Energy Vault's 148-meter gravity storage tower in China stores wind power using concrete blocks
By
Ellsworth Toohey
Summary
Energy Vault's 148-meter tower in Rudong, Jiangsu, China stores surplus wind power by hoisting 35-ton concrete blocks made from recycled materials. When electricity is needed, the blocks descend to spin generators. The tower stores 100 MWh and delivers 25 MW, demonstrating a gravity-based energy storage solution for renewable power grids.
