Miniera d'Energia
From Prototype to Full-Scale Project
Energy Vault's hybrid energy storage system leverages existing infrastructure, advance modular gravity storage, and lithium-ion batteries to support the development of a carbon free technology hub at the former site of Italy’s largest coal mine.
Project Overview
Located at Carboluscis' Nuraxi Figus coal mine in Sardinia, Italy, Energy Vault, starting from a first industrial prototype, is developing an innovative hybrid gravity + battery energy storage system to help stabilize Sardinia's power grid. The Miniera d'Energia project will play a crucial role in aiding the Sardinian Government's ambition to transform the decommissioned mine into a carbon-neutral technology hub, reduce its environmental impact, and foster economic development in the area.
Energy Vault's hybrid solution incorporates the first commercial scale deployment of its modular pumped hydro system, EV0TM. The EV0TM system will repurpose the retired coal mine's unique underground features, including its 500-meter-deep mine shafts, to deliver a highly efficient gravity energy storage system. Acting in tandem with EV0TM, Energy Vault's B-VAULTTM battery energy storage solution will complement the gravity system to provide additional services on the Sardinian grid. Completion of the EV0TM prototype is slated for 2025 and the full system for 2027-2028* where Energy Vault will fully own and operate the site, demonstrating our commitment to being a long-term partner in the region's clean energy future.

"The Energy Vault team designed and deployed the optimal energy storage solution for our Stanton site. Only a few days after mechanical completion the system delivered full power to the grid validating the quality of the design and execution. Energy Vault did an excellent job of providing a solution that met both the challenging energy density requirements and the equipment delivery time frames to enable the project to go forward. We are a satisfied customer, and we appreciate Energy Vault’s expertise, creative thinking and collaborative partnership in bringing this project to fruition."
