Problems solved by technology

[0008] (1) The cost is high and the process is cumbersome

The light-collecting equipment of the solar thermal power plant is large in scale, and the volume of the thermochemical hydrogen production reaction system will also increase accordingly, and the cost will increase; in the process of building the system, considering factors such as power generation production and the extremely high temperature of the light-collecting equipment during the day, The construction process is very cumbersome

[0009] (2) The sunshine time and intensity of the sun are unstable, and are seriously affected by the weather. Usually, the stable heat supply required for the thermochemical hydrogen production reaction cannot be guaranteed, so the performance of the thermochemical hydrogen production reaction at a certain temperature point or temperature range cannot be evaluated.

[0010] (3) The concentrating temperature of solar thermal power plants is generally high, and only some high-temperature thermochemical hydrogen production reactions can be tested, which has certain limitations
