The hydrogen energy storage system has the advantages of cleanliness, high efficiency and sustainability in emergency power supply for plateau mining areas. However, its operational efficiency and safety are challenged by low air pressure, large temperature differences and harsh environments. Carrying out adaptive transformation in combination with the geographical and climatic characteristics of the plateau can improve the efficiency of electrolytic hydrogen production, the sealing performance of hydrogen storage, and the output stability of fuel cells under low oxygen conditions. Scientific capacity configuration not only affects the continuity and reliability of emergency power supply, but also relates to system economy and operation and maintenance costs. By analyzing energy demands under different working conditions and optimizing the efficiency of hydrogen production, storage and conversion, the precise matching between power supply capacity and actual load can be achieved, providing support for energy security in plateau mining areas and the construction of green mines.
