Redox flow batteries at Danish Battery Symposium 2018

At the Danish Battery Symposium 2018 we will put significant focus on redox-flow batteries that due to the inherent independent scalability of the power and energy is of particular interest for large scale storage of energy. We have invited group leader of the Redox Flow Battery Group at Fraunhofer Institute for Chemical Technology Dr. Peter Fischer to give insights into vanadium flow batteries, compare this to the new and emerging flow battery technologies and discuss the future potential of each technology.

To facilitate discussions among participants and speakers, flow batteries will be one of the subjects in the 1 hour breakout session before lunch. In addition to Dr. Peter Fischer, we have invited companies and research groups in Denmark working with flow batteries to the symposium and in the breakout session it will be possible to share ideas, learnings and possible collaboration. Most of the relevant parties have already signed up for the symposium.

In Denmark, there is currently one private company, VisBlue, which is commercializing flow battery technology based on the well-known acidic aqueous vanadium electrolyte. The first installation of a large scale vanadium battery in Denmark took place in 2008, with the installation of the still operational 15 kW / 120 kWh vanadium battery at SYSLAB at Risø DTU. More info on the installation here. Today several groups at the universities of Aarhus (link), Aalborg (link) and DTU (link) are pursuing research related to flow batteries, a significant part of the academic research is devoted to flow battery chemistries relying on water soluble organic redox couples. The research carried out spans computational prediction of key properties (solubility, redox potential, stability…) of new organic redox couples, sustainable production of organic redox couples using funghi, integration of photoelectrodes for direct solar charging of flow batteries, to performance and lifetime testing at different cell and stack sizes.
