International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems 2023

At ECOS 2023 in Las Palmas, CleanCircles members presented two insightful papers on the optimisation of an iron reduction plant and advanced exergy analyses of the flash iron making process.

Bericht über die Forschung zu Energiespeicherung in Eisen

In Kolumne „Good News“ des ZDF-Journalisten Christian Dezer (Redaktionsleitung „plan b“) wird über das Verfahren von Clean Circles berichtet, erneuerbare Energien in Eisen zu speichern und so zu transportieren.

Mini symposium of Research Area Thermodynamic-mathematical Analysis on 24 July 2023

On 24 July 2023, the second Mini-Symposium of the Research Area Thermodynamic-mathematical Analysis took place. The program featured an insightful talk from Dr. Peter Viebahn and Alexander Jülich, members of the “Sectors and Technologies” research unit at the Wuppertal Institute. Additionally, two presentations from young researchers reflected current advances within the Research Area 2.

Bettina Stark-Watzinger and Angela Dorn as guests at the Lichtenberg High Performance Computer

The Federal Minister of Education and Research, Bettina Stark-Watzinger, has visited the high-performance computer Lichtenberg II at the TU Darmstadt. She was accompanied by the Hessian Minister of Higher Education, Research, Science and the Arts, Angela Dorn. The ministers learned about energy research projects made possible by the supercomputer – including Clean Circles.

Students simulate EU decision-making in Model European Mainz (MEUM) 2023

From 12–15 July 2023, the Clean Circles teams of Prof. Arne Niemann (JGU) and Prof. Michèle Knodt (TUDa) held a simulation at the University of Mainz on the legislative procedure of the European energy transition and its complexities in the European Parliament and Council.

Mini-symposium, Research Area 2

In the Mini-symposium of Research Area 2 on 11 July 2023, alternative metal fuels beyond iron were discussed with guests and researchers from Clean Circles.

Publication in “Regional & Federal Studies”

With the national hydrogen strategy, the German government has defined an initial framework for the integration of hydrogen into the energy system. At the subnational level, most of the federal states have also adopted their own hydrogen strategies. Clean Circles researcher Lucas Flath and his colleagues investigated the coherence of these strategies. The results have now been published in the journal “Regional & Federal Studies”.

News expansion sets standards in performance and energy efficiency

On 11 July 2023, the TU Darmstadt officially inaugurated the new Lichtenberg II high-performance computer. Data from Clean Circles for calculating the CO2-free cycle for storing and transporting renewable energies to Europe in iron will also be analysed via the new Lichtenberg II system.

Beitrag in Durchblick N – Magazin für Nachhaltigkeit

In Ländern wie etwa Australien, Kanada oder Chile übersteigt das Erzeugungspotential erneuerbarer Energie den dortigen Bedarf. Wie kann dieser Überschuss gespeichert und in das energiehungrige Deutschland transportiert werden? In der neuen Ausgabe von Durchblick N fasst Prof. Dr. Michèle Knodt in verständlicher Sprache zusammen, woran die Wissenschaftler*innen im Projekt Clean Circles forschen.

Mini symposium of Research Area 4 (Socio-economic Modelling)

Clean Circles researchers together with speakers involved in the policy-making of green energy trade discussed the key debates around Germany's energy transition, the implementation of global energy partnerships and policy implications on 31 May 2023.
