Flow Batteries – Current State of Developments
Adj Associate Professor Jens Noack, University of NSW
Redox flow batteries are one of the most promising options for storing excess energy for storage periods of a few hours or more for renewable energy sources. RFBs store electrical energy with the help of electrochemical cells in flowing media, thus enabling a separation of scaling of power and energy . To date, an almost unmanageable variety of different redox pair combinations have been investigated within 70 years, but only a small number have been commercialised. These include in particular the well-known vanadium/vanadium redox flow battery, zinc-bromine, iron-chromium and more recently iron/iron redox flow batteries and various types of RFBs based on aqueous organic electrolytes. In the last decade, the development of RFBs, and especially organic-based ones, has intensified significantly.
This has been accompanied by a significant shift in the development focus of the different technologies due to the achievement of higher technological readiness levels (TRLs). While VRFBs are now commercially available in almost all size classes and the focus of developments is on cost optimisation and production technologies in particular, other, especially newer technologies have the potential for extremely low-cost medium- and long-term storage, but also have to overcome a variety of challenges in some cases. In this presentation, we will give an overview of the most important flow battery technologies, the state of development and their properties and perspectives.
Jens Noack studied chemical engineering and environmental technology at the Dresden University of Applied Sciences and recieved his PhD from Karlsruhe Institute of Technology. Since 2007, he has been working at the German Fraunhofer Institute for Chemical Technology in the Department of Applied Electrochemistry, where he has mainly been involved in the development of redox flow batteries as storage for renewable energy.
Since 2020 he is an Adjunct Associate Professor at the University of New South Wales in Sydney/Australia and since 2024 at the Australian Institute for Bioengineering and Nanotechnology (AIBN) at The University of Queensland in Brisbane / Australia. Since 2023 he is also a guest lecturer at the University of the Bundeswehr in Munich / Germany.
His research and development focuses on differnet kinds and aspects of flow batteries for the storage of renewable energies. He is the deputy Director and the German project lead of the German-Australian Alliance for Electrochemical Technologies for Storage of Renewable Energy (CENELEST) and project lead of the EU Marie Skłodowska-Curie European Doctoral Training Network PREDICTOR.
Jens Noack is the author of over 100 publications, including 57 peer reviewed papers, 29 patent applications and three review articles. He has also given over 70 talks at conferences worldwide, including several invited talks. He is a member of the scientific committee of the International Flow Battery Forum since 2016 and a member of several national and international standardisation committees and other professional organisations.
