Google Partners with Energy Dome for Carbon-Free Energy Solutions

• Google invests in Energy Dome to supply carbon-free energy for its grid operations.
• Energy Dome’s CO2 battery technology supports long-duration storage without scarce materials.
• Sardinia’s 20MW plant, set for 2024 completion, powers 13,000–15,000 homes daily.

Italian energy storage company Energy Dome announced a commercial partnership with Google to provide carbon-free energy for the tech giant’s grid operations. This collaboration includes a strategic investment from Google in the Milan-based firm, which specializes in innovative CO2 battery technology for long-duration energy storage. Financial details of the deal were not disclosed.

The partnership aligns with Google’s ambition to achieve 24/7 carbon-free energy for its global operations by 2030, marking its first commercial agreement for long-duration energy storage.

Energy Dome’s CO2-based system operates by compressing and liquefying carbon dioxide to store energy, which is later expanded to generate electricity. Unlike traditional batteries, this technology avoids scarce materials like lithium and copper, offering a sustainable solution that could enhance energy security and appeal to European policymakers aiming to reduce reliance on critical minerals.

The company’s investor base, now including Google, also features Oman’s sovereign wealth fund and global tank storage operator Vopak, reflecting strong confidence in its approach.

In 2022, Energy Dome launched its first commercial-scale facility in Sardinia, targeting completion by the end of 2024. This plant, with a 20-megawatt capacity and a 24-hour cycle, can power approximately 13,000–15,000 homes.

The partnership with Google underscores the growing role of advanced energy technologies in supporting the global transition to sustainable energy systems, positioning Energy Dome as a key player in the sector.
