What is the motor of gravity energy storage

A gravity battery is a type of energy storage device that stores gravitational energy—the potential energy E given to an object with a mass m when it is raised against the force of gravity of Earth (g, 9.8 m/s²) into a height difference h. In a common application, when renewable energy sources such as wind.

gravity energy storage

Energy is used to raise a mass through a height thus storing energy as gravitational potential energy. The amount of energy stored is mass times gravitational acceleration times height raised. The most common large scale use of gravity energy storage in current use is pumped hydro storage, shown in the diagram on the left.
