Application of biomass gasification technologies for electrical power production offers an opportunity to couple waste management with energy cogeneration. These applications call for reliable pyrolysis/gasification systems that are feedstock versatile and economically competitive, particularly at smaller biomass capacities. The Spouted Bed Gasifier (SBG) system being developed jointly by the University of Nebraska-Lincoln and Utilities Management Group has been designed specifically to address the niche for applications producing up to 10 MWe. This paper describes the use of the SBG system as the fuel conversion module in waste management - electrical cogeneration systems sized to fit a large institutional setting (a university), an animal production facility (cattle feed lot) and a food processing plant (sugar cane mill). The paper uses pilot plant data for wood gasification as the basis for biomass conversion performance to estimate capital cost and economic return for cogeneration in each of the settings. For institutional applications ranging from 0.15 to 5 MWe capacity, the capital investment ranges from $650,000 to $7,000,000. Payback times range from 3 to 6 years.
