Switchgrass to EtOH - Costs

Article here.

Based on the $50-per-ton figure, and assuming a conversion efficiency of 80 to 90 gallons per ton, the farmgate production cost of cellulosic ethanol from switchgrass would be about $0.55 to $0.62 per gallon.

Those numbers aren't bad. They also feel that they'll be able to improve on those numbers given enough time to breed cultivars which will be more favorable for the cellulosic conversion process. It's pretty obvious at this point that corn is not going to be the silver bullet for the bioenergy movement, but switchgrass may possibly play a very significant role.
