Google Launches CO2 Battery Plant in Sardinia for Long-Duration Renewable Energy Storage
Google has launched its first CO2 battery plant in Sardinia, utilizing 2,000 tons of carbon dioxide to generate 20 megawatts of power for 10 hours, as part of its long-duration energy storage initiative. This technology, developed in partnership with Energy Dome, is expected to be 30% cheaper than lithium-ion batteries and aims to support Google's data centers amid rising emissions. Future projects are planned across Europe, the U.S., and the Asia-Pacific region, with global partnerships expanding the deployment of CO2 battery solutions.

Google has initiated its first CO2 battery plant in Sardinia as part of its commitment to long-duration energy storage (LDES). This facility utilizes 2,000 tons of carbon dioxide to power a turbine generating 20 megawatts for 10 hours, enabling the storage of excess renewable energy.
Future projects are planned in Europe, the U.S., and the Asia-Pacific region utilizing technology from Energy Dome. Despite aiming for carbon neutrality by 2030, Google reported a 48% increase in emissions due to AI demands on data centers, with energy consumption from these centers exceeding 30.8 million MWh in 2024.
Google plans to deploy CO2 battery technology across its major data centers. Energy Dome's solution is anticipated to be 30% cheaper than lithium-ion batteries, offering a longer lifespan and minimizing reliance on critical minerals. Additionally, partnerships are forming globally, including a CO2 battery project by NTPC Limited in India and another by Alliant Energy in Wisconsin, targeting energy provision for data centers.
