Abstract:

Campbell et al. [Report in Science 2009 (May 22), 324, 1055] analyzed two scenarios where bioenergy crops were used for transportation – (1) cellulosic ethanol production by biorefineries for internal combustion engines and (2) bioelectricity generation by power stations for electric motors. Their study suggests the latter approach offers more efficient energy utilization than the former. We argue that the evaluation of a transportation system must be based on complicated metrics rather than only one or two factors. We suggest another out-of-the-box solution biomass carbohydrate-to-hydrogen-to-electricity as a key component of the future transportation sector.
