Description

technical field [0001] The invention belongs to the technical field of superconducting energy storage and utilization for hydrogen production, and relates to a system and method for producing hydrogen by electrolyzing water with renewable energy to realize superconducting energy storage and utilization. Background technique [0002] Due to the strong volatility of renewable energy, there are energy waste problems such as abandoning wind, light, and water. Hydrogen production from renewable energy electrolyzed water is a key technology for renewable energy conversion. It can be used as a variable load for peak shaving and valley filling. The grid quality of renewable energy power generation can also effectively absorb abandoned wind, abandoned light, and abandoned water to improve the utilization rate of renewable energy, which can be used as an effective means of renewable energy consumption. At the same time, electrolytic water hydrogen production technology is green, envir...

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
