Abstract:

Water electrolysis for hydrogen production powered by green energy such as PV and wind power is an important technical rout to realize the national energy strategy of carbon neutrality and carbon peaking. Nevertheless,the volatility of wind power and PV seriously affects the dynamic adaptability and operational reliability of the hydrogen production system based on water electrolysis. By expounding the characteristics of the hydrogen production technology powered by wind-PV complementary systems,and analyzing the mechanism and economy of this technology,an efficient and reliable technical rout of water electrolysis for hydrogen production powered by fluctuating wind power and PV is conceived,to extricate from the predicament in water electrolysis for hydrogen production. There are three key steps in the realization path, system configuration optimization, stable operation and service life extension. Targeting at the system service life management, the safe, reliable and economic operation of the water electrolysis system for hydrogen production powered by PV and wind power lays a favorable foundation for the development of wind-PV-hydrogen industry chain.

Key words: carbon neutrality, integrated energy, wind power generation, PV power generation, PV-wind complementary system, water electrolysis for hydrogen production, fluctuating power supply, service life extension, wind-PV-hydrogen industry chain
