Energy Vault will grid-tie a commercial-scale gravity-energy storage system in 2023. The world’s first non-PSH gravity-based storage plant located by a wind farm near Shanghai will provide 25 MW/100 MWh via solar-powered electric lifting. Large blocks are raised and lowered to dispatch electricity as needed with 75% round-trip efficiency.
