Ethanol from grass at this time requires much different different process. Fermentation of grass does not yield significant alcohol. Manufactured enzymes are used, this is more expensive than corn alcohol. The left overs are not nearly as useful, not much feed value. More volume and weight to transport and long term storage is expensive too.
No free ride.
Nope no free ride, but instead of placing finding and effort into solving these issues we are continuing with a heavily subsidized loser of a program because it lines peoples pockets...
