Gravity energy storage systems, using weights lifted and lowered by electric winches to store energy, have great potential to deliver valuable energy storage services to enable this transformation.
The Gravitricity system Gravity energy storage systems depend on the principle of lifting one or more solid masses a vertical distance in order to increase their gravitational potential energy. The system must then be reversible to allow the lowering of the weight (s) to result in useful release of the stored energy, less any efficiency losses.
