September 30 (Renewables Now) - Danish clean energy major Ørsted A/S (CPH:ORSTED) to probe the potential for building a 20-MW/200-MWh energy storage facility at one of its sites, using the CO2 technology of Italian long-duration energy storage firm Energy Dome SpA.
The duo has signed a memorandum of understanding (MoU) for a feasibility study on the project, it said earlier this week. The pact paves the way for a wider partnership under which Energy Dome’s carbon dioxide (CO2) battery technology will be deployed at some of Ørsted's European plants to provide baseload renewable energy to its end-use customers.
Under the plan, projects for one or multiple battery storage are to be developed.
The first scheme in the initiative calls for the installation of a 20-MW unit, the construction of which is planned to begin in the second half of 2024. The facility will have more than 10 hours of storage capacity.
“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,” said Kieran White, vice president Europe Onshore at Ørsted.
Energy Dome’s process uses CO2 as a working fluid in a closed loop to store renewable energy for up to 24 hours and send it to the grid when needed. The company completed its 2.5-MW/4-MWh commercial demonstration plant in Sardinia, Italy, in June and is working to accelerate the technology's commercial deployment.
