In a broad sense, gravity energy storage (GES) refers to mechanical technologies that utilize the height drop of energy storage media, such as water or solid, to realize the charging and discharging process of energy storage. Pumped energy storage is also a form of GES.
These forms include Tower Gravity Energy Storage (TGES), Mountain Gravity Energy Storage (MGES), Advanced Rail Energy Storage (ARES), and Shaft Gravity Energy Storage (SGES). The advantages and disadvantages of each technology are analyzed to provide insights for the development of gravity energy storage.
Solid gravity energy storage technology (SGES) is a promising mechanical energy storage technology suitable for large-scale applications. However, no systematic summary of this technology research and application progress has been seen.
In conclusion, solid gravity energy storage systems are emerging alternatives to pumped hydro energy storage systems. They have the means to address issues related to geographical adaptability and scalability. In the recent years, there has a surging interest in studying and building these systems.
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.
