| Popis: | Canada generates approximately 1.45 × 10 8 t of residual biomass per year, containing an estimated energy value of 2.28 × 10 9 GJ, which is equivalent to about 22% of Canada’s current annual energy use. Anaerobic digestion of these biomass residues using conventional technologies could generate 1.14 × 10 10 m 3 /year of CH 4 with a heating value of 4.56 × 10 8 GJ. Conversion of these residues using emerging technologies that favor the synthesis of H 2 and represses the synthesis of CH 4 could generate 1.47 × 10 10 m 3 /year renewable H 2 , with a heating value of 1.89 × 10 8 GJ. While CH 4 -production results in a larger amount of energy recovery, generating H 2 from waste biomass is a renewable alternative that could fuel the hydrogen economy. Additional research to further both the technical and commercial development of microbial bio-energy from biomass is warranted. |
