With the finalization of this new supply contract, Gevo will initially supply Air Total with ATJ fuel from its demonstration facility in Silsbee, Texas and later from Gevo’s expanded Luverne, Minnesota plant which is expected to be constructed over the next several years. The Silsbee project can produce up to 50,000 gallons of ATJ per year.
million for five projects to develop advanced biofuels and bioproducts that will help drive down the cost of producing gasoline, diesel, and jet fuel from biomass.

A US-wide county-level study comparing lifecycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) has found that PEVs can have larger or smaller carbon footprints than gasoline vehicles depending on regional factors and the specific vehicle models being compared.
