This pioneering project demonstrates the viability of integrating molten salt storage with coal-fired power generation at scale, providing critical technical support for building a clean and low-carbon modern energy system.
Over the recent years, energy storage in abandoned underground spaces has garnered considerable research attention, with various approaches such as PHS, CAES, gravity energy storage, and hydrogen storage being studied for application in abandoned coal mines [28, 30]. Among them, the ESD of PHS in coal mines is relatively low.
On April 11, China's first 600MW coal-fired molten salt energy storage project completed performance tests and officially commenced operation at Longshan Power Plant of CHN Energy Hebei Branch. As a key scientific initiative of CHN Energy, the 3.2-billion-RMB project spans approximately 7,900 square meters.
However, gravity energy storage is only applicable in abandoned coal mines with deep shafts, limiting its broader application. Additionally, large-scale deployment faces challenges such as safety hazards and difficulty in scaling. Hydrogen storage in coal mines is still in the theoretical research stage.
