As part of the global transition from research to commercial deployment of cleantech technologies, Energy Dome, a visionary long-duration energy storage (LDES) technology company, and ENGIE a global reference in low-carbon energy and services, have signed an offtake agreement for the first full-scale CO2 Battery developed by Energy Dome in Ottana, Sardinia, Italy.
The agreement underscores the importance of long-duration energy storage in enhancing grid resilience and reliability, demonstrating the value of the CO2 Battery technology for industry leaders and markets alike. ENGIE’s involvement in the project aligns with its strategy to strengthen its position in energy storage, leveraging flexible and dispatchable solutions such as the CO2 Battery to meet growing renewable energy needs. In Italy ENGIE has been pioneering the dispatching and the optimization of BESS (battery energy storage systems) since 2023; with an existing portfolio of 43 MW/48 MWh, the agreement with Energy Dome will consolidate ENGIE’s know-how in storage optimization.
Edouard Neviaski, CEO of ENGIE’s business entity ‘Global Energy Management & Sales’, said: “ENGIE is thrilled to partner with Energy Dome on this groundbreaking energy storage project. This collaboration highlights our unwavering commitment to developing sustainable and flexible solutions that drive the energy transition. By strengthening our expertise in energy storage, we are advancing our mission to provide reliable, low-carbon energy solutions that meet the increasing demand for renewables and support our customers on their decarbonization journey.”
Mario Fernandez, Head of Catalyst, Breakthrough Energy, said: “Scaling first-of-a-kind projects is immensely complex and requires not just technological innovation but new commercial and market approaches. This partnership is a tangible example of a replicable commercial innovation and confirms the Ottana CO2 Battery is not just a demonstration but a viable facility, which will unlock Nth-of-a-kind opportunities that can lead to true global scale.”
Claudio Spadacini, CEO of Energy Dome, commented on the milestone: “Our agreement with ENGIE confirms our deployment readiness, validates our business model, and underlines the market-leading value proposition of our technology. The era of deployment has arrived, and this collaboration will undoubtedly accelerate our mission to decarbonise the world by providing sustainable, utility-scale energy storage.”
The partnership represents Energy Dome’s first offtake deal under its “Energy Storage as a Service” model. This commercial arrangement with ENGIE, along with a recent equipment supply contract for a project with Alliant Energy in the US, demonstrates Energy Dome’s market readiness to scale its energy storage solutions at a commercial level, which was made possible also through public support mechanisms dedicated to accelerating emerging clean technologies.
