Energy Dome has formed a global commercial partnership with Google that will leverage Energy Dome's CO₂  battery technology to provide carbon-free energy to power Google's operations.

The deal represents Google's entry into commercial long-duration energy storage and is part of its strategy to achieve 24/7 carbon-free energy by 2030.

Energy Dome’s CO₂ battery technology is designed to consistently deliver energy from eight to 24 hours, providing sufficient, reliable electricity to meet both the baseload and flexibility needs of large energy consumers.

Its modular design utilises readily available equipment, circumventing supply chain issues and ensuring efficient, cost-effective energy storage.

The characteristics of carbon dioxide enable the system to store energy both efficiently and cost-effectively via a patented thermo-mechanical process, making it a highly viable alternative to lithium-ion batteries or pumped-hydro solutions.

The mechanical components of the system also contribute to grid stability by providing natural inertia through rotating machinery - crucial as the energy sector transitions from fossil fuels to renewable sources.

Google EMEA [Europe, Middle East and Africa] energy director Maud Texier stated: “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.

“But this isn’t just about Google. By helping to scale this first-of-a-kind LDES [long-duration energy storage] 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 develop CO₂ battery projects across strategic global regions, including Europe, America and the Asia-Pacific.

With a pipeline of sites and projects already in development, the agreement seeks to rapidly scale deployment to align with Google's carbon-free energy goals.

Google has also invested in Energy Dome, which is entering a phase of commercial deployment with contracted projects in the US, Italy and India.

Energy Dome founder and CEO Claudio Spadacini stated: “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.

“We are also pleased to welcome Google as an investor in Energy Dome, underlining our joint commitment to a shared vision.”

In addition to the Energy Dome partnership, Google has also recently signed an agreement with Brookfield Asset Management to procure up to 3GW of carbon-free hydroelectric capacity in the US.

The agreement includes 20-year power purchase agreements for two facilities in Pennsylvania, representing an investment exceeding $3bn and providing 670MW of capacity.
