Energy Dome Closes $11M Convertible Round to Accelerate Commercial Deployment of CO2 Battery

MILAN–(BUSINESS WIRE)–Energy Dome, a leading provider of utility-scale long-life energy storage solutions, today announced the successful close of an $11 million bridge funding round .

The convertible funding was led by CDP Venture Capital Sgr’s Evolution fund, together with existing investor Barclays, as part of their Sustainable Impact Capital program which funds start-up companies accelerating the transition to a net zero future. CDP Venture Capital Sgr is an asset management company with more than 1.6 billion euros of assets under management, aiming to make venture capital a strategic pillar of economic growth and innovation in Italy and to create the conditions for global and sustainable growth of the ecosystem. The round was also joined by Swiss family office Novum Capital Partners, an existing shareholder of Energy Dome.

With the closing of this latest convertible round, Energy Dome has now raised a total of nearly $25 million since the company exited stealth mode in February 2020.

The last transition cycle was closed ahead of Energy Dome’s Series B cycle, which is scheduled for later in the year. The convertible funding follows the Series A funding round in November 2021, which was also $11 million and led by 360 Capital, Barclays, Novum Capital Partners and Third Derivative.

Energy Dome’s rapid technology development drives the speed and frequency of funding rounds. Series A enabled the company to complete its 2.5 MW/4 MWh commercial demonstration plant in Sardinia, Italy, the final step in de-risking technology. Energy Dome has started marketing the CO2 battery. This latest bridge financing will allow the company to accelerate its development ahead of the Series B round by placing purchase orders for the long-lead turbomachinery equipment associated with its large-scale First of a Kind energy ( 20 MW, 200 MWh, 10 hour duration) storage projects. A memorandum of understanding for this first utility-scale project has been signed with A2A, a major European utility, and the company is making strong progress on its commercial pipeline.

Energy Dome’s innovative technology is based on a new industrial process that integrates off-the-shelf components using established supply chains. The core engineering team has worked together for over a decade in previous ventures and brings deep expertise in process engineering and turbomachinery.

Energy Dome’s emission-free energy storage method uses CO2 as the working fluid in a closed loop to store renewable energy for four to 24 hours, then feed it back into the grid when needed, a missing piece part of the energy transition puzzle.

“This significant achievement will support our ambitious growth,” said Claudio Spadacini, Founder and CEO of Energy Dome. “I would like to welcome CDP Venture Capital Sgr to our team and thank them, along with Barclays and Novum Capital Partners, for their confidence in Energy Dome as we become a leading solution provider for the long-term energy storage market. ”

Their market launch is an exciting next step in Energy Dome’s journey, and we’re excited to continue our partnership as they evolve into the future. said James Ferrier, head of sustainable impact capital at Barclays.
