2. Gravity battery - Wikipedia

   en.wikipedia.org/wiki/Gravity_battery

   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.

3. Energy storage - Wikipedia

   en.wikipedia.org/wiki/Energy_storage

   Energy storage is the capture of energy ... The European Hyunder project indicated in 2013 that storage of wind and solar energy using underground hydrogen would ...

4. Grid energy storage - Wikipedia

   en.wikipedia.org/wiki/Grid_energy_storage

   Grid energy storage, also known as large-scale energy storage, are technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power , releasing it when needed.

8. Battery energy storage system - Wikipedia

   en.wikipedia.org/wiki/Battery_energy_storage_system

   A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy. Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used ...

9. Pumped-storage hydroelectricity - Wikipedia

   en.wikipedia.org/wiki/Pumped-storage...

   Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off ...
