Understanding Gravity Energy Storage Technology. Gravity Energy Storage Technology, often reviated as GEST, operates on the principle of gravitational potential energy. It involves lifting heavy objects, such as massive weights or containers filled with materials, to a higher elevation when energy is abundant or inexpensive.
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.
