Author to whom correspondence should be addressed. Gravity energy storage, a technology based on gravitational potential energy conversion, offers advantages including long lifespan, environmental friendliness, and low maintenance costs, demonstrating broad application prospects in renewable energy integration and grid peak regulation.
The fundamental principle of gravity energy storage technology is to achieve the conversion between gravitational potential energy and electrical energy through the lifting and lowering of heavy objects. During the lifting phase, excess electrical energy is converted into gravitational potential energy for storage.
Oriented preferred solid gravity storage forms based on practical demands. With the continuous increase in the proportion of renewable energy on the power grid, the stability of the grid is affected, and energy storage technology emerges as a major solution to address such challenges.
Compared with other energy storage methods, gravity energy storage has the following advantages: First, it has a longer lifespan, less wear and tear on the mechanical system, and compared with LIBES, it has a higher cycle life and lower decay rate.
