Reconnecting materials and energy
Clean Circles researchers at the Heraeus seminar
2022/11/07
Researchers from the Clean Circles project participated in the 773rd Seminar of the Wilhelm and Else Heraeus-Stiftung with presentations and poster contributions. The event took place in Bad Honnef from 23 to 27 October 2022 under the topic “Materials and Energy – New Directions for the Energiewende”.
The seminar was also attended by scientists from other research projects that also focus on metals as energy carriers for various applications, and there was an opportunity for mutual exchange about future synergies with Clean Circles.
The programme included lectures by renowned researchers such as Prof. Linda Nazar (University of Waterloo, Canada), Prof. Jeffrey Bergthorson (McGill University, Canada) or Prof. Dierk Raabe (Max Planck Institute for Iron Research). They informed the participants about the current state of research in the fields of circular economy, metallic energy sources, environmentally friendly steel production or high-energy battery technology.
The Clean Circles team would like to thank the organisers and the Heraeus foundation for the successful and informative seminar.
The Wilhelm und Else Heraeus-Stiftung is a private foundation that supports research and eduction in science with an emphasis on physics. It is recognized as Germany's most important private institution funding physics. Some of the activities of the foundation are carried out in close cooperation with the German Physical Society (DPhG).
