Agreement supports Google’s 2030 carbon-free energy goal.
CO2 Battery enables 8-24 hour energy dispatch for grid reliability.
Google invests in Energy Dome to scale long-duration storage.
Projects planned in Europe, America, and Asia-Pacific regions.
Technology stabilizes grids with natural inertia from machinery.
The partnership between Energy Dome and Google marks a significant step in delivering scalable, carbon-free energy. The CO2 Battery stores solar and wind energy for 8 to 24 hours, addressing the intermittency of renewables. This ensures reliable, cost-effective electricity for large energy users like Google, supporting its ambition to achieve 24/7 carbon-free operations by 2030.
Energy Dome’s CO2 Battery uses off-the-shelf equipment in a modular, site-independent design, avoiding supply chain constraints. Capable of dispatching energy for extended periods, it meets baseload and flexibility needs. The technology also provides grid stability through mechanical inertia, countering the loss of inertia from decommissioned fossil-fuel plants.
“Google is committed to powering our operations with clean energy, and Energy Dome's technologically proven and scalable long-duration energy storage solution can help us unlock rapid progress,” said Maud Texier, Director of EMEA Energy at Google. “But this isn’t just about Google. By helping to scale this first-of-a-kind LDES technology, we hope to help communities everywhere gain greater access to reliable, affordable electricity and support grid resilience as we integrate more renewable energy sources.”
The agreement targets CO2 Battery projects across Europe, America, and Asia-Pacific, with a pipeline of sites already in development. This rapid deployment aligns with Google’s sustainability goals and Energy Dome’s mission to provide cost-effective, carbon-free energy solutions at scale.
“The programmatic and strategic deployment of our technology at scale to help Google reach carbon-free energy represents the core of our industry-first agreement. We’re proving that a 24/7 cost-effective and carbon-free energy supply is achievable with the right technology and partnership model,” said Claudio Spadacini, Founder and CEO of Energy Dome. “We are also pleased to welcome Google as an investor in Energy Dome, underlining our joint commitment to a shared vision.”
Google’s investment in Energy Dome supports the company’s growth phase, with projects already contracted with partners like Alliant Energy, Engie, and NTPC. This backing strengthens Energy Dome’s ability to commercialize its proven technology, benefiting communities and economies by enhancing access to reliable, renewable energy.
This partnership positions Energy Dome and Google as leaders in the transition to a carbon-free energy future, driving innovation and grid resilience worldwide.
Energy Dome is at the forefront of redefining long-duration energy storage with its CO2 Battery. The properties of carbon dioxide allow the system to store energy efficiently and cost-effectively through a patented thermo-mechanical process, hence representing the most valid alternative to lithium-ion batteries or pumped-hydro solutions. The CO2 Battery is already a fully validated and cost-effective system that uses no lithium or rare-earth elements to store electricity, boasting superior round-trip efficiency. With a modular approach and site-independent footprint, CO2 Batteries use readily available, off-the-shelf components from reliable, existing supply chains, providing a scalable pathway to store massive amounts of intermittent renewable energy and accelerate the energy transition; it’s the only technology available today offering the right combination of efficiency, cost, scalability and that’s viable globally.
