A 100% sustainable and infinitely scalable electrical energy storage system

Industry: Energy

Country: Netherlands


AquaBattery is a revolutionary battery storage technology that offers an unlimited storage capacity, inexpensive scaling and is 100% sustainable. AquaBattery is based on a simple principle: input renewable energy, store it in saltwater, then return electricity when there is energy demand. The core innovation in the AquaBattery is the use of seawater as a sustainable, safe and scalable energy storage medium. This is enabled by the company’s patented membrane stack technology that utilizes electrodialysis and reverse electrodialysis for energy storage and discharge.


AquaBattery’s solution is highly scalable since energy storage is currently a global market opportunity driven by the need for decarbonization and strategic government initiatives. The successful commercialization of AquaBattery will allow for the integration of a larger share of renewables into the EU energy mix, resulting in the reduction of greenhouse gas emissions, providing both positive social and environmental impacts.
