Abstract: Based on the technologies of wind-solar hybrid power generation, hydrogen generation from electrolysis of water, hydrogen storage, and hydrogen fuel cell, and by taking hydrogen as the core energy carrier, the integrated system of hybrid wind-solar hybrid power generation coupled with hydrogen-based energy storage is expected to be the key routine to the large-scale application of renewable energy-hydrogen energy-electricity energy. In this paper, the current development status about the key technologies were reviewed first including wind-solar hybrid power generation, hydrogen generation from electrolysis of water, hydrogen storage, hydrogen fuel cell and so on. Then the hot topics such as off-grid system, grid system, and capacity configuration optimization for the as-discussed integrated system were analyzed in details. The following progress analysis provided valuable reference for further technical research and engineering application with regard to the integrated system of hybrid wind-solar hybrid power generation coupled with hydrogen-based energy storage.
