Google Partners With Energy Dome to Deploy CO2 Battery Storage Globally

Google has announced a global commercial partnership with long-duration energy storage provider Energy Dome to deploy its CO2 Battery technology to support carbon-free electricity for the grids powering Google’s operations. Alongside the commercial agreement, Google has also made a strategic investment in Energy Dome.

Google’s First Commercial Deal

The agreement represents Google’s first commercial deal for long-duration energy storage and forms part of its broader portfolio of advanced energy technologies aimed at achieving its ambition of running operations on 24/7 carbon-free energy by 2030.

Google said the selection of Energy Dome’s CO2 Battery technology reflects its ability to be deployed at the required scale, speed, and affordability on a global basis.

According to Energy Dome, the CO2 Battery can continuously dispatch energy for durations ranging from 8 to 24 hours, enabling it to meet both baseload and flexibility requirements of large electricity consumers.

Technology Designed for Scalable Deployment

Energy Dome stated that its CO2 Battery features a modular, site-independent design that uses off-the-shelf equipment, helping avoid supply chain bottlenecks and supporting rapid scalability.

“The modular, site-independent product design uses off-the-shelf equipment without supply chain bottlenecks, ensuring a highly scalable solution to store massive amounts of energy efficiently and cost-effectively,” the company said.

“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.

Global Project Pipeline Identified

The commercial agreement aims to develop CO2 Battery projects across key strategic geographies, including Europe, the Americas, and the Asia-Pacific region.

A pipeline of sites and projects has already been identified under the partnership, with developments currently at the contracting and development stages. The deployment is intended to scale rapidly in line with Google’s 2030 carbon-free energy objectives.

Investment Alongside Commercial Collaboration

In addition to the commercial alliance, Google has made an investment in Energy Dome as the company enters a growth phase of commercial deployment.

Energy Dome has multiple projects already contracted, including with Alliant Energy in the United States, Engie in Italy, and NTPC in India.

Commenting on the partnership, Claudio Spadacini, Founder and CEO of Energy Dome, said the agreement demonstrates the potential for achieving round-the-clock clean energy supply 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,” he said.

CO2 Battery Technology

Energy Dome said its CO2 Battery is a fully validated and cost-effective long-duration energy storage system that does not rely on lithium or rare-earth elements.

The system stores electricity using a patented thermo-mechanical process based on the properties of carbon dioxide and is positioned as an alternative to lithium-ion batteries and pumped-hydro storage solutions, with superior round-trip efficiency.
