The American energy manufacturing company, Phillips 66, has announced plans to convert its San Francisco refinery to produce renewable fuels which will make it the largest in the world, according to a press release.

After undergoing the conversion, the refinery will no longer produce fuels from crude oil, but rather produce fuel from used cooking oil, fats, greases, and soybeans.

Greg Garland, chairman and CEO of Phillips 66, said, “Phillips 66 is taking a significant step with RodeoRenewed to support demand for renewable fuels and help California meet its low carbon objectives.”

The project, called “Phillips 66 Rodeo Renewed”, is expected to produce 680 million gallons annually of renewable diesel, renewable gasoline, and sustainable jet fuel. This will be in addition to the production of renewable fuels from an existing project in development. With the two operations combined, the plant would produce in excess of 800 million gallons a year of renewable fuels, transforming it into the world’s largest facility of its kind.

The plant is expected to produce renewable fuels by early 2024.
