Energy Dome opens CO2 battery manufacturing plant in Italy

Energy Dome, an Italian long-duration energy storage company, has opened a manufacturing plant in Piacenza, Italy, to produce components for its CO2 Battery technology. The facility will focus on manufacturing large domes integral to the company’s carbon dioxide-based energy storage systems. Energy Dome plans to supply these components to projects worldwide, including a 20 MW/160 MWh project in India with NTPC and a 20 MW/200 MWh project in Wisconsin, United States, with Alliant Energy.

The company has already shipped its first in-house manufactured dome to India for the Kudgi project, marking a significant milestone in its production expansion. Additional domes are being produced for projects in the United States and Ireland, with the company leveraging European supply chains for steel and turbomachinery. Energy Dome’s technology is designed to support long-duration energy storage, addressing grid stability and renewable energy integration needs.

Energy Dome invested approximately €2 million in upgrading the Piacenza site over the past year, including building modifications, machinery acquisition, and electrical and network infrastructure improvements. The company plans to increase total investment to approximately €6.5 million over the next two years, aiming to triple production capacity and expand its local workforce from 30 to between 80 and 90 employees by 2028.

The company reports a global presence with over 2 GWh of projects operational or under contract, more than 3 GWh of authorized projects, and a development pipeline exceeding 30 GWh. Energy Dome’s customers and partners include major entities such as Google, Engie, Alliant Energy, NTPC, SEC, and SRP. The company highlights supportive policies in Italy, including the National Integrated Energy and Climate Plan and grid operator Terna’s storage procurement targets, as key drivers for demand.
