R&D: Redox Flow Extrusion: New process technology

With demand for energy storage solutions rising rapidly in connection with the transition to renewables, the companies thyssenkrupp, Centroplast and Eisenhuth & the research institutes Energie-Forschungszentrum Niedersachsen (EFZN) and Zentrum für BrennstoffzellenTechnik (ZBT) have launcheda joint research and development project. The aim is to develop a new, low-cost process to manufacture one of the core components of redox flow batteries – bipolar plates – with surface areas in the m² range.

The new technology will substantially reduce the unit manu-facturing costs of redox flow batteries and is expected to be marketed by thyssenkrupp from 2018
