Google Partners with Energy Dome to Revolutionize Clean Energy Storage Using Carbon Dioxide

Google has joined forces with Italian firm Energy Dome to harness the potential of carbon dioxide in clean energy storage. The partnership will deploy long-duration energy storage systems (LDES) at Google's renewable energy projects worldwide. Energy Dome's CO2 Battery provides clean, dispatchable energy for up to 24 hours, using off-the-shelf mechanical components and simple physics to store electricity by compressing carbon dioxide gas into a liquid. This closed-loop process repeats as needed, providing an efficient, carbon-free way to smooth out power demand and supply.

Key Takeaways:

• Google has partnered with Energy Dome to deploy long-duration energy storage systems (LDES) at its renewable energy projects worldwide.
• Energy Dome's CO2 Battery provides clean, dispatchable energy for up to 24 hours, using off-the-shelf mechanical components and simple physics.
• The CO2 Battery stores electricity by compressing carbon dioxide gas into a liquid, which is then expanded to generate electricity.
• The closed-loop process repeats as needed, providing an efficient, carbon-free way to smooth out power demand and supply.
• Energy Dome has already proven the technology works, with a 20-megawatt, 200-megawatt-hour capacity facility in Italy operating successfully for over three years.
• Google's backing could significantly accelerate the global rollout of this technology, supporting the company's goal of operating on 24/7 carbon-free energy by 2030.
• The battery also offers another key benefit: its spinning machinery adds natural inertia to the grid, stabilizing power flow and supporting grid balancing.
• The scalability of the CO2 Battery opens the door to broader access, enabling communities worldwide to benefit from reliable electricity and improved energy security.

Statistics:

• Energy Dome's CO2 Battery can provide clean, dispatchable energy for up to 24 hours.
• The CO2 Battery stores electricity by compressing carbon dioxide gas into a liquid, offering a 200-megawatt-hour capacity.
• Energy Dome's first commercial facility in Italy has been operating successfully for over three years, demonstrating the technology's feasibility.
• Google plans to deploy LDES at its renewable energy projects worldwide, aiming to meet its goal of operating on 24/7 carbon-free energy by 2030.
