Abstract: Green hydrogen produced by renewable power such as wind power and photovoltaic power meets the requirements of energy development in the new era. Renewable power is characterized by intermittence, fluctuation and randomness, which puts forward higher requirements for water electrolysis technology. The key to the development of electrolytic water technology lies in materials. This topic reviews the development of hydrogen production technology by alkaline water electrolysis and proton exchange membrane pure water electrolysis from the aspects of oxygen evolution electrocatalyst, electrolyte, membrane material and diffusion layer material, and introduces the application and development status of hydrogen production technology by renewable power, and analyzes the existing technical problems, and puts forward some suggestions on the research and development of electrolyzed water and green hydrogen technology by renewable power for the future.

Key words: hydrogen energy, green hydrogen, hydrogen production, alkaline water electrolysis, proton membrane water electrolysis, renewable power
