General Motors and Coskata today announced that a pilot plant for cellulosic ethanol will be built in Madison, Pennsylvania. The plant will located adjacent to the Westinghouse Plasma Center in Madison. The plasma torches that Coskata will be using for their gasification process are based on technology that was developed by GM and Westinghouse in the early eighties. At that time the companies developed a plasma furnace used to melt raw materials for cast iron production at GM foundries. The first production application was at a GM foundry in Defiance OH in 1989.

Coskata is using the same plasma torch technology to heat biomass materials to over 1,600 degrees Fahrenheit. That temperature is sufficient to convert almost any organic matter into a gas that is an intermediate ingredient in Coskata's process for producing cellulosic ethanol. Coskata's pilot plant will use Westinghouse Marc-3 plasma torches while the commercial scale plant will use larger Marc-11 torches. The pilot plant will be in operation in Q1 2009 with the first commercial plant following in 2011.
