The costs mentioned in the announcement would be for cellulosic ethanol made using enzymatic hydrolysis. This involves pre-processing the feedstock using recently developed enzymes in advance of sugar fermentation. Days longer, more complicated, with the price of the enzymes on top of that.

If the D.O.E. does not help fund a syngas fermentation deployment then there is something seriously wrong with the RFP process. The price per gallon is projected to be much lower than corn because there is no pre-process, no sugar fermentation per se, and no cost of enzymes. Plus, it is much faster and a much greater variety of cheaper feedstock can be used.


If they don't fund that, it's probably because the grain-farmers and ADM don't want it done (too much competition for them).
