The CO2 Battery in a nutshell
-
Closed thermo-mechanical transformation
-
Manipulation of CO2 between its gaseous and liquid phase
-
CO2 warms up, evaporates, and expands, turning a turbine to generate electricity
-
Energy storage sweet spot between 8/24 hours
-
Zero CO2 emissions into the atmosphere during the entire process
-
No cryogenic temperatures and high costs that are typically associated with compressed air energy storage
-
Massive reduction of costs by storing the CO2 at ambient temperature in its liquid phase
-
Patented technology that uses only water, steel, and CO2
-
All components are readily available worldwide from multiple Tier 1 suppliers
“Energy Dome’s technology uses a thermo-mechanical cycle, charging by drawing carbon dioxide from a ‘Dome’ gasholder, storing it under pressure, and then dispatching it by evaporating and expanding the gas through a turbine back into the gasholder.”
CO2 is the solution for long-duration energy storage
At the core of our solution, there’s our patented CO2-based technology. This is the only alternative to expensive, unsustainable lithium batteries currently used for energy storage. The CO2 Battery is a better-value, better-quality solution that solves your energy storage needs, so you can start transitioning to alternative energy sources today.

Standard Solution
The CO2 Battery is widely scalable on a global level thanks to the integration of well-known industrial components in a new, efficient, and cost-effective process. It’s a model where the same identical design can be deployed anywhere in the world. Every component we choose is standard, making the CO2 Battery a very simple and more economical solution, no matter where you are—a plug-and-play plant to solve the world’s biggest problem.
“Off-the-shelf equipment, standard components, modularity, and scalability are the features that make the CO2 Battery a ready-to-go solution to support the energy transition effectively.”
Services
-
Time-Shifting: Choose the best time to regulate the flow of energy. The CO2 Battery stores 8+ hours, so you are able to pick what works best for your needs.
-
Physical Inertia: Minimize in less than 1 second the variation of the grid frequency as a consequence of a mismatch between generation (supply) and load (demand) therefore maintaining optimal flow.
-
Frequency Containment Reserve (Primary Reserve): Restore the equilibrium between generation (supply) and load (demand) within 30 seconds, at any level of frequency.
-
Automatic Frequency Restoration Reserve (Secondary Reserve): Replace FCR gradually after 30″ if the deviations persist to restore the grid frequency.
-
Manual Frequency Restoration Reserve (Tertiary Reserve): Restore the grid frequency by supporting or partially substituting aFRR after 12.5 Minutes.
-
Voltage Regulation: Restore the nominal grid voltage by varying the reactive power of the machine (over/under-stress).
