摘要

This paper analyzed potential and economics of carbon neutral methane in Japan. 8 to 10 billion Nm3 of carbon neutral methane can be produced from surplus electricity from 300 GW of solar photovoltaic and 100 GW of wind synthesized with CO_2 intensively emitted from biomass power plants, fossil fuel-fired power plants and large-scale industries, which is equivalent to 20% to 25% of the current city gas demand. Production cost of carbon-neutral methane is higher than hydrogen. However, supply (including production and delivery) cost of carbon-neutral methane is lower than hydrogen, as the carbon-neutral methane does not need new supply infrastructure.
