China is rich in wind power resources

but has a huge amount of wind abandonment. Wind-hydrogen coupling energy storage technology is of great significance to reducing China's wind abandonment

improving wind power online quality

reducing energy and environmental pollution

alleviating energy crisis

building a green

environmental

friendly and sustainable power system

and promoting the transformation of economic growth mode. This paper introduces the research status of wind-hydrogen coupling energy storage technology at home and abroad

and summarizes the key technologies and difficulties to be solved in the research of wind-hydrogen coupling energy storage technology at present. Finally

combined with the development status of wind-hydrogen coupling energy storage technology in China

the application and development prospect of wind-hydrogen coupling energy storage technology in China is put forward.
