On U.S. Oil

How can US Oil transition to "Next Gen Fuels" when oil has been its main business and is even in its name?


We are called US Oil, but in reality we are an energy company that has recognized the imperative and embraced the opportunity to begin the transition from fossil fuels. The market demands it. The technology is there. Most critically, the realities of climate change are upon us.

We would like to begin transforming some of our facilities and developing products that help reduce greenhouse gas emissions in the form of Next Gen fuels. Next Gen fuels are transportation fuels (e.g. Renewable Diesel, Renewable Jet fuel) derived from sustainable feedstocks (the raw materials transformed into fuel products) like vegetable oils, greases, algal oil and waste oils.

What is "clean" about your business?


You cannot be headquartered in this area without recognizing the importance of being cleaner and greener wherever you can. We share the values of our community when it comes to protecting the environment. Specific things that we do differently are:

On Next Gen Fuels (Bio Jet, Bio Diesel)

What are Next Gen Fuels?


Next Gen Fuels are transportation fuels (Jet, Diesel) derived from sustainable feedstocks (the raw materials transformed into fuel products) like vegetable oils, greases, algal oil and waste oils.

What other names are used with Renewable Diesel/Jet?


The generic title is Hydrogenated Esters and Fatty Acids (HEFA) Diesel and Hydrogenation Derived Renewable Diesel (HDRD).

There are existing company trademark names for the process of creating HDRD or HDRJ (Hydrogenation-Derived Renewable Jet)

Where are the statistics proving that what you want to do is better for the environment?


Most significantly, Renewable Diesel and Jet fuel reduces greenhouse gas emissions by 65-80%.

We are an energy company that has recognized the imperative and embraced the opportunity to begin the transition from fossil fuels.

The process to make this transition has three primary steps:

Is Renewable Diesel (HDRD) the same as Bio Diesel?


No, it is not the same as the traditional Bio Diesel, and is incorrectly referred to in some cases as 2nd Gen Bio fuels. Bio Diesel and Renewable Diesel are derived from similar feedstocks such as plant oils, animal fats, and waste greases. However, the processing of these feedstocks makes a much different product. Among other qualities, Renewable Diesel is more stable. As a result, it can be blended with traditional diesel in any proportion, whereas Bio Diesel is normally limited to 20%.

Is the performance of Renewable Diesel basically indistinguishable from Diesel derived from Fossil Fuels?


Yes. Renewable Diesel fuel is produced from renewable feedstock that is predominantly hydrocarbon and is largely indistinguishable from Diesel. Renewable diesel reduces tailpipe pollution and has a lower carbon intensity (varies on feedstocks) of traditional diesel along with lower particulates and reduced nitrogen oxide.

What are the various feedstocks used in Renewable Diesel?


Can you convert the existing refinery to only process renewable products instead of crude oil?


No. Given the variability of the feedstocks, the unique specific processes for the conversion, and different metallurgy (properties of metals) requirements, an integrated separate facility is required. Additionally, to complete Next Gen Fuels, the renewable material must be blended in with traditional fuels, which is a different process than traditional refining.

How much cleaner are renewable fuels compared to traditional fuels?


It varies, but each shows reduction in greenhouse gasses (GHG). One recent analysis using Camelina and Jatropa (vegetable oils) as feedstocks showed a 65%-80% reduction in GHGs.

Where else is this technology being applied in the world?


From Singapore to Rotterdam, and even in our own backyard.


Can you use 100% Renewable Jet as a replacement for Jet derived from Fossil Fuels?


No. Currently, Renewable Jet fuel requires it to be blended with traditional fuel. The blend is limited to 50% in aircraft fuel systems because proportions well in excess of 50% can cause O-rings and other similar materials to shrink, resulting in fuel leaks.

The Transition from Fossil Fuels

Why Renewable Fuels?


The market demands it. The technology is there. Most critically, the realities of climate change are upon us. Next Gen Fuel is also affordable, reliable, and efficient, and offers a promising pathway toward safer energy for the future.

As a business, Next Gen Fuels give us additional product offerings to meet increasing demand as well as the ability to develop new partnerships with customers, among other things.

As a neighbor and longtime part of our local community, the development of Next Gen Fuels gives us the opportunity to significantly reduce CO2 emissions, it lessens our dependence on traditional fossil fuel source materials and it reflects our values for clean air and water in the region where we live, where we work and where we are headquartered.

Producing Next Gen Fuels (the facilities, the process)

What is the production process of Renewable Diesel/Jet?


It is very similar to fossil fuels in the refining sector.

*Hydrotreating is an established refinery process for reducing Sulphur, nitrogen and aromatics while enhancing cetane number, density and smoke point

**Transesterfication involves vegetable or animal fats and oils being reacted with short-chain alcohols (typically methanol or ethanol)

Are there biproducts of Next Gen Fuel production, and if so, how are they managed?


Sulfur is a byproduct of the renewable jet and diesel production process. Fortunately, refineries have the capability to capture this by-product and convert it to elemental sulfur, which can be used in fertilizer manufacturing or other chemical manufacturing processes.

Safety

How do you transport Next Gen Fuels?


Renewable Diesel and Jet when blended are transported in the same manner as current fossil fuel derived transportation fuels.

Is transportation of Next Gen Fuels safe?


All the precautions taken to transport traditional fuels safely, including rail, are used to transport Next Gen Fuel. For example, US Oil crude railcars are modern, jacketed, insulated, and thermally protected, employing full-height head shields, as well as a compliment of safety valves. Additionally, US Oil is regulated by twelve separate local, state and federal agencies, including the EPA, the U.S. Coast Guard and the Pipeline and Hazardous Material Safety Administration, and we participate with regional first responders in drills/exercises that prepare and practice response to an accident on a regular basis. We are committed to collaborating with community and elected leaders and input from our neighbors that helps us do our part in protecting public safety, while also maintaining clean water and air in this region.
