One of the other energy storage concepts, under the category of mechanical systems, is gravity, sometimes called a gravitational energy storage (GES) system. As the title makes it very clear, this concept pertains to taking advantage of the gravity of the Earth and storing electricity in the form of potential energy.
The hydraulic gravitational energy storage (HGES) concept could have various configurations which have been introduced and investigated before, for example, Heindl energy (HE) (Heindl Energy GmbH, n.d.); EscoVale known as ground-breaking (GB) energy storage (Escovale, n.d.); and Gravity Power (GP) gravity (Gravity Power, n.d.).
From the same procedure, the power density of the GES is formulated as below, in which the discharge time of the gravitational energy storage is represented by tdis. (14.8) P D = 2.78 × 10 − 7 ρ l sh g t dis
In this system, which is mainly appropriate for offshore wind or PV farms, the energy storage unit consists of an immersed hydraulic turbine/pump set connected to a submerged vessel capable of tolerating the high pressure of the seabed, and of course some other supplementary soft equipment for controlling and monitoring the system operation.
The stored energy density (kWh/m 3) is given by: (14.7) E D = E V C = 2.78 × 10 − 7 ρ g l sh in which VC refers to the volume of the cylinder. Also, it is assumed that the shaft diameter is equal to the cylinder diameter.
Selecting locations with higher elevation differences in between for installation improves performance and related costs. This technology has not matured yet and should be enriched by further research to prove that GES can be the future of energy storage and become competitive in comparison to other storage technologies.
