The biofuels industry has been unable to convert millions in government research subsidies into an effective, large-scale cellulosic fuel conversion solution, according to this piece from Technology Review. Instead, one producer is switching back to corn as a primary feedstock, and is further buffering its risks by producing butanol rather than ethanol. Government mandates have not convinced fuel buyers to switch to biofuels, and a reliable supply of cellulosic feedstocks is not yet in place. Nevertheless, cellulosic biofuels could go a long way to reducing fossil fuel consumption. Is this the time for a biofuel Manhattan Project?
