As a long-term energy storage technology, hydrogen energy storage has a good development prospect. China's 14th five-year plan points out that hydrogen energy development is a long-term development strategy, in which the key points are to improve the conversion efficiency of hydrogen production by electrolysis, improve the design and manufacturing process of electrolyzer stack and electrode, and strengthen the coupling between renewable energy sources and hydrogen energy, so as to promote the realization of the targets of carbon peak and carbon neutrality. From the perspective of the 14th five-year plan and carbon peak and carbon neutrality, this paper first analyzes the development status of renewable energy in China and the generation of abandon wind, water and light, analyzes the feasibility of renewable energy for hydrogen production, and briefly introduces the classification of electrolyzer, the basic principle and research status of hydrogen production technology from electrolytic water. On the basis of the above, the hydrogen production technologies of wind power, photovoltaic power generation and wind solar hybrid multi energy coupling are summarized respectively. The research status of domestic and foreign scholars in this field is summarized, and suggestions and prospects for the development of renewable energy hydrogen production technology in China are put forward, It can provide reference for China to optimize renewable energy hydrogen production system and achieve the goal of decarbonization and emission reduction.
