[RenewableEnergyAccess.com] Wood burning is the most common way to get energy from biomass, but Southern Company of Alabama has joined the ranks for energy companies researching biomass gasification. The two-year project began last fall in Wilsonville, Alabama, at the Power Systems Development Facility (PSDF) where Southern was co-firing switch grass with coal. Wood in various forms will be ground and fed into a high-pressure gasifier. Additional research will be performed on ways to clean the biomass-derived gas to meet stringent environmental requirements. The PSDF is a joint effort of the DOE’s National Energy Technology Laboratory, Electric Power Research Institute and the Tennessee Valley Authority. Southern Company manages the facility on behalf of the project participants.
