The U.S. Energy Information Administration released data on July 21 forecasting that U.S. renewable diesel production capacity will reach 5.1 billion gallons per year (330,000 barrels per day) by 2024, up from an estimated 600 MMgy (38,000 barrels per day) in 2020. The agency said growing targets for state and federal renewable fuel programs and incentives for renewable diesel production are driving the expected expansion.

According to the EIA, much of the expected capacity increase will come from retrofitting idle petroleum refineries. The agency offers Marathon Petroleum’s refinery in Martinez, California, and the Phillips 66 refinery in Rodeo, California, as two examples of oil refineries that are currently converting to renewable diesel production.

Currently, nearly all U.S. imports of renewable diesel enter the country in the West Coast where the fuel is used to meet Low Carbon Fuel Standard targets in California. Most existing U.S. renewable diesel capacity, however, is located in on the Gulf Coast near existing oil refineries. Moving forward, the EIA predicts the majority of new U.S. renewable diesel capacity will be built on the West Coast to serve nearby low carbon fuel markets, while the remainder will likely be built on the Gulf Coast to capitalize on existing refinery infrastructure.

Based on its capacity estimates, the EIA said it predicts renewable diesel production capacity could represent 20 percent of total diesel production on the West Coast by 2024 and 4 percent of total estimated diesel production capacity on the Gulf Coast. Across the entire U.S., renewable diesel capacity would account for 5 percent of total diesel production capacity in 2024.
