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.
4.1.2. Multiweight The energy storage capacity of a gravity energy storage system can be scaled up and optimized by using multiple weights.
In simple terms a gravity energy storage device uses an electric lifting system to raise one or more weights a vertical distance thereby transferring electrical energy to be stored as gravitational potential energy.
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.

Pumpkraftverk. Med ett pumpkraftverk kan elektrisk energi lagras genom att pumpa vatten från en lägre placerad reservoar till en högre. Energin är då lagrad som lägesenergi och utvinns genom att vattnet släpps tillbaka via en vattenturbin med en generator som producerar elektrisk energi.

Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the weight.
