Cellulosic ethanol

Pilot Plant Gasification Technology Traces to GM Ohio Foundry

MADISON, Pa., 2008-04-25 – General Motors Corp.’s role in helping Coskata Inc. bring its next-generation cellulosic ethanol to market traces back a quarter of a century to technology developed for a GM iron foundry in northwest Ohio.

Coskata announced Friday that its pilot plant will be located at the Westinghouse Plasma Center in Madison, the current site of a pilot-plant gasifier.

Gasification is the first step in Coskata’s process to make ethanol out of practically any renewable source. Plasma torches are used to super heat source material, such as agricultural and municipal solid waste, to 1,600 degrees Fahrenheit, which creates a synthesis gas comprised of carbon dioxide and hydrogen.

Sebring, Fla., January 29, 2008 – In a technological breakthrough in both the renewable fuels arena and racing, KL Process Design Group (KL) of Rapid City, SD, will supply the American Le Mans Series with cellulosic E85 racing ethanol for the 2008 season. The fuel, produced from waste wood, will be used for the first time during the season opener — Mobil 1 Twelve Hours of Sebring on March 15, 2008. Consumer E85 is a blend of 85 percent ethanol and 15 percent gasoline. Cellulosic ethanol is produced from biomass such as wood waste, switchgrass or citrus. Corvette Racing will be the first team to use the cellulosic-based flex-fuel ethanol in competition.
