In Washington, EnergyNow reports U.S. biodiesel producers are struggling to expand output fast enough to meet the Trump administration’s biofuel ambitions. In May, plants operated at roughly 77% of capacity, below the EPA’s assumption of 90% utilization for its mandates. Producers generated 736 million biomass-based diesel RINs, compared with about 915 million needed that month, raising concerns about compliance costs and supply. The shortfall has prompted the American Fuel & Petrochemical Manufacturers to sue and urge lawmakers to reconsider the 2026 mandates. The gap highlights challenges in scaling production despite stronger policy support.
