Biomass for Electricity Generation | WBDG - Whole Building

Boiler fuel can include wood chips, pellets, sawdust, or bio-oil. Steam from the boiler is then expanded through a steam turbine, which spins to run a generator and produce electricity. In general, all biomass systems require fuel storage space and some type of fuel handling equipment and controls.

Annual emissions of CO 2 in UNFCCC reporting format (In Mt = million tonnes).. For CO 2 only, the (national) totals do not include emissions from biomass burning or emissions or removals from land-use change and forestry (LULUCF - CFR 5). The energy sector (CFR 1) is responsible for energy-related emissions, such as those arising from fuel combustion activities and fugitive emissions from fuels.

The Effect of Biofuel Production on Greenhouse Gas

Biofuels can reduce the consumption of fossil fuels and thus reduce carbon dioxide emissions, because biofuels are carbon neutral. More specifically, the carbon dioxide that is emitted when a biofuel is burned merely returns to the atmospheric carbon dioxide that was taken into plants from the atmosphere by photosynthesis.
