Redox One’s Iron-Chrom Flow Batteries
Redox One’s mission is clear – to pioneer a sustainable energy future through safe, innovative, and cost-effective power storage solutions. They achieve this with their groundbreaking Fe-Cr Redox Flow Battery technology, which is revolutionising the way we harness and store energy.

Solar Panel Integration Vanadium Redox Flow Battery Installation in Spain
Our Member Largo Clean Energy has deployed a 6.1 MWh Vanadium Redox Flow Battery for Enel Green Power España, located in Mallorca, Spain. Read more about it here.

The Volterion Stack
Volterion has redefined the design and production standards for flow battery stacks, based on an in-house developed bipolar plate and an innovative manufacturing process. Due to a completely new design and manufacturing principle, they no longer need leak-prone seals or heavy and cost-intensive steel endplates for their stacks. Learn more.

The first Nordic agricultural flow battery installed in Norway
The agricultural battery is the first in the Nordic region, and will contribute to increased utilization of self-produced electricity, back-up power and facilitate increased future electrification of farm operations. The goal with the pilot project is to sell multiple flow batteries to buildings with their own solar cell production in Norway, Sweden and Finland. Learn more about it here.
