The National Development and Reform Commission’s “Guiding Opinions on Promoting Energy Storage Technology and Industrial Development” (hereinafter referred to as “Opinions”) pointed out that in recent years, China’s energy storage has shown a good momentum of diversified development: pumped storage has developed rapidly; compressed air Energy storage technology, flywheel energy storage, superconducting energy storage and supercapacitors, lead storage batteries, sodium-sulfur batteries, flow batteries and other energy storage technology development and application acceleration; heat storage, cold storage, hydrogen storage technology has also made certain progress.
　　"Opinions" proposed that during the "13th Five-Year Plan" period, a number of pilot demonstration projects of different technology types and different application scenarios will be built; a number of major key technologies and core equipment will be developed, and the main energy storage technologies will reach the international advanced level; preliminary establishment of energy storage The technical standards system forms a batch of key technical specifications and standards; explores a number of business models that can be promoted; and cultivates a number of competitive market players. The development of the energy storage industry has entered the early stage of commercialization, and the key role of energy storage for the transformation of the energy system has initially appeared.
　　The "Opinions" pointed out that during the "Fourteenth Five-Year Plan", energy storage projects were widely used, forming a relatively complete industrial system and becoming a new economic growth point in the energy field; fully mastering key energy storage technology and core equipment with international leading level, some Energy technology equipment leads the international development; forms a relatively complete technology and standard system and has the right to speak internationally; a variety of energy storage business models based on the electricity and energy markets are booming; a group of market players with international competitiveness are formed. The large-scale development of the energy storage industry has fully demonstrated the role of energy storage in promoting energy reform and the development of the energy internet.
　　The "Opinions" propose to promote the research and development demonstration of energy storage technology equipment; promote the application demonstration of energy storage to improve the utilization level of renewable energy; promote the application demonstration of energy storage to enhance the flexibility and stability of the power system; promote the application demonstration of energy storage to enhance the intelligent level of energy use; Promote the diversified application of energy storage to support energy Internet application demonstration and other five key tasks in the future.
