This course examines bioenergy technologies designed to replace fossil fuel-based heating systems and contribute to the production of renewable energy. It introduces solid, liquid, and gaseous biofuels, though focus is on biomass and anaerobic digestion. Topics include feedstock resources, processing, and characterization methods; systems for energy conversion by combustion/oxidation; policy; permitting; transportation; economics; nutrient recovery; carbon cycling; and life cycle analysis. Case studies focus on systems installed in Vermont. Successful completion of lab chemistry is recommended.
