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.
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).
The proposed energy management system performs well in natural power systems. As a new type of large-scale energy storage technology, gravity energy storage technology will provide vital support for building renewable power systems with robust performance.
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-based gravity energy storage (GES) technology is a new type of large-scale, mechanical energy storage technology similar to the widely used pumped hydro storage [ 8, 9 ]. Gravity energy storage has high investment costs for installed capacity while low for energy storage.
The use of modular weights for gravity energy storage power plants has great advantages over standalone weights, such as flexibility in output power, ease of mass production of related equipment and better flexibility in the selection of weights, etc., and M-GES is receiving increasingly widespread attention.
