In order to accelerate the realization of the “Paris Agreement” global warming temperature control goals and to achieve carbon emission reduction and green sustainable energy development, countries around the world are actively exploring and developing new energy utilization technologies. This paper takes China as an example to study and analyze the methanation path based on Power-to-X technology. The results show that:①China’s potential for hydrogen production from renewable energy in the future, as well as the introduction of CO2 capture technology for thermal power plants and other sectors for carbon emission reduction and resource utilization, all have good potential, and both can provide sufficient raw materials for the methanation process;②Methanation production by providing green hydrogen and capturing and recovering carbon dioxide is in line with the goals and requirements of the new generation of energy systems for sustainable development. This technological path is actually helpful for delaying global warming and realizing the reduction and resource utilization of renewable energy curtailment in CO2. At the same time, in the future, relying on the synergy of technology and policy to continuously increase the scale of the system to reduce the overall cost, it is expected to achieve large-scale applications.
