The Netherlands – Norwegian renewables company Statkraft and Dutch climate tech start-up Aquabattery are joining forces to advance Long Duration Energy Storage (LDES) through a revolutionary flow battery technology utilizing saltwater.
The primary goal of the Statkraft-Aquabattery partnership is to develop and test a pilot for Aquabattery’s LDES flow battery technology in Delft, The Netherlands. This innovative approach has the potential to redefine long-duration energy storage, crucial for creating a sustainable and stable global energy system. The partnership aligns with Statkraft’s commitment to accelerating the green transition and meeting renewable energy capacity targets.
Aquabattery’s LDES flow battery relies on a combination of table salt and water for energy storage. This technology represents a significant advancement in the field of battery energy storage, offering a duration exceeding six hours. In comparison, current large-scale battery systems typically provide energy storage for one to four hours.
Long Duration Energy Storage is poised to play a pivotal role in overcoming challenges associated with peak and low generation hours, grid congestion, and costly infrastructure investments. By contributing to grid stability, the technology supports the integration of renewable sources like wind and solar, facilitating a smoother transition away from fossil fuels.
