Application of Hydrogen Energy Storage Technology and its Impact on Short-circuit Current

Developing hydrogen energy storage technology is one of the important measures to accelerate the construction of New Power Systems and achieve the strategic goals of carbon peaking and carbon neutrality. To promote the application of hydrogen energy storage technology in power systems, firstly, the basic characteristics of hydrogen energy storage technology was introduced and its role in the power system was analyzed; Secondly, the principles of hydrogen energy storage technology in the power system were discussed from three aspects: electrolytic water hydrogen production technology, hydrogen storage technology, and hydrogen power generation technology; Then, the application of hydrogen energy storage technology on the power supply side, grid side, and user side was sorted out for the “source-grid-load” and other links in the New Power System; Finally, the problems and challenges of current hydrogen energy storage technology were discussed, and the development of hydrogen energy storage technology was prospected, aiming to provide reference for accelerating the application of hydrogen energy storage technology in power systems. The Impact of hydrogen energy storage on short-circuit current was discussed.
