Energy Dome and Google Forge Groundbreaking Partnership to Advance Carbon-Free Energy at Scale
In a landmark move for the energy sector, Energy Dome, a trailblazer in long-duration energy storage solutions, has announced a strategic commercial partnership with Google. This collaboration will leverage Energy Dome’s innovative CO2 Battery technology to deliver carbon-free energy on a massive scale, powering Google’s operations while advancing global efforts to decarbonize electricity grids. Alongside this agreement, Google has also made a significant strategic investment in Energy Dome, underscoring its commitment to accelerating the deployment of clean energy technologies.
Why This Partnership Matters
Electricity is the backbone of modern life and economic growth. As the world transitions toward greater electrification, demand for reliable, affordable, and sustainable energy continues to rise. This trend is further amplified by the increasing computational needs of artificial intelligence (AI) and data centers, which are becoming critical drivers of electricity consumption.
While solar and wind power offer some of the most cost-effective and scalable ways to generate electricity, their intermittent nature poses challenges for grid stability and reliability. Long-duration energy storage (LDES) addresses this limitation by storing excess renewable energy and dispatching it when needed, ensuring a steady supply of “firm” electricity. For large-scale energy users like Google, LDES technologies such as Energy Dome’s CO2 Battery provide a pathway to meet energy demands cleanly, reliably, and economically.
This deal marks Google’s first commercial foray into long-duration energy storage—a key component of its broader strategy to achieve 24/7 carbon-free energy for all its operations by 2030. By selecting Energy Dome’s proven and market-ready solution, Google is signaling confidence in the technology’s ability to deliver at the speed, scale, and affordability required to meet ambitious sustainability goals.
The Power of the CO2 Battery
Energy Dome’s CO2 Battery stands out as a transformative innovation in the realm of energy storage. Unlike traditional lithium-ion batteries, the CO2 Battery uses a closed-loop thermodynamic process to store and release energy over extended periods—ranging from 8 to 24 hours. This capability makes it ideal for meeting both baseload and peak-demand requirements for large energy consumers.
The system’s modular design leverages readily available, off-the-shelf equipment, avoiding supply chain bottlenecks and ensuring rapid scalability. Its mechanical components not only store energy efficiently but also contribute to grid stability by providing natural inertia through rotating machinery. This feature is particularly crucial as more renewables replace legacy fossil fuel plants, whose decommissioning often results in the loss of essential grid-stabilizing inertia.
By acting as a “shock absorber” for sudden fluctuations in grid frequency, the CO2 Battery enhances overall grid resilience. This dual functionality—storing vast amounts of energy while supporting grid health—positions the technology as a cornerstone for integrating higher shares of renewable energy into the mix.
A Shared Vision for Global Impact
“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 partnership aims to deploy CO2 Battery projects across key geographical regions, including Europe, the Americas, and the Asia-Pacific. A robust pipeline of sites and projects is already in development, reflecting the urgency and ambition behind this initiative. The goal is to rapidly scale up deployment to align with Google’s 2030 target of operating entirely on carbon-free energy around the clock.
For Energy Dome, this collaboration represents a pivotal milestone. “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,” said Claudio Spadacini, Founder and CEO of Energy Dome. “We’re proving that a 24/7 cost-effective and carbon-free energy supply is achievable with the right technology and partnership model.”
Investment Fuels Growth and Innovation
Beyond the commercial agreement, Google’s direct investment in Energy Dome highlights its long-term commitment to fostering the growth of advanced energy technologies. This financial backing comes at a pivotal moment for the Milan-based startup, which is entering a phase of accelerated commercial deployment. Several high-profile projects are already underway, including collaborations with Alliant Energy in the U.S., Engie in Italy, and NTPC in India.
Google’s involvement goes beyond funding; the tech giant brings invaluable expertise and experience to the table. As an early adopter of corporate power purchase agreements (PPAs) during the nascent stages of solar and wind development, Google understands the importance of nurturing emerging technologies. Its role as both a customer and investor positions it uniquely to drive the maturation and widespread adoption of the CO2 Battery, benefiting communities and economies worldwide.
Toward a Sustainable Energy Future
The partnership between Energy Dome and Google exemplifies how collaboration between innovators and industry leaders can catalyze meaningful change. By deploying commercially proven, scalable solutions like the CO2 Battery, the two companies are paving the way for a future where clean, reliable, and affordable energy is accessible to all.
This initiative not only supports Google’s mission to achieve carbon-free operations but also contributes to the broader transition toward a sustainable energy ecosystem. As more organizations follow suit, partnerships like this one could redefine how we think about—and implement—long-duration energy storage, ultimately driving the global shift toward a carbon-neutral economy.
With bold ambitions, cutting-edge technology, and shared vision, Energy Dome and Google are setting a new standard for what’s possible in the quest for 24/7 carbon-free energy.
About Energy Dome
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.
