Solid gravity energy storage technology has the potential advantages of wide geographical adaptability, high cycle efficiency, good economy, and high reliability, and it is prospected to have a broad application in vast new energy-rich areas.
Classification of energy storage technologies. Gravity energy storage technology (GES) depends on the vertical movement of a heavy object in a gravitational field to store or release electricity.
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.
The motor-generation unit is the energy conversion hub of solid gravity energy storage, which directly determines the cycle efficiency of solid gravity energy storage technology. The current efficiency of motor-generation units is about 90 %, so SGES's cycle efficiency is around 80 %.
Solid gravity energy storage technology has as many as eight technical routes. Although the technical routes are different, some essential features are the same. They can be summarized into two aspects: principle and equipment.
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).
This "repairability" means gravity batteries can last as long as 50 years, says Asmae Berrada, an energy storage specialist at the International University of Rabat in Morocco.
