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 requi...

Abstract

The invention discloses a solar power generating system and a solar hydrogen energy storage device. The solar power generating system comprises solar power generating equipment and a hydrogen energy storage device, wherein the hydrogen energy storage device comprises an electrolytic bath with a hydrogen collection room; an electrode in the electrolytic bath is connected with direct current output by the solar power generating equipment; electrolyte in the electrolytic bath can generate hydrogen under the action of the direct current; and the generated hydrogen is stored in a hydrogen storer which is communicated with the hydrogen collection room. In the technical scheme of the invention, solar energy can be stored in the mode of the hydrogen, and the stored hydrogen can be used as a fuel for generating electricity under the condition of weaker light or no light, thereby effectively improving the practicability of the solar power generating system and being convenient for the popularization and the application of the solar power generating system.

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 ...
