Abstract：With the development of green hydrogen has become a global consensus, all countries' hydrogen production technology routes are based on the potential of local hydrogen sources and the future demand of hydrogen, showing the echelon development trend of low-carbon, clean hydrogen to renewable hydrogen. The development of hydrogen production by water electrolysis is the breakthrough of green hydrogen supply. This paper reviewed the technology of hydrogen production by water electrolysis, introduced the roadmap and technical target of hydrogen production by water electrolysis in the United States, Japan and Europe, deeply analyzed the development status of domestic water electrolysis technology, and quantified the gap with foreign technology level. On this basis, it puts forward the potential technology route of hydrogen production by water electrolysis in China. Finally, the levelized cost of low-carbon and clean hydrogen in China is analyzed, and predicted in 2020-2050. Reducing the leveled cost of hydrogen requires concerted efforts from multiple aspects such as technology and business model innovation, so as to play its role in energy transformation and deep decarbonization.
