Dutch large-scale electricity storage company Elestor and Windpark Zeewolde B.V., owner of the Zeewolde Wind Farm, the largest onshore wind farm in the Netherlands, have announced that they will collaborate on the phased deployment of a hydrogen-iron flow battery. The long-duration energy storage system will be directly connected to the wind farm to improve the use of renewable electricity and optimize available grid capacity.
The planned installation will have a power capacity of 20 MW and is designed to provide between 10 and 40 hours of storage, resulting in a total capacity of 200 to 800 MWh.
Phased deployment
The project will start with the installation of Elestor’s final pre-commercial hydrogen-iron flow battery to demonstrate the technology’s performance and market readiness under operational conditions. A commercially ready production battery is planned to follow.
The 322 MW Zeewolde Wind Farm, located in the Dutch province of Flevoland and fully commissioned in 2022, is owned by more than 200 local farmers, residents and entrepreneurs. The addition of long-duration storage is seen as the next step in its development into an energy hub combining renewable generation, storage and flexible energy use.
Commercial milestone
For Elestor, the project marks an important step towards the commercial deployment of its hydrogen-iron flow battery technology. The system is designed for long-duration storage and frequent cycling using abundant materials, including hydrogen and iron.
The partners say the project will demonstrate how long-duration energy storage can support large-scale wind generation by storing renewable electricity when production is high and making it available when demand increases or grid capacity allows. Source (including image): Elestor
