Energy Dome has opened a manufacturing plant in Piacenza, Italy, dedicated to producing key components such as the large domes used in its carbon dioxide-based energy storage systems. This expansion supports the company's international long-duration energy storage (LDES) projects.
The first dome manufactured entirely in-house has been shipped to India for the 20 MW/160 MWh Kudgi project with NTPC. Production is also underway for projects in Wisconsin, United States (20 MW/200 MWh), and Rhode, Ireland (23 MW/200 MWh).
Investment and Capacity Expansion Plans
Energy Dome invested approximately €2.2 million in the Piacenza site over the past year to upgrade facilities, acquire machinery, and improve infrastructure. The company plans to increase total investment to about €6.5 million over the next two years.
The goal is to triple production capacity and expand the local workforce from 30 employees to between 80 and 90 by 2028.
Market Presence and Strategic Supply Chains
Energy Dome leverages European manufacturing supply chains, including steel and turbomachinery, rather than relying on non-European sources. The company has a presence across four continents with over 2 GWh of projects operational or under contract, more than 3 GWh authorized, and a development pipeline exceeding 30 GWh.
Its customers and partners include Google, Engie, Alliant Energy, NTPC, SEC, and SRP. Additionally, Italy’s National Integrated Energy and Climate Plan, grid operator Terna’s need for 50 GWh of storage by 2030, and the MACSE storage procurement mechanism support growing demand for energy storage.
