  Given that the United States is called by some the “Saudi Arabia of garbage” we have plenty of supply waiting for a higher and better use as low CO2 transportation fuel.  Illinois Clean Fuels has a great explanation of how Fischer Tropsch makes renewable diesel and jet fuels.

Where can you get Renewable Diesel in Oregon?

Star Oilco currently is selling R99 Renewable Diesel for commercial use.  We can deliver to fleets seeking it in bulk or mobile onsite delivery (wet hose R99 diesel service begins Spring 2021).  If you fleet wants to trial renewable diesel, Star Oilco can work with you on a loaner tank for a 90 day demonstration of the fuel.  Call Star Oilco if you have an interest in Renewable Diesel for your fleet 503-283-1256.

Every Question We Have Been Asked About Biodiesel

Every Question We Have Been Asked About Bio-diesel

What is biodiesel?

Biodiesel is a renewable, clean-burning diesel replacement that is reducing U.S. dependence on foreign petroleum, creating jobs and improving the environment. Biodiesel is commonly blended in a 5% to 20% component with petroleum diesel and can be found available at retail around North America as a blended fuel.  Biodiesel is a low CO2, net energy positive fuel which depending on the feedstock it is made from can vary from a 30% to 80%+ reduction in CO2 emissions compared to petroleum diesel.  Biodiesel is made from a diverse mix of feedstocks including recycled cooking oil, industrial non-food grade spent oils, animal fats, as well as virgin vegetable oils such as canola, soy, and corn oil. For more information see the National Biodiesel Board’s “Biodiesel Basics” page.Simple Bio-diesel chart showing how to make

How is biodiesel made?

Biodiesel is most commonly made from taking an animal fat, used cooking oil, or a virgin vegetable oil and mixing it with an alcohol (such as methanol). This process is called transesterification and it creates two products glycerin and esters (usually methyl esters or alkyl esters which is the chemical name for most biodiesel).  The crude biodiesel is then further processed to remove excess water and other impurities. The standards for commercially sold biodiesel in the US is ASTM D6751.

What does ASTM D6751 mean?

Biodiesel to be sold in the United States must meet an industry standard which is ASTM D6751.  ASTM (American Society for Testing and Materials) D6751 is the specifications for B100 or 100% Biodiesel.  Biodiesel is usually blended with diesel fuel for retail sale.  This specification defines the properties of the biodiesel from the refiner prior to sale to the public. The properties include things like flashpoint, water content, oxidative stability, sulfur ppm (parts per million), and other specifics that this biodiesel needs to be at in order to hit these standards (Source).

Once a fuel is within all these properties it can be blended with diesel, which has its own ASTM standards, for more about ASTM D975 and other fuel specification concerns please see the Changes in Diesel Fuel – Technicians Guide for more and very in depth information.

Can biodiesel be used in normal diesel engines? / Which cars use biodiesel?

Regardless of where you are in the United States there is a reasonable expectation of purchasing biodiesel in your diesel fuel.  Formally, B5 is supported by all major OEMs selling diesel engines in the U.S. In 2016, at least 78 percent of diesel vehicles supported B20 (Source).  Regardless of what your owner manual says about biodiesel fuel, B20 biodiesel is a proven fuel and is automatically presumed for any new diesels on the road. In many parts of the United States B20 is a commonly found fuel at retail stations, commercial cardlocks, and national truck stop chains.

In the Pacific Northwest, where low CO2 emission policy is front and center, biodiesel can be expected to be found in every gallon of diesel sold in some form.

Oregon law says “All diesel fuel sold in the state must be blended with at least 5% biodiesel (B5) if that fuel is going to be used in vehicles. For the purpose of this mandate, biodiesel is defined as a motor vehicle fuel derived from vegetable oil, animal fat, or other non-petroleum resources, that is designated as B100 and complies with ASTM specification D6751. Renewable diesel qualifies as a substitute for biodiesel in the blending requirement” (Source).  Oregon and Washington has plenty of retail and commercial cardlock locations selling above 5% biodiesel as the defacto fuel given the incentives as well as low CO2 mandates in Oregon.

Can biodiesel be used for heating oil?

Yes. Biodiesel has been effectively used as a heating oil for over 20 years. In fact an in-depth report by the Sustainable Energy Technologies Department Energy Conversion Group shows that blends up to B50 can be used without needing to change or adjust your settings. Read our blog for a summary of this report.

Can biodiesel be mixed with conventional / regular diesel?

Most biodiesel that is sold is as a blended form with petroleum diesel. In a blend, the “B” stands for the amount of biodiesel that is included in the product. For example, B20 would be 20 percent biodiesel and 80 percent petroleum diesel. Biodiesel can also be combined with renewable diesel – a blend of B20 would be called B20/R80 diesel.

[videopack id=”4038″]https://www.staroilco.net/wp-content/uploads/2021/03/B20-a-proven-fuel.mp4[/videopack]
Can biodiesel be used in diesel generators?

Yes. In fact, Oregon is one of several states that require biodiesel be blended into all diesel fuels. That means this fuel has been used successfully in the fuel supply for years. As with any fuel that can sit for extended amounts of time, we recommend you take proper precautions, such as using additives, to ensure your fuel is ready to be used when needed. If this is a concern, please contact us – we would love to talk to you about your storage needs.

Can biodiesel be made from animal fat?

Yes, biodiesel refers to (according to the National Biodiesel Board) a methyl ester made from chemically reacting lipids with an alcohol to produce fatty acid esters. This is called transesterification. The lipids could be sourced from many different types of oils, such as vegetable, soybean or animal fat based oils/tallows. For a deeper dive into some of the different types of feedstocks, read our blog.

Can biodiesel be used in airplanes?

Yes and no. There have been several tests using biofuels but fuel for aircrafts is different than regular diesel. Fuel gels at a plane’s flying altitude so aircrafts can’t use regular diesel or biodiesel. Several tests with biofuels have proven successful. Read more about the use of biofuels in the future.

Can biodiesel freeze?

Gelling is the term used for diesel fuel starting to freeze. The paraffin present in diesel starts to solidify and at lower temperatures, it can start to solidify and crystallize. Some blends of biodiesel at B20 and higher will gell at a higher temperatures than petro diesel. During the winter months, it’s important to use additives that combat this or use lower percentages of biodiesel for your fuel. In low enough temperatures, even petro diesel will freeze.

Can biodiesel replace oil? / Can biodiesel replace diesel / fossil fuels?

At this time, no. While the quality of the fuel for biodiesel and renewable diesel is as high as the petrodiesel we have today, the production of these fuels can’t meet the demand that is needed. This has to do with available feedstock and infrasturcture to recycle usable wastes.

The long answer to this question, though, is YES. As technology advances, there may be a time that all fuel is derived from waste and plant crops instead of petroleum.

For an idea where the market is going and how much fuel we are using here is a little bit more information on current usage.

In the early 2000’s, the biodiesel market was about 25 million gallons. In 2016, the market had grown to 2.8 billion and it’s still increasing. The on-road diesel demand is 35 billion to 40 billion gallons. The industry goal is to be producing 10 percent of the transportation market by 2022 (Source).

Which biodiesel is best?

Biodiesel that meets the ASTM D6751 is the best. While making your own biodiesel isn’t hard, keeping the fuel filtered and free of excess water is challenging. Finding a reputable provider that uses fuel that meets specs and also filters and treats your fuel like Star Oilco helps ensure you’re using the best fuel possible.

Which is biodiesel plant/crop? What crop/plant produces/yield biodiesel?

Any plant that produces an oil can be used to produce biodiesel. The plants and crops that are most likely to be used, would produce a lot of oil for the amount of work that goes into growing them. Some of the experimental crops are ones that grow in areas that don’t produce quality food, like Camelina sativa. A member of the mustard family, it grows well in poor soil and harsh conditions and doesn’t displace crops that produce food.

Here are the blogs we have posted so far about some of the biodiesel feedstocks that have been tested and used.

Feedstock: Babassu oil & Beef Tallow
Feedstock: Borage Oil & Camelina Oil
Feedstock: Algae Oil & Canola Oil
Feedstock: Castor Oil and Choice White Grease
Feedstock: Coconut Oil and Coffee Oil
Feedstock: Evening Primrose Oil and Fish Oil
Feedstocks: Hemp Oil & High IV and Low IV Hepar
Feedstocks: Jatropha Oil, Jojoba Oil, & Karania Oil
Feedstocks: Lesquerella Oil & Linseed Oil
Feedstocks: Moringa Oil & Neem Oil
Feedstocks: Palm Oil & Perilla Seed Oil
Feedstocks: Poultry Fat & Rice Bran Oil

Which is better: biodiesel or diesel?

Biodiesel has advantages of producing lower emissions, providing lubricity to the moving parts and being produced in the United States.

Diesel is more abundant, is easily created from crude oil, and has a lower gel point.

Which is better depends on what you are looking for.

Which states mandate biodiesel?

According to AFMP (American Fuel & Petrochemical Manufacturers):

  • Minnesota: Has a B2 requirement year round (September 2005) and a summer requirement of B20 (May 2018).
  • Oregon: Requires a B5 reguirement year round (July 2007).
  • Washington: Requires 2% of the diesel sold in Washington to be biodiesel (December 2008). This can be substituted with Renewable Diesel (July 2009).
  • Pennsylvania: According to AFMP, “2% biodiesel for on-road compression ignition engines one year after annualized in-state production reaches 40 million gallons, 5% biodiesel (100 million gallons), 10% biodiesel (200 million gallons), and 20% biodiesel (400 million gallons)” (July 2008). Renewable diesel can substitute for up to 25% of this requirement, in addition to heating oil and off-road diesel (May 2011)
  • New Mexico: Requires B5 for all diesel vehicles (July 2012).

Which countries produce biodiesel? / Which countries use biodiesel?

global biodiesel production by country
Biodiesel is produced around the world, led by the U.S., Brazil and Germany.

The US produced 6 billion liters in 2017 or about 1.6 billion gallons. This website has the exact numbers for 2017, 2018 and some of 2019 production of biodiesel in the U.S.

Biodiesel in the US is largely made from soybeans at this time.

United States Month Biodiesel Production 2017 to 2019

Will biodiesel damage my engine? / Will biodiesel damage my car?

Biodiesel can be used in any car or engine that is using diesel. Biodiesel is a solvent this means that it may start cleaning the tank or pipes that previously just used petroleum fuel, for this reason fuel filters may clog initially.

How will biodiesel help save money?

It depends! If the price of a barrel of crude rises to a high level, biodiesel can be cheaper. In addition, if RIN’s are available (basically a credit for using biodiesel), they can lower the price of biodiesel and make it less expensive to use and purchase.

How will biodiesel help reduce pollution?

Petrodiesel uses crude oil, which is trapped CO2 from ages past. When it is burned, it releases this CO2 back into the air.Average Biodiesel Emissions Compared to Conventional Diesel When you use biodiesel, you’re using CO2 that is being captured by the growing plants or the waste. This is current CO2 you aren’t adding to the net sum in the environment.

As for regular pollutants, here is a chart that shows what using biodiesel does compared to conventional diesel. There is a significant reduction to pollutants that are expressed through the exhaust.

How long will ecodiesel last? / How long can biodiesel be stored?

Diesel, including biodiesel, does go bad after awhile. Diesel fuels adhering to ASTM specification should be safe for storage up to a year without additional treatment and testing. If you are storing diesel for long term use, it is a good best practice to treat the fuel with a biocide and oxidative stabilizer to ensure that the fuel stays within specification and nothing will begin to grow in your fuel tank. The biggest enemy of long term diesel storage is water and dirt entering the fuel through a tank vent. As temperatures change, a tank will breath, pulling in air and moisture from outside. Keep your fuel within specification by ensuring there is no water in the tank and that outside contaminants can’t get into a tank.

Where biodiesel is used? / Where is biodiesel used in the world?

Biodiesel use is encouraged by many countries and usage has increased greatly since 2001. This graph from the U.S. Energy Information Administration shows that the U.S. used 2.1 billion in 2016 or about 22% of the total amount of biodiesel used that year. Wikipedia lists 31 countries and explains the amount of biodiesel they use each year. World biodiesel consumption, 2016

Where to buy biodiesel?

If you live in Oregon, every gas station has at least 5% biodiesel. Cardlock locations throughout the states have stations with biodiesel blends. For other locations, this site is a great resource.

Where can biodiesel be used?

Legally, it can be used anywhere although some biodiesel derived from palm oil is restricted in certain countries.

When / where was biodiesel invented?

The definition of diesel is a liquid that uses compression and oxygen to ignite without the use of a spark. Rudolf Diesel created the diesel engine in Germany. The design for engines first used coal dust suspended in water and later vegetable oils, such as peanut oil. These fuels were later abandoned when petroleum became abundant and cheaper to produce.

Where does biodiesel fuel come from?

In the United States, the primary source for biodiesel is soy beans. According to the U.S. Energy Information Administration, the feedstocks break down as such:

  • Soybean Oil – 52%
  • Canola Oil – 13%
  • Corn Oil – 13%
  • Recycled feedstocks – 12%
  • Animal Fats – 10%

Even with Soybean oil as the primary source, the remaining meal is used to produce food for animal feed. For more information on feedstocks of biodiesel, here is an ongoing blog we have been working on to examine the resulting fuels produced by the various feedstock.

Where are biodiesel plants?

Here is a list of sites in the United States.

When did biodiesel begin?

The original diesel engine ran on peanut oil, so technically biodisesel was first used in the 1890s. Most oils in the 1800s were from bio stocks. It wasn’t until petroleum became abundant and thus cheaper that biofuels and oils were abandoned for this cheaper source.

When does biodiesel gel?

The feedstock determines when biodiesel will gel. The most common feedstock is soy, which has a cloud point of 0°C (32°F) for B100. Petroleum diesel has a cloud point of -45°C (-49°F) to -7°C (19°F) (Source). Cloud point refers to when the paraffin begins to crystallize and the fuel looks a little cloudy.

Biodiesel and petrodiesel is usually blended and this lowers the cloud point of biodiesel in the fuel considerably. In addition, additives are frequently added during cold weather that further lowers the cloud point.

When is biodiesel day celebrated?

National Biodiesel Day is March 18th, which is also Rudolf Diesel’s birthday. August 10th is International Biodiesel Day, a celebration of Rudolf Diesel’s prime model running for the first time on August 10, 1893.

Who invented biodiesel?

The diesel engine is defined by “any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder, where combustion and expansion actuate a piston.” Until petroleum was developed as a cheaper alternative, animal and vegetable oil was used. One of the first fuels used in the diesel engine was peanut oil, and thus biodiesel was born.

Can you use 100% Biodiesel even in the winter?

The answer is YES.  While biodiesel has a lower cloud point then petroleum diesel there is a technology by Optimus Technologies called the Vector System. This allows a truck to start on regular diesel until it gets up to temp and switch over to run on up to 100% biodiesel.  The City of Ames, Iowa is one success story of this technology.

The Sunflower oil in this project was purchased from Jedwards, International, Inc.  The common sunflower scientific name is Helianthus annuus. Sunflowers at late afternoon. Flowerheads facing East, away from the Sun.

First domesticated in the Americas the plant was exported to Europe in the 16th century and has become a staple as a cooking ingredient.  According Wildflower.org the common sunflower prefers full sun and well-drained soil. The plant grows up to 8 feet tall and has coarse hairy stems and leaves. The flowers are bright yellow surrounding a central maroon disk, that as it matures, holds the seeds and produces the oil.

The most known uses for sunflower seeds and its oils include; foods, cooking oils and butters. The pressed seed oil is useful for food and the resulting cake (matter left after the oil is harvested) is commonly used as animal food. One of the more interesting uses for the plant is, that it can produce a natural latex in its leaves. This latex can be used to produce hypoallergenic gloves.  The purpose of this post though is to discuss the possibility of biofuel created from sunflower seeds. Biodiesel magazine talks about both the pros and cons for this plant as a feedstock option:

“Because sunflower oil is priced higher than soybean and canola oils, its use as a feedstock for commercial biodiesel refining may be hindered in the U.S. market, according to the National Sunflower Association (NSA). However, there is an interest in the tall golden flowers because the seeds yield about 600 pounds of oil per acre, considerably more than soybeans, which produce a little over 500 pounds per acre.”

Because of the high value of the oil in other areas, using the oil for biodiesel can be cost prohibitive.  Higher concentrates of oil per acre can be vital as more efficiency in  biofuel production becomes necessary. According to Farm Energy, 15,000 to 25,000 plants per acre can be grown.  This means that a small or large farm can use this crop profitably or simply in the production of fuel for that farm.

Tung Oil

The Tung oil from this study was purchased from Sigma-Aldrich Co. The Tung tree, Vernicia fordii, is native to China and Vietnam.  This tree can be over 60 feet in height and is deciduous. Tung Tree at the Botanical Gardens Faculty of Science Osaka City University, Osaka, Japan According to Texas Invasive Species Institute:

“The bark is smooth, thin, and exudes white sap when cut. The leaves are simple, heart-shaped or with three lobes, and 6-10 inches long. The white flowers have 5 petals with red veins, and they bloom before the leaves emerge. The toxic fruits can grow up to 3 inches in diameter and are reddish green when fully developed.”

This tree is valued for its oil from the seeds.  Traditionally this oil was used in lamps and even as waterproofing on boats.  In more contemporary time this oil is used in varnishes and paint.  This value encouraged the importation of this tree. According to Texas Invasive Species Institute there was over 10,000 acres planted in the United States in 1927.  Cultivation of this tree has waned in the US after frosts and hurricanes destroyed many of the plantations.

This is one feedstock that isn’t part of the food vs fuel controversy.  The Tung tree and its oil is poisons to humans.  Even one seed from the fruit can be fatal, with symptoms including slowed breathing, vomiting and diarrhea.
