Iron has enormous potential to boost the energy transition. The project Clean Circles teams up scientists from multiple disciplines to explore how the metal and its oxides can be used in a cycle as carbon-free chemical energy carrier to store wind and solar power.

Clean Circles annual retreat 2023
Poster sessions, discussions, talks and teamwork
The annual Clean Circles retreat took place in Seeheim on 27–28 February 2023. During the retreat, the project leaders and their scientific staff were able to discuss the status of the project and its future.
Seminar: Towards Carbon-neutral Energy and Processes
Review talks and scientific discussions
On the occasion of the 70th birthday of Prof. Dr. Katharina Kohse-Höinghaus, Clean Circles organized in close collaboration with the CRC/TRR 150 the seminar Towards Carbon-neutral Energy and Processes.
First Datathon on research data management
Event in cooperation with the Collaborative Research Centres 1194 and Transregio 150
The first Clean Circles Datathon took place on 8 February 2023. The topic was how research data management according to the FAIR principles looks like in practice and how it can be implemented.
The development of the German hydrogen policy discourse
New publication in Energy Research and Social Science
Hydrogen is still a niche technology in Germany. Until now, the relatively young public debate on hydrogen policy has also hardly been polarised and conflict-ridden. Michèle Knodt from the Institute of Political Science at TU Darmstadt and colleagues from Masaryk University in Brno (Czech Republic) used a discourse network analysis to investigate how the composition of the actors, their positions and the general discourse structure in Germany have developed. The results were published in the journal Energy Research and Social Science.

Political and economic assessment of green energy imports
Mini symposium of Research Area 4 (Political-economic analysis)
On 04 July 2022, Clean Circles scientists and speakers from Potsdam, Erfurt and Hamburg discussed political and economic indicators for assessing green energy imports.
Minisymposium on research area 3 (thermodynamic-mathematical analysis)
30 May 2022, 2:00 p.m.
We cordially invite you to the 2nd Clean Circles Mini-Symposium on 30 May 2022. The meeting will be held at 2:00 p. m. via Zoom. The symposium will feature one talk by a distinguished scientist in the field of thermodynamics and energy storage. It will be followed by two talks on recent advances in the thermoeconomic assessment of iron and the modeling and optimization of logistic networks within Clean Circles (PIs Stephan and Pfetsch). The duration of the symposium is approximately 2 hours, a detailed agenda is provided below. Each part will comprise a presentation followed by a short discussion.
Clean Circles is funded by the Hessian Ministry of Higher Education, Research, Science and the Arts.
