Solid energy storage technologies based on gravity potential energy

Abstract

In contemporary energy systems, energy storage plays a pivotal role, offering benefits such as grid stability improvement, increased integration of renewable energy sources, enhanced energy system efficiency, preservation of fossil fuel resources, and reduced environmental impact during energy generation. Globally meeting these requirements without adverse environmental effects is attainable through the utilization of gravity energy. Gravity energy presents an attractive option for energy storage due to its inexhaustible nature, lack of reliance on harmful resources, and global accessibility. Employing a gravity-based power generation mechanism involves storing off-peak electricity as potential energy, subsequently releasing it when power demand arises during discharge mode.
