ENERGY STORAGEDATA AND AI INFRASTRUCTURE

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.
