Problems solved by technology

The main problems of this method are: ① separation of hydrogen and oxygen at high temperature; ② material problem of high temperature solar reactor
[0008] The tower system is a solar hydrogen production system that uses a solar mirror as a heliostat and focuses multiple solar reflectors on a hydrogen production device. The use time is only 4-6 hours. For example, the solar mirror on the east side of the tower is basically unusable in the morning, and can only be used after noon or afternoon, so the efficiency of solar energy collection is low. This technical solution can achieve high temperature collection, but usually Its large size is not suitable for small or home systems

Abstract

The invention relates to the focusing utilization of solar energy, in particular to a solar energy hydrogen production system which realizes solar energy acquisition by adopting point focused solar mirrors and is applied to a fixed point array. The solar energy hydrogen production system comprises at least one or at least one group of point focused solar mirrors, at least one hydrogen production device and tracking control devices, wherein the solar mirrors are arranged on a solar mirror support, the hydrogen production devices are arranged in solar mirror focused punctate areas and are above or below the solar mirrors, the solar mirrors change in focal length in the process of tracking solar energy, and the focal lengths of the solar mirrors are maintained to be always positioned in punctate areas of the hydrogen production devices; and the tracking control devices are used for controlling the solar mirrors to focus sunlight to at least one hydrogen production device when the sunlight changes, and the hydrogen production devices do not move together with the solar mirrors in the process that the solar mirrors track the solar energy but maintain relative rest with the ground so as to realize the tracked focusing utilization of the solar energy.
