Review of electric hydrogen production technology combined with technology maturity analysis

In the context of the dual-carbon goal, China is strategically developing a green power system. Using electric power hydrogen production technology to promote the large-scale development of green hydrogen energy industry, which is a necessary condition for realizing the renewable and sustainable hydrogen economy. This paper assesses the electricity-to-hydrogen production technology by adopting the technology maturity analysis method, and summarizes the development maturity and current situation of various advanced hydrogen production technologies in China and internationally. By summarizing and comparing various water electrolysis technologies, analyze its application development potential and future research direction. Simultaneously, This paper also discusses the reasons and development defects that lead to the technology gap between China and the international advanced level. Eventually, it offers prospects for various technologies from the perspectives of scale and commercialization.
