Google partners with CO2 Battery long-duration energy storage startup Energy Dome

AI generated summary

Google has entered into a strategic partnership and investment with Energy Dome, an Italian startup specializing in carbon dioxide-based long-duration energy storage (LDES). This collaboration aims to leverage Energy Dome's CO2 Battery technology to facilitate large-scale carbon-free energy usage. The CO2 Battery operates through a process of adiabatic compression and liquefaction of CO2, allowing for energy storage and electricity generation in a closed-loop system. Energy Dome's technology is designed for applications requiring storage durations of 8 to 24 hours and can provide grid operators with necessary inertia services as fossil fuel plants are phased out.

This partnership marks Google's first venture into the LDES sector, complementing its existing clean energy initiatives. Google has expressed a commitment to powering its operations with clean energy and sees Energy Dome's scalable storage solution as a means to enhance grid resilience and support the integration of renewable energy sources. Energy Dome has already established a commercial demonstration project in Sardinia, Italy, and is expanding its operations with upcoming projects in the US and India, aiming to replicate its successful model across various regions.
