The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.
Various energy storage technologies and risks in coal mine are analyzed. A significant percentage of renewable energy is connected to the grid but of the time-space imbalance of renewable energy, that raises the need for energy storage technologies.
While making full use of coal to develop underground space resources, it realizes power conversion and storage, stabilizes the power system''s cycle and voltage, promotes the circulation of mine water, and guarantees flood storage and water transfer.
(3) Provide financial incentives, such as subsidies, tax breaks and investment incentives, to attract investors to participate in coal mine energy storage projects. (4) Support technological innovation and R & D to promote the application and commercialization of new technologies in the field of coal mine energy storage.
