Bioenergy to mitigate for climate change and meet the needs of society, the economy and the environment

摘要: Changes towards environmental improvementsare becoming more politically acceptableglobally, especially in developedcountries. Society is slowly moving towardsseeking sustainable productionmethods, waste minimisation, reduced airpollution from vehicles, distributed energygeneration, conservation of native forests,and reduction greenhouse gas (GHG)emissions. Modern biomass, when used tosupply useful bioenergy services, has arole to play each one theseenvironmental drivers at both the large andsmall scales.This paper describes recent developments inbiomass supply and technologies for itsconversion including biofuelsfor transport. It examines economic,environmental social benefits andidentifies barriers projectimplementation. Future opportunities forbiomass as a carbon (C) sink, C offsetand potential source renewablehydrogen are discussed.Whether or not project iseconomically viable, well being trulyrenewable, environmentallysound, determined mainly by sourceof biomass. The usingbiomass also valuable, though they areoften clearly presented proposingnew projects conductinganalyses existing plants. Employmentrates per MWh GJ exceed those whenusing fossil fuel supplies provide thesame energy service. `Ownership' bystakeholders local communities anearly stage development process isthe key successful developmentin order share benefits. Bioenergyhas significant global role inthe mitigation atmospheric GHG concentrations.
