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
