Abstract

The invention discloses a solar comprehensive hydrogen production system, comprising: a photo-thermal system capable of absorbing heat of solar energy; a heat storage system which is used for storing heat of the photo-thermal system; and a thermochemical hydrogen production system, wherein the heat storage system can provide heat for the thermochemical hydrogen production system, so that the thermochemical hydrogen production system reacts to prepare hydrogen. According to the invention, unstable light energy is converted into stable heat energy, and hydrogen is prepared through the stable heat energy and the thermochemical hydrogen production system, so that 24-hour continuous hydrogen production can be realized, and continuous production of hydrogen is ensured. According to the invention, a photo-thermal / photovoltaic coupling system is established, and comprehensive hydrogen production in two ways of electric and thermal driving is realized, so that the utilization rate of solar energy and the yield of hydrogen energy are improved. The invention further discloses an energy supply system, in the energy supply system, the photovoltaic system and the hydrogen storage system are combined, and the effects of electric power peak regulation and absorption can be achieved.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, and more specifically relates to a solar energy comprehensive hydrogen production system and an energy supply system. Background technique [0002] At present, the commonly used hydrogen production technology is hydrogen production by electrolysis of water. The production of hydrogen by electrolysis of water requires a large amount of electric energy, and the electric energy is directly supplied by the power grid. Therefore, the cost of hydrogen production by electrolysis of water is relatively high. Solar energy is a clean and friendly renewable energy, widely distributed, and inexhaustible. In recent years, researchers have considered using photovoltaic power generation to electrolyze water to produce hydrogen, which can improve economic benefits. However, photovoltaic power generation is directly affected by seasons and weather, and its volatility is large, which in turn affects t...
