Energy Dome opened a manufacturing plant in Piacenza, Italy to build components for its CO2 battery systems. The company has spent about 2 million euros on the site and plans to invest 6.5 million euros over two years. It expects to triple production capacity and grow the local team from roughly 30 to 80-90 workers by 2028. The first fully in-house dome has shipped to India for the 20MW/160MWh Kudgi project with NTPC. Production is also underway for the 20MW/200MWh Columbia Energy Storage Project in Wisconsin with Alliant Energy, and a 23MW/200MWh project in Ireland with Google. The CO2 battery works as a closed thermodynamic cycle. Electricity drives a compressor that pressurizes CO2 and stores heat. The CO2 is liquefied and held in tanks, then heated and expanded through a turbine to discharge power. Energy Dome says the system relies on steel, water, and CO2 rather than lithium, and that its supply chain draws on European steel and turbomachinery. The company reports over 2GWh of projects in operation or under contract, over 3GWh authorized, and a development pipeline above 30GWh.
