bp – Cherry Level refinery turns feedstock into renewable diesel gas, Right here’s how.
In some ways, the world is clamoring for extra low-carbon power.
That’s why bp is aiming to spice up biofuel manufacturing to almost 50,000 barrels per day globally, by 2025. In Washington state, bp’s Cherry Level refinery is likely one of the most dynamic locations the place work towards this intention is taking form.
Practically two hour’s drive from Seattle and simply south of the US-Canadian border, Cherry Level is the Pacific Northwest’s largest refinery, able to processing roughly a quarter-million barrels of crude oil every day on common – a lot of it from North America.

Since opening in 1971, Cherry Level has primarily produced conventional fossil-based fuels. The truth is, it gives a lot of the jet gas used on the Seattle-Tacoma and Vancouver worldwide airports.
In 2018, Cherry Level started producing renewable fuels with decrease lifecycle emissions than conventional fuels. A part of this was pushed by coverage: Washington state, California, Oregon and British Columbia have all handed initiatives to scale back the carbon depth of transportation fuels by as much as 20%. All of this has set the stage for accelerating the manufacturing of biofuels, partly by way of one thing known as “co-processing.”
In co-processing, the refinery makes use of standard crude oil together with biomass-based feedstocks, like meals waste and beef tallow, to provide a blended gas. It’s additionally one of the vital environment friendly methods to scale back a gas’s lifecycle emissions: co-processed renewable diesel can scale back the gas’s carbon depth by as much as 30% in contrast with common, fossil fuel-created diesel.
Amber Russell, bp’s SVP for refining, stated:
We’re excited that Cherry Level continues taking steps in the direction of a decrease carbon future.
“This work reveals the essential position refining can play in serving to each bp and the world to succeed in web zero.”
Cherry Level is tapping into its current infrastructure to assist meet this demand: The refinery’s processing unit, which already makes fossil-based diesel, has been capable of transition over to co-processing.
bp is concerned in every stage of the method, from feedstock to finish product. This lends the corporate large technical and business benefits as a result of we select and buy the feedstock, then course of, distribute and promote the gas.
Cherry Level now has the aptitude to co-process greater than 7,000 barrels of renewable diesel gas every day, about 2.6 million barrels annually. And it’s a drop-in gas, which means truck drivers can use it with none modifications to the fleet.
Nigel Dunn, bp’s SVP for biofuels progress, stated:
Biofuels have the potential to be one of the vital cost-effective de-carbonization choices accessible.
Listed below are the fundamentals of how co-processing works:
1. Determine the proper feedstock
bp’s co-processing journey begins with selecting a feedstock. When Cherry Level first co-processed in 2018, the refinery began with beef tallow – which comes from slaughterhouses and rendering amenities. At this time, Cherry Level additionally co-processes used cooking oil, canola oil, soybean oil and byproducts from the ethanol trade, amongst different supplies.
Meaning we will change issues on our finish, just like the renewable sources, however our clients don’t have to vary a factor.
bp’s buying and selling workforce works with the refinery to decide on the very best feedstock primarily based on its economics. Every kind of feedstock trades at a unique worth. They take into account the logistics of getting the feed to the refinery, in addition to state and federal incentives. From there, the refinery considers how greatest to course of the chosen feedstock.
2. Gas is processed – and impurities eliminated
One of many refinery’s processing models – its hydrotreater – processes the renewable feedstocks alongside the traditional petroleum feedstocks.
One pipe brings within the conventional fossil feedstock, whereas one other brings within the tallow or different bio-feedstock. Each fuels are then combined earlier than the system provides hydrogen at an elevated temperature to take away impurities – largely sulfur.
The top product is a high-quality gas that’s chemically similar to a diesel product made solely by way of fossil fuels. In different phrases, it has the very same efficiency. However the main distinction is that this gas has decrease lifecycle carbon emissions.
Beef tallow, used cooking oil, animal fat and byproducts from the ethanol trade are all waste merchandise. Much like recycling, bp repurposes them right into a usable gas.
By combining the biofeedstock, and conventional fossil gas to make co-processed renewable diesel, bp reduces the quantity of upper carbon fossil gas, whereas growing the quantity of decrease carbon bio feedstock to make its diesel.
3. Distribute – and promote – low-carbon gas
bp makes use of barges, ships, pipes, trains and vehicles to distribute its gas everywhere in the US.
For those who drive a diesel automotive or truck and refill at a bp model – maybe ampm or TravelCenters of America (TA) on the West Coast – you could be shopping for renewable diesel produced at Cherry Level.
bp’s merchants take into account completely different costs, credit and shops to seek out the perfect dwelling for its renewable diesel. Some renewable diesel is bought to our bp-owned websites whereas some is bought within the market to non-bp retailers.
When bp sells co-processed renewable diesel gas at company-owned manufacturers like TravelCenters of America, it’s a key instance of an built-in power firm in motion. It’s additionally one of many causes bp purchased TA in 2023 – together with the truth that the TravelCenters model offers the corporate entry to 300 places strategically positioned alongside main US highways. The places are giant, typically 20-acre plots, that fulfill the wants of truck drivers, largely, but additionally contains full-service eating places, truck service facilities, laundry amenities, pet areas and extra.
