A gravity battery is a type of energy storage device that stores gravitational energy—the potential energy E given to an object with a mass m when it is raised against the force of gravity of Earth (g, 9.8 m/s²) into a height difference h. In a common application, when renewable energy sources such as wind.

An old and simple application is thedriven 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 .

The earliest form of a device that used gravity to power mechanical movement was the , invented in 1656 by . The clock was powered by the force of gravity using anmechanism, that made a pendulum move back.

Large scale (PSH) is the most widely used and highest-capacity form of grid-energy storage. In PSH, water is pumped from a lower reservoir to a higher reservoir, which can then be released through turbines.

Gravity batteries are designed to be paired withsolutions whose sources (sunlight, wind, etc) are frequently variable and do not.

Gravity batteries can have different designs and structures, but all gravity batteries use the same properties of physics to generate energy. Gravitational potential energy is the work required to move an object in the opposite direction of Earth's gravity.

Cost of gravity batteries varies by design.Pumped storagecosts $165/MWh to operate, with a(LCOS).

From 1870 to 1930,the term "gravity battery" was used to describe a collection of popular battery types where gravity was used to keep the chemical constituents separate based on their respective densities.
