Energy Dome opens first CO2 Battery facility in Italy


Italy – Energy Dome has opened its first CO2 Battery facility in Sardinia, Italy.

As Energy Dome enters the commercial scaling phase, this milestone marks the final de-risking of the CO2 Battery technology, making it the first commercial long-duration energy storage technology on the market, providing a reliable alternative to fossil fuels for dispatchable baseload power around the world.

The CO2 Battery’s performance and ability to store energy for a long period of time have been confirmed during the initial phase of operations, all while maintaining highly competitive round-trip efficiency without degradation or site dependency. The Sardinia demonstration project has demonstrated this innovative process using off-the-shelf equipment from a globally established supply chain, demonstrating that the CO2 Battery can now be deployed globally quickly and without bottlenecks.

First commercial project

CO2 Batteries from Energy Dome can be deployed quickly anywhere in the world for less than half the cost of comparable-sized lithium-ion battery storage facilities, and they use readily available materials like carbon dioxide, steel, and water. Energy Dome is currently constructing its first full-scale 20MW-200MWh power plant. Commercial Operation Date, the company’s first commercial project, is expected to be operational by the end of 2023.

Multiple commercial agreements have already been signed, including one with A2A, an Italian utility, for the construction of a first 20MW-5h facility. Ansaldo Energia, a major provider of power generation plants and components, signed a non-exclusive license agreement with Energy Dome earlier this year to build long-duration energy storage projects in Italy, Germany, the Middle East, and Africa.

Investors in Energy Dome’s plan include 360 Capital, a European deeptech venture capital firm, Barclays, Novum Capital Partners, and Third Derivative.
