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.

Energy storage is the capture of energy produced at one time for use at a later time[1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential

Energy storage capacity. To analyse the energy storage capacity, the potential energy of the piston can be stated as (1) E = mgh, where m is the mass in kg, g is the gravitational constant (9.81 m/s 2) and h is the height.

The change in gravitational potential energy (ΔPEg) between points A and B is independent of the path. The equation ΔPE g = mgh applies for any path that has a change in height of h, not just when the mass is lifted straight up. (See Figure 2.) It is much easier to calculate mgh (a simple multiplication) than it is to calculate the work done
