![]() ![]() This overview focuses on woody biomass used for generating electricity at a commercial-scale facility rather than a utility-scale project. In Woodland, California, a generation station uses wood from the agricultural industry. In addition, most other types of biomass can be converted into bio-oil through pyrolysis, which can then be used in boilers and furnaces. Very wet wastes, like animal and human wastes, are converted into a medium-energy content gas in an anaerobic digester. Corn stover and wheat straw residues are baled for combustion or converted into a gas using an anaerobic digester. Typically, woody biomass such as wood chips, pellets, and sawdust are combusted or gasified to generate electricity. Anaerobic digestion produces a renewable natural gas when organic matter is decomposed by bacteria in the absence of oxygen.ĭifferent methods work bet with different types of biomass. Pyrolysis yields bio-oil by rapidly heating the biomass in the absence of oxygen. Gasification produces a synthesis gas with usable energy content by heating the biomass with less oxygen than needed for complete combustion. Other options include gasification, pyrolysis, and anaerobic digestion. ![]() The most common is direct combustion of biomass material, such as agricultural waste or woody materials. ![]() The term biomass encompasses a large variety of materials, including wood from various sources, agricultural residues, and animal and human waste.īiomass can be converted into electric power through several methods. Biomass is used for facility heating, electric power generation, and combined heat and power. ![]()
