Although the number of US ethanol plants fell in 2026 compared with a year ago, production stayed steady; however, a drop in biodiesel plants reduced production, the Energy Information Administration reported Thursday.
In its US Biofuels Plant Production Capacity Report, the EIA said US ethanol plants totaled 189 as of Jan. 1, down from 191 a year ago. The plants' combined production totaled 1.20 million barrels per day, the same as last year. In 2025, US plants produced 18.48 billion gallons per year.
The number of biodiesel plants in 2026 totaled 45, down from 48 a year ago. This year's production totaled 128 million b/d, down from 130 million b/d a year ago. In 2025, annual biodiesel production totaled 1.98 billion gallons.
The number of renewable diesel and other biofuels plants in 2026 remained at 19, unchanged from the previous year. Production capacity in 2026 totaled 324 million b/d, up from 308 million b/d last year. In 2025, US renewable diesel production totaled 4.72 billion gallons.
