Author to whom correspondence should be addressed. Gravity energy storage, a technology based on gravitational potential energy conversion, offers advantages including long lifespan, environmental friendliness, and low maintenance costs, demonstrating broad application prospects in renewable energy integration and grid peak regulation.
The system’s overall round-trip efficiency ranges between 70 and 75%. The entire process is chemical-free and environmentally friendly. Suitable for mountainous areas and abandoned mines, several pilot projects of rail-mounted gravity energy storage systems have already been implemented.
The Gravitricity project has validated the feasibility of constructing gravity energy storage systems using abandoned mines. S-SGES offers advantages such as high response speed and long service life, making it an ideal solution for grid frequency regulation and integration with renewable energy storage.
Its working principle is similar to that of tower-based gravity energy storage, except that this system employs natural underground shafts or abandoned mines to lift heavy weights. This approach fully leverages existing underground spaces, reduces construction costs, and minimizes surface land occupation.
China, abundant in mountain resources, presents good development prospects for MGES, particularly in small islands and coastal areas. In mountainous regions with suitable track laying and a certain slope, rail-type gravity energy storage exhibits significant development potential and can essentially replace pumped storage.
