Tuesday 20st of June we had our last General Asssembly Meeting of the project SONAR. The meeting took place in the facilities of DTU in Copenhagen / Denmark.
In order to achieve a successful broad market entry of redox flow batteries, not only the technical performance but also the economic efficiency of the system is important. Known flow batteries must therefore be optimized techno-economically for specific applications. Not every technically possible improvement has the same positive influence on the economically relevant performance or energy-related specific costs. With the help of an optimization potential as a value, prioritizations of the optimization approaches possible in concrete cases can be obtained. Extensive comparative measurements on redox flow batteries based on vanadium and on methyl viologen and TEMPO served to establish a data basis for all input values for the model presented here. The data came from measurements of laboratory batteries, since only from these real numerical values for the costs could be obtained. The theoretical model developed in this way can be used as a profound basis in other investigations with e.g. industrial batteries in order to be able to carry out goal-oriented optimization and more realistic comparisons.

This one day workshop addresses the modelling approaches and simulation techniques developed in SONAR to capture the physical processes within and around a redox flow battery. Besides the introduction of the most important concepts, this course provides several presentations, live demonstrations, and practical hands-on sessions.
In August, we will offer the course “Fundamentals and Design of Electrochemical Energy Storage Systems” in term 2C for the first time. The course lasts four weeks and includes a practical training to learn more about the functioning of different storage systems, especially for the future market of stationary storage systems for renewable energy. Enrolment is now open for all UNSW students:
Jens will give a talk about flow batteries at the 35th topical meeting at the Gold Coast in Australia between 7 – 10 th May 2023.
