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. Converting between Joule (J) and Watt-hour (Wh) is done as in (2). (2) 1 kWh = 3.6 × 10 6 J.
Gravity Storage Technologies Gravity based energy storage technologies use the same principle as PHS systems. However, the important difference is that cement or bricks, or rocks are used as the mass moving up or down instead of water. The important advantage of this is that the size of the systems is much smaller due to the
