Abstract:

With the gradual increase in the proportion of new energy, energy storage technology, as an auxiliary new energy grid, has attracted wide attention. Hydrogen energy storage and fuel cell technology have been listed as strategic energy technologies in China, and have been actively applied in the market and enterprise development. Hydrogen production from electrolytic water can stabilize the fluctuation caused by the connection of renewable energy to the grid and help the power grid to cut peak and frequency modulation. As a power generation device to improve energy conversion rate, fuel cell has the advantages of low noise and no pollution, it is one of the effective ways to absorb renewable energy. This paper made a comparative analysis of the development status and advantages of the existing energy storage technologies, the key technologies and research directions of hydrogen energy storage system were introduced emphatically, and the commercial development of hydrogen energy storage was prospected.

Key words: hydrogen energy, electrolysis hydrogen production, fuel cell, energy storage technology
