DEFINITION: The storage of energy by applying force to an appropriate medium to deliver acceleration, compression, or displacement (against gravity); the process can be reversed to recover the stored kinetic or potential energy. Currently, the most widely deployed large-scale mechanical energy storage technology is pumped hydro-storage (PHS).
