U.S. Biofuels Production Capacity Growth Slowed in 2024 - CleanTechnica

The growth of U.S. biofuels production capacity significantly slowed in 2024, with an overall increase of only 3% from the start of 2024 to 2025. This deceleration was primarily driven by a marked slowdown in renewable diesel and other biofuels capacity additions, which grew by just 391 million gallons per year—less than one-third of the growth seen in 2022 and 2023. Notably, only two renewable diesel capacity expansions occurred in 2024, both in California: Phillips 66’s Rodeo refinery conversion, increasing capacity to 767 million gallons per year, and a new Renewable Fuels LLC plant in Bakersfield with 138 million gallons per year. However, these gains were partly offset by the closure or cessation of renewable diesel operations at four other facilities, reflecting shifts in biofuel and petroleum refining margins since 2020. In contrast to renewable diesel, biodiesel production capacity slightly declined in 2024 due to the closure
