氢能作为清洁无碳、灵活高效的二次能源和工业原料，具有广阔的发展前景。虽然单独的电解水制氢、储氢和供氢技术都已发展相对成熟，但我国电解水制氢-储氢-供氢的耦合发展正处于起步阶段，探索该耦合技术在电力系统中的发展对氢能与传统电力的协同利用具有重要意义。基于此，介绍了电解水制氢、储氢和供氢技术的基本原理、分类及其优缺点，总结了美国、日本和欧盟在电解水制氢-储氢-供氢产业的发展情况，分析我国从制氢到用氢的基本现状，讨论我国电解水制氢-储氢-供氢在电力系统中3种可能的应用模式。最后，基于现状提出推动我国电解水制氢-储氢-供氢在电力系统中发展的建议，为优化氢能的制-储-供-用全技术链发展提供参考。

Hydrogen energy has broad development prospects as a clean, carbon-free, flexible and efficient secondary energy and industrial raw material. Although the technologies of hydrogen production by water electrolysis, hydrogen storage and hydrogen supply have been relatively mature, the technology chain of hydrogen production-storage-supply is still in its infancy. It is of great importance to explore the technology chain in power system for the cooperative utilization of hydrogen energy and traditional electricity. This paper firstly introduced the basic principles, classifications, advantages and disadvantages of the technologies including hydrogen production by water electrolysis, hydrogen storage and hydrogen supply, and summarized the development of hydrogen production by water electrolysis, hydrogen storage and hydrogen supply technologies in the United States, Japan and the European Union. Then, the current status of above technologies in China was analyzed, and three possible application modes of hydrogen production by water electrolysis, hydrogen storage and hydrogen supply in power system in China were discussed. Finally, based on the current situation, the suggestions for promoting the development of hydrogen production by water electrolysis, hydrogen storage and hydrogen supply in power system in China were put forward, which provide a reference for optimizing the development of the whole technology chain of hydrogen energy production-storage-supply-use.
