How much does it cost to make cellulosic ethanol?
Currently production is done in demonstration quantities, therefore the price per litre is higher than it will be in a commercial facility. Cellulosic ethanol will be competitive with grain-based ethanol from a cost perspective. As more cellulosic ethanol plants are constructed, the cost of cellulosic ethanol will come down and is expected to be competitive with the price of rack (pre tax) gasoline.
