The potential for boosting butanol as a biofuel is more promising thanks to USDA scientists and their partners. Work by the Agricultural Research Service (ARS) suggests that barley straw and corn stover – which are both agricultural byproducts – could be cost effective feedstocks for producing biobutanol. ARS is the USDA’s chief scientific research agency – and this work supports the USDA priority of developing new energy sources.
Gallon for gallon – biobutanol has 30-percent more energy than ethanol – and only around four-percent less energy than a gallon of petroleum-based gasoline.
