Zero Carbon New Energy Consumption System based on Electrolytic Water to Hydrogen, Biomass Combustion and Methanol Synthesis/Reforming

To resolve the problem that hydrogen energy is not easily stored and transported, a zero-carbon new energy consumption system based on electrolytic water to produce hydrogen, biomass combustion technology and methanol synthesis/reforming is proposed. The system uses renewable electricity generated from wind, geothermal energy and photovoltaic to provide electricity for electrolysis of water. The hydrogen produced by the electrolysis tank acts as a feedstock for methanol synthesis, the oxygen produced by the electrolyzer is used for biomass combustion, and the carbon dioxide from the biomass combustion plant is used to synthesize methanol in the methanol synthesis plant with the hydrogen produced by the electrolytic water, and the generated methanol is transported by vehicle to a methanol reforming plant in a remote location. The carbon cycle of the system was analyzed by energy analysis and economic analysis. The results show that the comprehensive energy efficiency of the system is 34.90%. When the electricity price is 0.2 yuan /kW•h and the hydrogen price is 50 yuan /kg, the DPP is 1.04 years, and the NPV is 379532200 Yuan.
