Google Invests in Energy Dome CO2 Battery for Global Long-Duration Storage

Google has made a strategic investment in Energy Dome, an Italian startup developing innovative CO2 Battery technology for long-duration energy storage, aiming to power its data centers with clean energy around the clock by 2030. The CO2 Battery stores energy by compressing and liquefying carbon dioxide, which can later be expanded through turbines to generate electricity for 8 to 24 hours, providing grid stability and addressing intermittency issues associated with renewables like wind and solar. This technology offers advantages over lithium-ion batteries, including longer storage durations, modular and site-independent design, lower costs, and the ability to provide grid inertia services traditionally supplied by thermal power plants. Google’s partnership with Energy Dome spans multiple global regions including Europe, the Americas, and Asia-Pacific, with several projects already in development or contracting stages alongside other partners such as Alliant Energy, ENGIE, and NTPC. The integration of AI optimizes the battery’s performance, predictive maintenance, and grid coordination, enhancing efficiency and extending the system's lifespan. This collaboration reflects Google's broader commitment to achieving 24/7 carbon-free energy operations and supports the evolving energy transition by combining advanced storage solutions with artificial intelligence.
