With Prof. 28 November 2023 with Christian Hasse, Prof. Katharina Kohse-Höinghaus and Prof. Maximilian Fleischer

What role do chemical energy storage systems play in the energy transition? Hydrogen is currently the focus of attention. Relatively new to the discussion is iron as energy carrier. On 28 November 2023, the “acatech am Dienstag” series of events will be dedicated to the topic of chemical storage options. Technological maturity, efficiency, aspects of transport and import will be discussed against the background of international energy partnerships. Panelists are Prof. Christian Hasse (Clean Circles), Prof. Katharina Kohse-Höinghaus (University of Bielefeld) and Prof. Maximilian Fleischer (Siemens Energy).

Clean Circles organizes conference on Metal-enabled Cycle of Renewable Energy (MECRE)

The 2nd International MECRE Conference will be held from 13–15 November 2024 in Darmstadt, Germany.

Frame promotion processes generated by the EU’s bet on hydrogen

In decarbonising energy-intensive sectors, the EU will continue to rely on energy imports from partner countries. In a new article, Clean Circles researchers analyse framing processes in the public discourse that have emerged since the EU's strategy shift towards hydrogen.

The International Interdisciplinary Forum on Energy and Circular Economy is an opportunity for young researchers to get involved in the unique research environment of Clean Circles accompanied by individual mentoring from experienced researchers. In this series we introduce the participants of the Forum.

Publication in “Middle East Policy”

The European Union is stepping up its cooperation with external partners in the field of energy. Researchers from the Clean Circles project have analysed the relationship between the EU and Morocco in the field of hydrogen and described economic factors as drivers for institutionalised cooperation. However, the authors also see challenges. The study was published in the journal Middle East Policy (Wiley).
