Biomass made into electricty produces more miles than bio-ethanol

Posted by Lindy on May 11, 2009

Electric vehicles using biomass converted into electricity travelled 81 percent farther per area of cropland than vehicles with internal combustion engines running on  ethanol, researchers in California found.

A small sport utility vehicle could do 36,000 km on the energy produced from a hectare of switch-grass converted into ethanol. But converting that biomass into electricity allowed a battery-powered SUV to get 56,000 km on the highway, the study published in Science magazine said.

But we do not yet produce enough switch grass to run power stations nor is the development of 2nd generation  bio-fuels sufficiently advanced for this to be a current reality. But certainly the idea that electric cars could prove to be more efficient than those run on bio-fuels is something to bear in mind.
