Italian startup Strength Dome has now started to commercialize the world’s initial CO2 Battery, which was introduced before this thirty day period in Sardinia, Italy. The battery employs carbon dioxide to keep renewable strength on the grid, and Energy Dome claims the technology can be promptly deployed anywhere in the globe.

June 28 update: Electricity Dome currently declared that it has secured $11 million in bridge funding, which will help it to get products for a 20-megawatt/200-megawatt-hour/10-hour length facility for Italian utility A2A, with which it has a memorandum of knowledge.

The Evolution Fund of asset management business CDP Enterprise Funds Sgr, alongside one another with existing trader Barclays, led the convertible funding. Swiss loved ones workplace Novum Cash Partners, an existing shareholder in Electricity Dome, also joined the spherical. 

With the closing of this latest convertible round, Energy Dome has now elevated a overall of virtually $25 million given that the company emerged from stealth mode in February 2020. Its sequence B round is planned for later in 2022.


World’s very first CO2 Battery

Electrical power Dome sited the CO2 Battery in Sardinia to favor velocity to marketplace and simplicity of execution, as it’s in an industrial location with an present electrical link. Further more, Sardinia at this time works by using coal, but the fossil gas will be phased out by 2025. The battery can be paired with the two wind and solar.

Electrical power Dome started its functions in February 2020 and has progressed from a strategy to full screening at multimegawatt scale in just more than two many years.

 Energy Dome Founder and CEO Claudio Spadacini mentioned:

The CO2 Battery is now commercially accessible to make value-effective renewable energy dispatchable on a international scale.

Power Dome asserted that its CO2 Battery facility in Sardinia employs off-the-shelf products available from a globally recognized supply chain, and explained that quick worldwide deployment of the CO2 Battery is now probable with out bottlenecks. 

The company has secured a number of industrial agreements, which includes one with Italian utility A2A for the development of the 1st 20 MW-5h facility. Before this year, Electricity Dome also signed a nonexclusive license arrangement with Ansaldo Energia, a electric power era plant and ingredient provider, to build extended-duration strength storage assignments in Italy, Germany, the Center East, and Africa.

Strength Dome’s approach is backed by traders that involve European deep tech undertaking cash business 360 Cash, Barclays, Novum Cash Associates, and Third Derivative. 

How the CO2 Battery works

CO2 is 1 of the few gases that can be condensed and stored as a liquid under pressure at ambient temperature, so, as Power Dome states on its web page, it is the ideal fluid to retailer energy price-efficiently in a shut thermodynamic approach. It lets for superior-density electrical power storage devoid of the need to have to go to incredibly low temperatures.

Spadacini described how it operates to Bloomberg in May possibly:

To cost the battery, we acquire CO2 at close to atmospheric temperature and pressure and we compress it. The heat that is created during compression is stored. When we trade the thermal energy with the ambiance, the CO2 gas becomes liquid.

To make and dispatch electrical power, the liquid CO2 is heated up and converted again into a gasoline that powers a turbine, which generates ability. The CO2 gasoline is often contained and the entire method is sealed.

We never use any exotic resources. The engineering uses steel, CO2 and h2o. So there is no dependency on uncommon earth products like cobalt or lithium. This makes our engineering geopolitically impartial. It can be created everywhere and it can be applied all over the place.

Electrical power Dome produced a limited movie final year demonstrating how its CO2 energy storage will work:

Electrek’s Consider

June 28 update: This is an incredibly thrilling innovation, and the actuality that Energy Dome now has the funds to deploy its professional products for A2A is a very significant deal. We can not wait to see what will come subsequent.


This is undoubtedly one particular to look at, as a CO2 battery doesn’t use uncommon earth resources, and which is a quite big offer. It would seem value-efficient and downright democratic. This battery has fantastic potential, and we glimpse forward to looking at irrespective of whether it deploys rapidly on a world-wide scale.
