Is it more efficient to use biomass for heat, power or transportation?
With biomass electric generation, only 20-35% of the energy in forest products becomes useful electric power. 65-85% of the energy content of the wood is discarded as waste heat from the facilities.With biomass conversion to liquid fuels such as cellulosic ethanol, less then 40% of the energy in the feedstock is converted into usable fuel. But with biomass co-generation or biomass thermal, 80-92% of energy resources of forest products wind up as useful energy, displacing fossil fuels & carbon emissions.
