Nataliya Roznyatovskaya et al. published a new paper on studies about the “power drop effect” in vanadium redox flow batteries. Free acid content in electrolytes for vanadium redox-flow batteries is a hardly accessible parameter in practice. If it can be roughly linked to electrolyte conductivity within the series of electrolytes with varied free acid content, such reversible or irreversible degradation phenomena as „power drop“ effect during discharge and thermally-induced aging of catholyte are shown to be dependent on electrolyte acidity. https://onlinelibrary.wiley.com/doi/full/10.1002/ente.202000445
Members of CENELEST have for the second time written an article for PV-Tech Power about redox flow batteries. While the first part was about redox flow batteries in general, the second part is specifically about vanadium redox flow batteries.

Maria gave in interesting interview for the ATSE. If you want to know more about what is behind the discovery and early development of the Vanadium Redox Flow Battery read here: https://www.atse.org.au/news-and-events/article/the-accidental-engineer-who-created-the-vanadium-sustainable-battery/
The International Bureau is a part of the German project management agency DLR-PT and responsible for CENELEST. Via DLR-PT CENELEST is recieving funding from the German Ministry for Education and Research (BMBF) to establish this international collaboration between Germany and Australia for the years 2017-2022. All those involved in establishing the joint research presence thank the help of the International Bureau, DLR-PT and BMBF and are looking forward to further fruitful cooperation and excellent results through CENELEST.
As energy storage becomes an increasingly integral part of a renewables-based electricity system, new technologies are coming to the fore. Jens Noack, Nataliya Roznyatovskaya, Chris Menictas and Maria Skyllas-Kazacos from CENELEST, a joint research venture between the Fraunhofer Institute for Chemical Technology and the University of New South Wales, chart the rise of redox flow batteries, a promising alternative to lithium-ion-based systems.
