On March 23, the National Development and Reform Commission (NDRC) and the National Energy Administration of China Issued the Medium and Long Term Development Plan for Hydrogen Industry (2021-2035) to carry out demonstration applications in the field of energy storage. According to the plan, hydrogen has the advantages of a long cycle and large storage capacity, and hydrogen storage will be demonstrated in scenarios such as renewable energy uptake and peak regulation in the grid. China will explore the new mode for the application of "energy generation by wind and solar + energy storage by hydrogen", and gradually build an integrated energy storage system of pumped hydro storage, electrochemical storage, hydrogen storage, etc. And China will explore the synergistic optimization potential of hydrogen in different energy networks and promote the connectivity of electricity, heat, fuels, and other forms of energy resources.
