Bioconversion of solar energy to methane

Energy, 1977, vol. 2, issue 4, 365-373

Abstract: The purpose of this paper is to report the results of an investigation of the energy conversion efficiency of an aquatic based fuel-from-biomass system. The bases of the system are the biochemical conversions of solar energy to algal biomass to methane which is, in turn, used as auxiliary fuel for a fossil-fuel-fired steam-electric power plant. The alga used in the research was Anabaena flos-aque, a blue-green alga possessing many of the characteristics desired in an energy crop. The results of the research indicate that renewable methane can significantly reduce the imported fossil fuel requirement of the power station; that an overall efficiency of the conversion of solar energy to methane of one percent is attainable; and that energy inputs account for 12% of the methane fuel value.
