Zubrin biomass to electricity process

Robert Zubrin and Mark Berggren both of Colorado were recently issued United States Patent 7,937,948 for a process for converting biomass into electricity without releasing CO2. The patent is entitled “Systems and methods for generating electricity from carbonaceous material with substantially no carbon dioxide emissions.” The process essentially involves contacting the biomass with superheated steam to generate a mixture of CO2 and hydrogen. The gas mixture is passed through a condenser then a methanol separator to remove the CO2. The remaining hydrogen is combusted to drive a turbine without the production of CO2. The CO2 that was removed in the methanol separator is either sequestered by conventional means or used in another process. In one embodiment the steam reformation of the biomass occurs in a fluidized bed reactor.
