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.).
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.

On the other hand, the energy storage density increases continuously with a linear trend. At optimum energy storage capacity points, its value is 2.061 kWh/m 3 for iron and 0.504 kWh/m 3 for sand shafts. Figure 14.15.
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.
As indicated, increasing the shaft diameter and the cylinder depth increases both energy storage capacity and shaft mass; however, the trend of increment of both the capacity and the mass sharply rises when the variables increase.
