What is a mechanical energy storage system

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. The energy storage system "discharges" power when water, pulled by gravity, is released back to the lower-elevation reservoir and passes through a turbine along the way. The movement of water through the turbine generates power that is fed into electric grid systems. ... A flywheel is a mechanical energy storage device in which a rotating ...
