A new study indicates that cellulosic ethanol from corn residues is not better than gasoline.
From the Associated Press, a study in Nature Climate change says cellulosic ethanol from corn residues produces 7% more GHG than gasoline. Dupont has a $200 million plant coming on line that will do this. And, of course, there is some disagreement with the study which was done under an EPA grant.
Is this another nail in the cellulosic ethanol coffin?
