Flow battery technology based on organic molecules dissolved in aqueous electrolytes

Early stage

Metal-free and environmentally friendly aqueous flow battery system for large-scale energy storage

Icon of a present

The need

The energy storage technologies currently available all depend on the supply of rare, unsustainable and expensive materials, such as lithium, cobalt and vanadium, which will only increase in price as scarcity issues develop.

The solution

This innovative flow battery technology is based on organic molecules dissolved in aqueous electrolytes. As it consists of only highly abundant elements, the redox-active molecules can be efficiently synthesised on a large scale and with a very small environmental footprint compared to conventional technologies. Once an annual production scale of a few tonnes has been reached, battery prices of 150 €/kWh are expected.
