Google and Energy Dome Advance Multi-Continent Energy Storage Buildout with First Bilateral Project in Ireland

The 23MW/200MWh CO2 Battery project marks the first bilateral commercial agreement between the companies, relieving grid congestion, promoting energy security and accelerating a 24/7 carbon-free energy solution in Ireland and beyond

Today Energy Dome, a leading long-duration energy storage technology developer, and Google announced their first bilateral commercial contract for a 23MW / 200MWh CO2 Battery project located in County Offaly, Ireland. The project is part of a long-term partnership the companies announced last year to deploy Energy Dome’s CO2 Battery technology at scale and advance Google’s ambition to expand access to affordable, secure and 24/7 clean energy for grids globally. This announcement is on the back of a 19 MW/200 MWh project in Arizona announced this month by Energy Dome, Google, and the local utility SRP.

This project will be developed, owned and operated by Energy Dome using its proprietary CO2 Battery technology. The technology works by using grid power to compress and store CO2, then, when power is needed, expanding the CO2 through a turbine to generate energy that is sent back to the grid.
