Dutch water technology for sustainable energy storage

In 2014, five passionate engineers came together in the Netherlands, connected by a shared ambition to reduce the pollution and waste of mainstream batteries. The co-founders recognized the urgent need for sustainable energy storage to enable a renewable grid. For the next three years, they combined their expertise in water technology and energy science to build AQUABATTERY’s first prototype: a flow battery using solely table salt and water. Our solution is key to securing a net-zero power system without the need for critical raw materials. By relying on abundantly available and environmentally friendly materials, AQUABATTERY is safe for people and the planet.

Dutch water technology for sustainable energy storage


To meet the challenge set by the Paris Climate Agreement and keep global temperature rise under 1.5°C, the world is rapidly expanding solar and wind generation. By 2025 our team will deliver AQUABATTERY’s flagship energy storage unit to meet this challenge head-on. We use the power of entrepreneurship, supported by the European Innovation Council, to provide everyone with clean, renewable electricity anywhere, at all times.

Commercialising the world’s first saltwater flow battery requires constant innovation and cutting-edge science. We take our company culture as seriously as our mission and build our strength on diversity, bold action and pushing the boundaries of sustainable energy storage. To date, our team has successfully built three AQUABATTERY pilots.
