Redox flow battery firm JenaBatteries is cooperating with BASF to develop an electrolyte that can be used in grid-scale energy storage systems.
The German firms announced on 6 February they would produce an electrolyte that is suitable for use in a large-scale system for storing renewable energy.
Start-up JenaBatteries plans to market its first redox flow batteries (RFB) this year. The systems are scalable up to 2MW/10MWh.
JenaBatteries has developed an system that uses two liquid organic electrolytes stored in individual tanks separated by a membrane.
BASF will supply one of the two electrolytes based on an amine, a chemical intermediate the company can produce on an industrial scale.
The size of the connected and scalable tanks is the determining factor for the capacity of the RFB. They are therefore suitable for use in large-scale stationary applications with a capacity of 100kW/400kWh and above.
