Biomass Energy - Focus on Wood Waste

Bringing you a prosperous future where energy is clean, abundant, reliable, and affordable Biomass and Alternative Methane Fuels (BAMF) Super ESPC Program Fact Sheet Biomass and … … Alternative Methane Fuels (BAMF) Super ESPC Program Fact Sheet Federal Energy Management Program Federal Energy Management Program Leading by example, saving energy and taxpayer dollars in federal facilities Thousands of large and small U.S. power plants use biomass fuels to produce more than 7700 MW of electricity. Wood waste is one of the …

Federal Energy Management Program Fact Sheet electricity in units ranging in size from 5 kilowatts to 75 megawatts. Another viable application for wood waste as a fuel is in the co-firing of conventional coal-fired boilers, which means using biomass as a supplementary energy source in high- efficiency boilers. Retrofitting most existing systems for co- firing requires relatively minor modifications and can significantly decrease emissions of sulfur dioxide and nitrogen oxide. Also, new developments such as gasification technologies offer dramatic improvements in process efficiency and could have a significant impact on the industry. Potential for Wood-Waste Projects in Federal Facilities The National Energy Technology Laboratory completed a resource assessment for FEMP to determine the potential for wood-waste projects at federal facilities. The assessment analyzed data reported by the wood products industry and indicates abundant opportunities for using this resource: • There are more than 12,000 sources of wood residues in the United States. • There is at least one substantial source of wood waste from manufacturing within 50 miles of virtually every federal facility. • For 75 percent of the larger federal facilities, there are 10 or more sources within 50 miles. • There are more than 4700 high-volume wood-waste sources within 50 miles of federal facilities. fluidized-bed combustion technology. Energy is generated this way in thousands of settings around the world using conventional, off-the-shelf equipment. The systems can be designed to produce heat, electricity, or both in combined heat and power systems. Wood-biomass systems produce Wood fuels can be cheaper than coal (dollars per Btu), and always emit less air pollution. Because the cost of disposal is avoided in some cases, wood waste may have a negative price. Energy projects using the abundant wood waste found on many federal lands can not only displace the use of fossil fuels but also reduce the risk of forest fires. Applications Given the age of the industry, it is not surprising that the technologies for converting wood to energy are well established. Whether for space heat, process heat, or electricity production, no other type of fuel has been used successfully in more types of system designs. In most industrial wood-to-energy applications, steam is produced in a boiler using standard stoker technology or newer The BAMF Super ESPC Federal agencies can use energy savings performance contracts (ESPCs) to finance their energy projects, allowing government facilities to reduce their energy use and costs without depending on Congressional appropriations to fund the improvements. Federal facilities worldwide can use the Technology- Specific Biomass and Alternative Methane Fuels (BAMF) Super ESPC, which offers financing and private-sector expertise specifically geared to using renewable BAMF resources….
