Abstract

China has a huge potential for biomass utilization. Converting low-grade biomass into high-quality hydrogen and natural gas is of great significance in promoting the utilization of biomass resources and the achievement of carbon reduction goals. Based on the data of biomass collection, transportation, power generation, hydrogen production and gas production stages in China, this paper constructs a multi-chain hybrid whole-life process evaluation model for “electricity to gas” and comprehensively compares the energy consumption, carbon emission and cost of the two chains of “hydrogen production from biomass power generation” and “methane production from biomass power generation”. We comprehensively compare the energy consumption, carbon emissions and costs of biomass-to-hydrogen and biomass-to-methane technologies. Biomass natural gas is found to have significant advantages in terms of energy consumption, carbon emissions and economics compared to biomass hydrogen production. In order to promote the development of the biomass “electricity to gas” industry in China, this paper proposes that PEM electrolysis tanks can be used for hydrogen production, and the distance from the biomass feedstock collection to the hydrogen production chemical park should be optimized to reduce the whole-life-cycle cost. Biomass natural gas can buy time for the development of China’s hydrogen industry and infrastructure construction.
