The CO2 Battery in a nutshell
“Energy Dome’s technology uses a thermodynamic 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.”
Who knew that CO2 could actually help the world?
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.
