"Italian long-duration energy storage company Energy Dome, which has developed
a storage technology that uses CO₂ to store electricity, has landed an
important new backer, with global tech giant Google committing to invest in the
company and support the deployment of commercial projects around the globe.
Energy Dome, which was founded in 2020, has developed a so-called “CO2 Battery”
that relies on a thermo-mechanical cycle to charge by drawing carbon dioxide
from within a dome and store it under pressure as a liquid, then dispatch power
back into the grid by evaporating and expanding the CO₂ through a turbine back
into the dome.
The CO₂ Battery boasts round trip efficiency of over 75 per cent, slightly
lower than a traditional lithium-ion battery. But whereas a lithium battery
will see its efficiency degrade over time, the CO₂ battery will not. It is also
expected to have a lifespan in excess of 30 years and doesn’t rely on any
critical materials.
A commercial demonstration facility connected to the local grid has been
operating in Italy for over three years, as well as a more recent 10-hour 20
megawatt (MW) commercial plant."
