The 25 MW/100 MWh EVx™ Gravity Energy Storage System (GESS) is a 4-hour duration project. It is being built outside of Shanghai in Rudong, Jiangsu Province, China, and is under construction directly adjacent to a wind farm and national grid.
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.
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.
Gravity based pumped-storage electricity is the largest form of grid energy storage in the world.
This paper conducts a comparative analysis of four primary gravity energy storage forms in terms of technical principles, application practices, and potentials. These forms include Tower Gravity Energy Storage (TGES), Mountain Gravity Energy Storage (MGES), Advanced Rail Energy Storage (ARES), and Shaft Gravity Energy Storage (SGES).

Pumped-storage hydroelectricity (PSH) is the most widely used and highest-capacity form of grid-energy storage. In PSH, water is pumped from a lower reservoir to a higher reservoir, which can then be released through turbines to produce energy. An alternative PSH proposal uses a proprietary high-density liquid, 2+1⁄2 times denser than water, which requires a smaller head (elevation…
