Problems solved by technology
Direct immersion cooling The HTSES magnet is directly immersed in the Dewar filled with liquid hydrogen. The advantage is that the direct immersion cooling power is large, and the HTSES magnet is running The external thermal disturbance is small, and the disadvantage is that with the operation of the energy storage high-temperature superconducting energy storage magnet system, it is necessary to continuously add liquid hydrogen to the Dewar
The refrigeration of the refrigerator does not require frequent addition of liquid hydrogen to the Dewar, but the cooling effect of the refrigerator is not as good as that of direct immersion, and the operation and maintenance of the refrigerator in the later stage is very cumbersome

Description
technical field [0001] The invention belongs to the technical field of hydrogen production, superconducting energy storage and utilization, and relates to a system and method for realizing superconducting energy storage and utilization by electrolyzing water with renewable energy to produce hydrogen. Background technique [0002] Due to the strong volatility of renewable energy, there are energy waste problems such as abandoning wind, abandoning light, and abandoning water. Renewable energy electrolysis of water to produce hydrogen is a key technology for renewable energy conversion. It can be used as a variable load to cut peaks and fill valleys to improve The quality of renewable energy power generation on the grid can effectively absorb abandoned wind, abandoned light, and abandoned water to improve the utilization rate of renewable energy, and can be used as an effective means of renewable energy consumption. At the same time, the electrolytic water hydrogen production t...
