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.

Its basic technical route is to use new energy such as wind and solar power or grid valley and flat power to raise the gravity block to a certain height, so as to convert the electric energy into potential energy for storage." According to Energy Vault, the EVx system is expected to have round trip efficiency (RTE) above 80%.
