The replacement of hydrogen production from fossil fuels with renewable energy-based hydrogen production is the primary path for achieving green and low-carbon transformation in the future industrial field.Alkaline electrolysis technology currently dominates water electrolysis hydrogen production in China,and PEM electrolysis technology suitable for volatile new energy sources holds better development prospects.An analysis is conducted on the competitiveness of green hydrogen from the perspectives of economy and carbon emissions,it is thought that the current cost of green hydrogen remains high in China.As the cost of new energy electricity declines and the cost of carbon emission rises in the future,green hydrogen will gradually assume a crucial role in Chinas energy system.The current status and trends of green hydrogen development are introduced,and the main problems in the green hydrogen industry are analyzed.It is pointed that there has been an acceleration of green hydrogen chemical projects in China in recent years.Nevertheless,considering the process of industrial decarbonization comprehensively,it is essential not to blindly accelerate the industrial application process of green hydrogen.Meanwhile,national-level support policies for green hydrogen preparation and industrial consumption should be issued promptly along with accelerated progress in constructing relevant standard systems to achieve sustainable and healthy industry development.
