At an old coal mine in the Czech Republic, engineers are building a new type of energy-storage device. It’s effectively a battery that works on gravity. The system will lift and lower heavy blocks in the mine shaft as a way to store energy and make electricity. Gravitricity “It’s a gravity energy-storage system,” explains Gavin Edwards.
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.
These forms include Tower Gravity Energy Storage (TGES), Mountain Gravity Energy Storage (MGES), Advanced Rail Energy Storage (ARES), and Shaft Gravity Energy Storage (SGES). The advantages and disadvantages of each technology are analyzed to provide insights for the development of gravity energy storage.
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).
In 2017, Tan et al. proposed an efficient gravity energy storage (GES) device shown in Fig. 2(a), using movable pulley blocks to lift heavy objects, which effectively reduces energy loss. The comprehensive energy conversion efficiency of the proposed device can reach more than 96 %.
Gravity-based systems exemplify the idea of potential and kinetic energy. Potential energy is defined by something’s position, such as its height above the ground. Kinetic energy is defined as the energy embodied by something in motion. Gravity systems gain more potential energy as something heavy — water, stone or gravel — is hoisted up.
