Aemetis Receives Authority to Construct Air Permits for MVR Project at California Ethanol Plant

Aemetis received Air To Construct permits for its mechanical vapor recompression (MVR) energy efficiency project at its 65 million gallon per year ethanol plant in Keyes, California.
Project completion is scheduled for Q2 2026, with construction expected to finish by mid-2026.
The MVR project is projected to increase annual cash flow from operations by $32 million through energy cost reductions, increased Low Carbon Fuel Standard credits, & higher Section 45Z tax credits.
Approximately $19.7 million in grants & tax credits have been secured from the California Energy Commission, Pacific Gas & Electric, & the U.S. Internal Revenue Service via Section 48C investment tax credits.
Upon operation, the system will reduce natural gas usage at the Keyes plant by approximately 80% & deliver a double-digit reduction in carbon intensity.
The Keyes ethanol plant has operated since 2011, supplying roughly two million pounds of animal feed daily to about 80 dairies while capturing 150,000 tons of CO2 annually for beverage-grade use.
This investment supports Aemetis' decarbonization strategy, complementing its dairy Renewable Natural Gas program which includes seven CARB LCFS pathways approved in June 2025.
Aemetis currently operates a network of biogas digesters processing waste from over 10,000 cows & is developing carbon sequestration & renewable diesel facilities in Riverbank, California.
