Keyes Low Carbon Ethanol

Aemetis owns and operates a 65 million gallon per year low carbon ethanol production facility located in Keyes, California. In addition to renewable fuel ethanol, the Keyes plant produces wet distillers grains, distillers corn oil, and condensed distillers solubles, all of which Aemetis sells to local dairies and feedlots as animal feed. Aemetis supplies 80 local dairies and approximately 100,000 cows with over 400,000 tons of animal feed annually. Through a partnership with Messer Gas, Aemetis also supplies over 140,000 tons of liquified CO2 to the beverage, food, and industrial sectors.

Current and planned upgrades include a [1.5 Mw size] solar microgrid with battery storage, Zebrex(C) ethanol dehydration unit, mechanical vapor recompression (MVR), and high-efficiency heat exchangers.

By converting the major processing equipment to renewable electricity, Aemetis expects to reduce the use of petroleum natural gas at the Keyes by 90% by 2025. Located above massive shale deposits, the Keyes facility is the future home to our carbon capture and sequestration facility.
