Description

technical field [0001] The invention relates to solar power generation technology, in particular to a solar power generation system and a solar hydrogen energy storage device. Background technique [0002] Because the sunlight is blocked by clouds and there is no sunlight at night, the solar power generation system will not be able to generate new electricity during the above-mentioned period of time, and this period of time is often the peak of electricity consumption such as lighting. Under sufficient conditions, it is a technical problem that needs to be solved to store the abundant power generated by the solar power generation system to meet the electricity demand under the condition of no sunlight. [0003] At present, solar energy storage mainly includes three methods: high-temperature steam energy storage, high-temperature molten salt heat storage and battery power storage. Among them, high-temperature steam energy storage mainly focuses multiple solar concentrators ...

AI Technical Summary

Problems solved by technology

[0004] However, among the above-mentioned solar energy storage methods, high-temperature steam energy storage is only suitable for centralized solar thermal power generation systems using steam turbine technology, and is not suitable for other non-steam turbine power generation systems. Difficult, heat is easily lost, and the energy storage effect is poor; the high-temperature molten salt heat storage method requires a large number of salt material storage tanks, high-temperature and corrosion-resistant pumps, pipelines and a large number of insulation measures, the cost is high and the technology is complicated, and the conversion of heat energy is also difficult. Inconvenient; the battery storage method is simple to implement, but the cost is too high, and the battery is polluted, which is easy to cause environmental pollution
