Energy production with hyperthermophilic organisms

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 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.

1 . A method comprising:
 a) providing a biomass selected from the group consisting of a food waste biomass and a sewage sludge biomass and a population of hyperthermophilic  Thermatoga  spp.;   b) degrading said biomass in the presence of said population of hyperthermophilic  Thermatoga  spp. at a temperature of above 80° C. under conditions such that degradation products are produced.   
     
     
         2 . The method of  claim 1 , wherein said degradation products are selected from the group consisting of hydrogen and acetate. 
     
     
         3 . The method of  claim 1 , further comprising the step of converting said degradation products into energy. 
     
     
         4 . The method of  claim 2 , further comprising using said hydrogen in a fuel cell. 
     
     
         5 . A method for reducing carbon dioxide emissions comprising:
 a) providing a biomass selected from the group consisting of a food waste biomass and a sewage sludge biomass and a population of hyperthermophilic  Thermatoga  spp.;   b) anaerobically degrading said biomass in the presence of said population of hyperthermophilic  Thermatoga  spp. at a temperature of above 80° C. to produce substrates for energy production;   c) producing energy from said substrates, wherein carbon dioxide emissions are reduced as compared to aerobic degradation of said biomass materials.   
     
     
         6 . A method for generating carbon credits comprising:
 a) providing a biomass selected from the group consisting of a food waste biomass and a sewage sludge biomass and a population of hyperthermophilic  Thermatoga  spp.;   b) anaerobically degrading said biomass in the presence of said population of hyperthermophilic  Thermatoga  spp. at a temperature of above 80° C. to produce substrates for energy production,   c) producing energy from said substrates under conditions such that carbon credits are generated.
