Ørsted and Energy Dome team up on CO2 Battery energy storage facilities

Offshore wind developer Ørsted has signed a memorandum of understanding (MoU) with Energy Dome, an energy storage solution provider, to run a feasibility study on the deployment of a 20MW / 200MWh energy storage facility.

The partners plan to deploy the energy storage facility using Energy Dome’s CO2 Battery technology on one or more Ørsted’s sites.

The partnership aims to use long-duration energy storage to provide baseload renewable energy to Ørsted’s end-use customers, mitigating the growing variability in energy supply, and providing grid stability services.

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 during the second half of 2024.

The feasibility study project with Ørsted, which will dispatch renewable energy over periods of 10 hours or longer, is said to be a milestone in Energy Dome’s roadmap for the development of multiple commercial CO2 Battery energy storage facilities. 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.

For Ørsted, testing the CO2 Battery energy storage project is part of the company’s plan to provide a comprehensive flexible solution that increases both the availability and reliability of green energy also with the aid of long-duration energy storage.

Kieran White, VP of Europe Onshore at Ørsted, said: “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.

“We consider the CO2 Battery solution to be a really promising alternative for long-duration energy storage. This technology could potentially help us decarbonise electrical grids by making renewable energy dispatchable.”

Claudio Spadacini, founder and CEO of Energy Dome, commented: “We are thrilled to collaborate with Ørsted, …, on our shared vision of deploying as much energy storage as possible to enable 100% renewable energy on the grid. Energy Dome looks forward to helping Ørsted achieve their renewable energy and energy storage goals as they expand into new markets.”
