China has abundant renewable resources

which means great potential for green hydrogen production.However

renewable energy hydrogen production faces numerous challenges and is still in its infancy.This paper calculates the production and consumption capacity of green hydrogen and proposes a series of hydrogen technology development paths suitable for China.On the one hand

improving the performance of water electrolysis and optimizing the wind-solar-hydrogen integrated system is needed for hydrogen production.On the other hand

for green hydrogen consumption

the industrial sector

the transport sector

and the electric industry should highlight the green ammonium/methanol/SAF synthesis

hydrogen metallurgy

electricity-hydrogen conversion techniques and other techniques

vigorously supporting the action of renewable energy substitution.
