Abstract

The invention provides a solar optothermal coupled high-temperature water electrolysis hydrogen production system. The system comprises a heat energy supply module, a hydrogen production and separation module and a storage module which are sequentially connected; the heat energy supply module comprises a condensation device, a heat collection device, a heat storage high-temperature heat pipe heat exchanger and a heat exchanger unit which are sequentially connected, and hydrogen and hydrogen are separated through electrolysis after a water and hydrogen mixture in the hydrogen production and separation module is heated into a steam and hydrogen mixture above 800 DEG C. Compared with the prior art, the hydrogen production system has the advantages that fossil energy does not need to be consumed, the productive process is more green and environmentally friendly, and the power consumption is greatly reduced; a stable heat source is provided through the system, the problem that a photo-thermal system is not stable due to changes in the weather is solved, the availability of the system is improved, and meanwhile the electrolytic efficiency of the system is improved.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of solar energy and hydrogen energy, in particular to a high-temperature electrolytic water hydrogen production system coupled with solar light and heat. Background technique [0002] Hydrogen energy is recognized as a clean energy source and is emerging as a low-carbon and zero-carbon energy source. It is light in weight, high in calorific value, good in combustion performance, non-toxic and recyclable, and is a high-quality secondary energy source. However, an important factor restricting the large-scale commercial application of hydrogen energy is that a cheap hydrogen production technology has not yet been found. While solar energy is the most common primary energy source, the operating cost of solar thermal heating technology is very low, completely green and zero-emission, combining solar energy with hydrogen energy, and developing a cheaper hydrogen production technology is the foc...
