Goldman Sachs invested $30 million in Iogen Corporation, the leader in cellulose ethanol technology. Iogen is the only company currently operating a demonstration facility that converts agricultural waste like straw and corn stalks into ethanol. The funds will allow Iogen to accelerate its commercialization program. A joint USDA and DOE study found that US land resources could produce enough biomass to displace 30% of current US gasoline consumption through cellulose ethanol.
