Abstract: With the grid-connected ratio of renewable energy growing up, the development of energy storage technology has received widespread attention. Gravity energy storage, as one of the new physical energy storage technologies, has outstanding strengths in environmental protection and economy.
The Gravitricity system Gravity energy storage systems depend on the principle of lifting one or more solid masses a vertical distance in order to increase their gravitational potential energy. The system must then be reversible to allow the lowering of the weight (s) to result in useful release of the stored energy, less any efficiency losses.
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.
Solid gravity energy storage technology (SGES) is a promising mechanical energy storage technology suitable for large-scale applications. However, no systematic summary of this technology research and application progress has been seen.
To investigate the economic performance of differently sized gravity energy storage systems, a wind farm with a number of gravity energy storage units has been used. The principle of economies of scale has been applied resulting in a cost reduction for large scale systems.
