Abstract
The present invention relates to the field of degradation with hyperthermophilic organisms, and in particular to the use of hyperthermophilic degradation to produce heat and energy rich components including hydrogen and ethanol from a biomass. In some embodiments, a biomass is fermented in the presence of hyperthermophilic organisms to produce heat. The heat is used to heat a liquid which is used directly in a heat pump or radiant heat or to produce electricity or drive a steam turbine. In some embodiments, acetate is utilized as a substrate to produce energy by methanogenesis.
