Gravity energy storage is a form of mechanical energy storage that uses the earth''s gravity to store energy. The energy is stored in the form of potential energy, which is the energy that an object possesses due to its position relative to other objects. The higher an object is placed, the greater its potential energy.
According to the form of energy storage, energy storage technologies can be divided into mechanical energy storage, electrochemical energy storage, electrical energy storage, chemical energy storage, and thermal energy storage, as shown in Fig. 1 om the energy storage division perspective, gravity energy storage is most similar
