3.1. 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.
The project is designed to have an energy storage capacity of 100 megawatt-hours, which can power 3,400 homes for a day, and the system is expected to be completed in June.
