General Motors today announced their second equity investment in a developer of cellulosic ethanol technology in recent months. The automaker is buying into Mascoma Corp. Mascoma has developed a single-step cellulose to ethanol process that apparently requires fewer enzymes and other additives. Mascoma has proprietary microbes that are used in its Consolidated Bioprocessing (CBP) technology. The CBP process can convert most forms of biomass such as straw, wood, paper pulp, and agricultural waste into liquid fuel. So far, Mascoma has received more than $60 million in federal and state grants for their work. To date Mascoma has been testing their technology in the lab with a demonstration plant due to come on line later this year in Rome, NY. GM President Fritz Henderson is not disclosing how much the automaker is investing. Earlier this year GM invested in Illinois-based Coskata. GM is holding a conference call later this afternoon where we will hopefully get more details. We do know that Mascoma has been trying for a while to have the first cellulosic ethanol plant up and running, with projects announced in Tennessee, New York state and Michigan.
