Metal or non-metal production system with hydrogen as reducing agent

The utility model provides a metal or nonmetal production system with hydrogen as a reducing agent. The metal or nonmetal production system comprises a renewable energy power generation unit, a water electrolysis hydrogen production unit, a hydrogen storage unit, a hydrogen reduction unit, a hydrogen circulation unit, a water circulation unit and a hydrogen energy conversion unit. According to the production system, only renewable energy serves as driving energy, water and oxide ore serve as raw materials, elemental metal or nonmetal is obtained from the oxide ore under the reduction effect of the intermediate material hydrogen, and the production system is an innovative metal/nonmetal green extraction technology; hydrogen serves as an energy storage carrier, the problems of volatility, intermittency and non-storability of renewable energy sources can be solved, continuous and stable operation of a production system can be guaranteed, the technology is a technology for highly coupling and using renewable ener
