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.
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).
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 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.
They can be summarized into two aspects: principle and equipment. As for the principle, although each technological route lifts heavy objects in different ways (e.g., using ropes, carriers, or water currents), they all do so by lifting heavy objects to store electrical energy. This is the reason why they are all called solid gravity energy storage.
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.
