Energy Dome, a leader in long-duration energy storage solutions, announces a historic advancement in its commercial-scale deployment in the U.S. market through a signed supply agreement for the Columbia Energy Storage Project with Alliant Energy.
According to Industry sources, having already secured a competitive cooperative agreement of up to $30 million from the U.S. Department of Energy’s Office of Clean Energy Demonstrations, this collaboration has recently reached another key milestone with Alliant Energy’s recent submission of its application for the Columbia Energy Storage Project with the Wisconsin Public Service Commission (PSC).
Claudio Spadacini, CEO of Energy Dome, expressed his excitement at achieving this milestone, stating: “This is great news for long-duration energy storage in North America. Our collaboration with Alliant Energy is forward-thinking – it’s not just about innovation, but about creating opportunities for imminent large-scale deployment in the U.S. energy sector. Our technology is poised to play a transformative role in the way energy is stored and managed.”
Raja Sundararajan, Executive Vice President of Alliant Energy, also expressed his satisfaction with this collaboration, noting: “We are very pleased to announce the signing of the supply contract with Energy Dome as a pioneer for the Columbia Energy Storage Project. It is a key turning point in this strategic partnership. After a thorough evaluation of the technologies available in the market, Energy Dome’s CO2 Battery stood out as a cost-effective, efficient, and scalable solution. We see this as the first of many CO2 Batteries that will be built in partnership between Energy Dome and Alliant to continue to provide reliable and affordable energy in the communities we serve.”
Industry sources further confirmed that the Columbia energy storage project will feature Energy Dome’s 20 MW/200 MWh CO2 Battery, which will power approximately 18,000 Wisconsin homes for 10 hours on a single charge. It focuses on setting a benchmark for other utilities and energy providers looking to boost their storage solutions and reduce carbon emissions. In particular, Energy Dome will support Alliant Energy throughout the project and ensure the effective incorporation of the CO2 Battery system into the energy infrastructure.
In parallel, the construction of Energy Dome’s first standard CO2 battery plant in Sardinia (Italy) is also progressing at full speed. The Sardinia plant is expected to be completed by the end of the first quarter of 2025, having received full notice to start work by the end of 2023, demonstrating Energy Dome’s ability to meet delivery deadlines in a short period.
Industry sources further added that it is worth noting that thanks to a modular and standardized approach, the Italian plant will be virtually identical to the one in the US, where the former will offer the ideal test bed from both a construction and operational perspective, ensuring a smooth process and the application of lessons learned to start construction of the American plant in Wisconsin.
