Overview

• The agreement includes an undisclosed strategic investment by Google to back Milan-based Energy Dome’s long-duration CO₂ storage solution.
• Energy Dome’s system compresses and liquefies carbon dioxide then re-expands the gas through turbines to dispatch carbon-free electricity for 8–24 hours.
• This partnership marks Google’s first commercial venture into long-duration energy storage and extends its clean energy portfolio beyond short-duration lithium-ion batteries.
• A development pipeline spanning Europe, the United States and Asia-Pacific is advancing through site selection and contracting, with Wisconsin regulators recently approving one project and offtake deals in place with Engie and Alliant Energy.
• Google expects these deployments to bolster grid resilience, reduce reliance on critical minerals and edge it closer to round-the-clock carbon-free power by 2030.
