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).
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.
The gravity power module (GPM) is a similar storage system to the piston based pumped hydroelectric system developed by Asmae Berrada et al., but it utilizes a much larger piston. This system provides power and energy in the range of 40 MW/160MWH to 1.6GW/6.4GWH [ 8 ].
A typical hydro system that rely on gravity to store energy is the dynamic modelling of gravity energy storage coupled with a PV energy plant work by Asmae Berrada et al. The aim of his model is to investigate gravity effect on energy storage.
Furthermore, Thomas Morstyn et al., developed the design of Gravity energy storage using suspended weights for abandoned mine shafts. Energy is stored in this system by delivering current from the electrical network to raise the suspended weights along the rail set up in the system.
Some of the aforementioned researches includes pumped hydro gravity storage system, Compressed air gravity storage system, suspended weight in abandoned mine shaft, dynamic modelling of gravity energy storage coupled with a PV energy plant and deep ocean gravity energy storage.
