Google Adopts Energy Dome's CO2 Battery for 24/7 Renewable Energy

Google will deploy Energy Dome's long-duration energy storage in its global operations, starting August 12, 2025. The partnership aims to support Google's objective to operate entirely on carbon-free energy (CFE) by 2030. Energy Dome's CO2 Battery system stores energy using carbon dioxide within a closed thermodynamic loop. The process involves liquefying CO2 when excess renewable energy is available. The system then converts the liquid CO2 back into gas to generate electricity when demand is high. The CO2 Battery provides 8 to 24 hours of energy storage, which addresses the intermittent nature of renewable sources like solar and wind. This extended storage enhances grid stability to meet consistent energy needs. Unlike lithium-ion batteries, which have shorter storage durations, the CO2 Battery offers a potentially more sustainable solution. Google intends to integrate this technology into various projects across Europe, the United States, and the Asia-Pacific region. Google's investment signals confidence in the scalability of Energy Dome’s technology to facilitate a complete transition to carbon-free electricity and a reduction in its carbon footprint.
