Energy Vault and coal mining company Carbosulcis are joining forces for the development of an energy storage project in Italy. With a planned capacity of 100MW, the system, specifically designed by Energy Vault for underground mines, will feature modular gravity storage and batteries.
The facility will be installed at Carbosulcis' Nuraxi Figus site, on the island of Sardinia. The coal mine will be retired by the end of 2026, with the Sardinian government willing to turn it into a technology hub.
According to the developers, the energy storage system will be deployed within 500 metres-deep mine shafts. It will leverage Energy Vault's EV0 gravity technology through a new water-based, modular pumped hydro application.
