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.
Fig. 2: A diagram of the essential components of a tower solid gravity energy storage system (Image source: S. Blinkman). The T-SGES system, as depicted in Fig. 2, uses electromechanical motor-generation units to lift and stack blocks into a tower. As more energy is stored, the control center stack blocks onto higher blocks.
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.).
A gravity battery is a type of energy storage device that stores gravitational energy —the potential energy E given to an object with a mass m when it is raised against the force of gravity of Earth (g, 9.8 m/s²) into a height difference h.
