Large-scale hydrogen production technology from renewable energy such as solar power and wind power has become an important pathway for the consumption of renewable energy and the achievement of “dual carbon” goals. The policies and strategic layout of hydrogen energy at home and abroad are introduced

and the advantages and technical bottlenecks of water electrolysis technologies are analyzed. Moreover

the classification

coordination control optimization and energy management of large-scale renewable energy hydrogen production systems are sorted out. In view of the current development status of hydrogen energy in China

a brief analysis of the current installed capacity and the cost is performed

providing a reference for the construction of green hydrogen production system and the clean substitution of terminal energy in China.
