On July 25, 2025, reported that Energy Dome, known for its innovative long-duration energy storage systems, entered into a commercial agreement with Google to supply zero-emission power for the tech giant’s European data centers.

Energy Dome’s proprietary technology stores excess renewable energy using compressed CO₂ in modular domes, then dispatches it when needed—providing clean, stable electricity that sidesteps the intermittency problems of solar and wind power. This is one of the first direct utility-scale partnerships between a hyperscaler (Google) and a next-gen storage provider in the EU.

The agreement supports Google’s ambition to run its data centers entirely on carbon-free energy by 2030, and reinforces its leadership in sustainable infrastructure as AI-driven compute demand continues to rise.

Key Highlights

• Zero-emission power supply for European Google data centers

• Energy Dome’s CO₂-based storage tech offers 10-hour duration dispatch

• First-of-its-kind corporate deal in EU energy storage sector

• Supports Google’s 24/7 carbon-free energy goal by 2030

• Modular & scalable: System can be deployed near data centers without major grid upgrades

Why This Matters

1. Data center sustainability: Mitigates the environmental impact of exponential compute growth.

2. Energy innovation validation: Reinforces long-duration storage as a viable alternative to lithium-based batteries.

3. EU energy resilience: Helps stabilize grids amid the transition to renewables.

4. Global signal: Encourages other hyperscalers (e.g., Microsoft, Amazon) to explore similar models.
