Feasibility of an energy conversion system in Canada involving large-scale integrated hydrogen production using solid fuels

摘要

A large-scale hydrogen production system is proposed using solid fuels and designed to increase the sustainability of alternative energy forms in Canada, and the technical and economic aspects of the system within the Canadian energy market are examined. The work investigates the feasibility and constraints in implementing such a system within the energy infrastructure of Canada. The proposed multi-conversion and single-function system produces hydrogen in large quantities using energy from solid fuels such as coal, tar sands, biomass, municipal solid waste (MSW) and agricultural/forest/industrial residue. The proposed system involves significant technology integration, with various energy conversion processes (such as gasification, chemical looping combustion, anaerobic digestion, combustion power cycles-electrolysis and solar-thermal converters) interconnected to increase the utilization of solid fuels as much as feasible within cost, environmental and other constraints. The analysis involves quantitative and qualitative assessments based on (ⅰ) energy resources availability and demand for hydrogen, (ⅱ) commercial viability of primary energy conversion technologies, (ⅲ) academia, industry and government participation, (ⅳ) sustainability and (ⅴ) economics. An illustrative example provides an initial road map for implementing such a system.
