    Danish renewable energy developer Ørsted will work with CO2 battery producer Energy Dome to explore possibilities for deploying the latter’s invention to support wind and solar projects in Europe.

    The partnership would study the feasibility of a 20-MW/200-MWh energy storage site using Italian-based Energy Dome’s CO2 Battery technology at one or more Ørsted renewable facilities. The agreement includes an option to develop multiple additional CO2 Battery energy storage facilities, with the potential for the first 20 MW project slated to begin construction already during the second half of 2024.

    Ørsted is looking for long-duration energy storage which could dispatch renewable energy over periods of 10 hours or longer. Most utility-scale battery storage currently is based on lithium-ion chemistry, which lacks for much duration beyond four hours, according to reports. Utility-scale energy storage is seen as a key potential solution for handling the intermittencies of renewables as well as peak demand periods without the availability of dispatchable power such as gas-fired generation. 

    The first such site will be located in Continental Europe. This milestone follows the completion of Energy Dome’s first commercial demonstration facility in Sardinia, Italy.

    “As a company focused on quickly scaling the build-out of wind, solar, Power-to-X and other renewable energy solutions, we are delighted to work with Energy Dome to explore how we can deploy their innovative long-duration energy storage technology,” Kieran White, VP of Europe Onshore at Ørsted, said in a statement. “We consider the CO2 Battery solution to be a really promising alternative for long-duration energy storage. This technology could potentially help us decarbonize electrical grids by making renewable energy dispatchable.”

    Energy Dome’s CO2 Battery technology is based on a thermodynamic process that stores energy by manipulating carbon dioxide under different conditions in a closed system. When in charging mode, the C02 is withdrawn from a holding area and uses compression to generate heat, which is then stored, according to the company.

    The CO2 is then condensed and stored under pressure in the liquid vessels. When in discharging mode, the liquid CO2 is evaporated and heated, expanding into a reheat turbine returning power to the store, after which is stored back into the Dome without leakage, according to the company.

    This summer, Energy Dome announced it had a closed an $11 million new round of bridge funding. Investors include CDP Venture Capital, Barclays and Novum Capital Partners.
