How does a mechanical storage system work?
Mechanical storage systems work on the basis of storing available and off-peak excessive electricity in the form of mechanical energy. Once the demand for electricity power overcome the available energy supply, the stored energy would be release to meet with the energy demand.
What is a mechanical stored energy system?
Another theoretical mechanical stored energy concept is called the gravity power storage system. Unlike the hydraulic rock storage system described in Abschn. 9.3.2.1, the dimensions of the gravity power system are small. The storage principle is also slightly different, since it uses the same principle as the power tower system (Abschn. 9.3.2.3 ).
