More environmental news from GM as it invests in a biofuel start, Coskata. The company is looking to commercialize a process to bring cellulose-based ethanol by 2011. Currently switchgrass and wood chips are the main materials being used to produce cellulose-based ethanol. GM claims that the production of the company’s ethanol is less than $1 a gallon to produce, about 1/2 that of producing gasoline. This investment goes in hand with its push with hybrid vehicles, particularly as it pushes more consumers toward E85 biofuel (85% ethanol and 15% gasoline mix) in its FlexFuel vehicles.
