Hydrogen Production by Renewable Energy and Future Trend in China

Hydrogen energy is a clean, flexible, zero-carbon secondary energy source which can be stored and transported long distance. With the continuous increase of installed capacity proportion of renewable energy in the future, it can be used as a carrier to stabilize the fluctuation of renewable energy and optimize the power system operation, helping the country's clean and low-carbon energy transformation. The continuous large-scale development of renewable energy will continue to reduce the cost of green hydrogen production, and green hydrogen may become the future development trend. This paper introduces current status of China's hydrogen energy, and the main renewable energy hydrogen production technologies by wind power, PV power, biomass, etc, and analyzed the obstacles of power system that brought by the green hydrogen production, finally proposed the future development mode of the hydrogen and the power system.
