FLOWBEAT develops hybrid redox flow batteries that store both electricity and heat produced from renewable sources. Instead of vanadium, the batteries use aqueous electrolytes based on organic compounds that can be manufactured within the EU.
The consortium designs and tests industrially viable flow-battery systems. It optimises the electrolyte, the stack construction and the operating conditions for efficiency, durability and heat use. The resulting hybrid storage system, built from non-critical and recyclable materials, will be validated at pilot scale (kW/kWh).
Project Goals
- Design and test industrially viable flow-battery systems with aqueous organic electrolytes.
- Optimise electrolyte composition, stack construction and operating conditions for efficiency, durability and heat use.
- Increase the thermal stability of the systems so that they can also store thermal energy.
- Validate a hybrid electricity-and-heat storage system made from non-critical, recyclable materials at pilot scale.
Pinflow's Role
Pinflow is an industrial partner in the consortium led by the University of Chemistry and Technology, Prague, together with the organic-chemistry R&D company Centrum organické chemie. Pinflow contributes its expertise in flow-battery engineering. An early result is a cost-effective electrode assembly for flow-battery stacks, co-authored by Pinflow and published in Results in Engineering (2025).
