Energy Dome gets $44M uplift into its CO2 battery for renewable energy storage

Natasha Lomas of TechCrunch reports on Energy Dome, which has raised $44 million for its CO2 battery.

The C3 Take
  • Energy Dome’s CO2 battery works in a closed-loop cycle and transforms carbon dioxide from gas to liquid and back to gas to generate heat–which is then stored or sent to the power grid.
  • The company claims that 75% of each unit of renewable energy that is stored in the system can be used for later usage.
  • Energy Dome’s system also does not require lithium to function, which makes could be especially important as global demand for lithium–and its cost–increases.

“Storage is important for renewables as major clean sources of energy generation like solar and wind power are variable, since the sun doesn’t always shine nor the wind always blow. This means, not that renewables are useless (as some right-wing politicians have tried to claim) but that decarbonizing the electricity grid using these alternative (green) sources of power requires innovation in storage tech — which is where Energy Dome is aiming to step in with its CO2 Battery.”
