OverviewTechnical backgroundDevelopmentMechanisms and partsTypes of gravity batteriesEconomics and efficiencyEnvironmental impactsGravity (chemical) battery

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 and solar provide more energy than is immediately required, the excess energy is used to move a mass upward agains
