Development Status and Prospect of Hydrogen Production Technology by Renewable Energy and Its Main Equipment

Abstract

Purposes Hydrogen energy, as an efficient and clean secondary energy in the 21st century with its high heat value and extremely environmentally friendly combustion products, has become the most promising alternative energy source to replace traditional fossil fuels. The necessity of hydrogen development, promotion, and utilization under the dual-carbon goal of “carbon peaking in 2030 and carbon neutralvty in 2060” as well as the current hydrogen energy development policies and strategic layout in China are analyzed. Methods By investigating the research progresses and achievements of green hydrogen production technologies, the technology of hydrogen production by water splitting and its main devices are summarized, and the development status and trend of hydrogen production by water splitting and the related devices are reviewed. The research status of electrolytic cell and its important components (such as membrane electrode assembly, hydrogen tension bolt assembly and end pressure plate) and the main problems existing in key equipment are analyzed, and the future development trend of alkaline electrolytic cell and proton etchange membrane electrolytic cell are prospected. Conclusion This review provides a reference for the future development of hydrogen production equipment.
