Theater performance and panel discussion

On 30 October 2024, Clean Circles together with several Collaborative Research Centres at TU Darmstadt will present the play “Curie_Meitner_Lamarr_indivisible” by portraittheater Wien. The play is based on the biographies of Marie Skłodowska Curie, Lise Meitner and Hedy Lamarr. A subsequent panel discussion will focus on historical perspectives of gender equality in science.

Simulation game illustrates the complexity of sustainable development

As part of this year's Clean Circles PhD student seminar, PhD students came together at the Technical University of Darmstadt to present and discuss current research findings and gain an interactive insight into the complexity of sustainability goals. In addition to presentations and laboratory visits, the Sustain2030 simulation game was a particular focus.

New research results presented in Milan

The renowned Combustion Institute conference takes place every two years. At the end of July, combustion researchers from all over the world gathered in Milan (Italy) under this year's motto “Emphasizing Energy Transition”.

Will metals complement hydrogen as the energy carrier of the future?

On Thursday, July 25, Till Mansmann (FDP), Member of the German Bundestag and Innovation Commissioner of the Federal Ministry of Education and Research, visited innovative hydrogen projects from the Energy + Environment (E+E) research field on the Lichtwiese campus at TU Darmstadt.

Summer semester ends with a simulation of EU Decision-Making

Students from Johannes Gutenberg University Mainz (JGU), Technical University of Darmstadt, Ben-Gurion University of the Negev, and various partner universities from the European university alliance FORTHEM, gathered at the end of the summer semester 2024 2024 to simulate the legislative processes of the European Union.

Iron as the key: innovative technology for the long-term storage of green energy

On 15 June 2024, the Hessian Minister of Economic Affairs, Kaweh Mansoori, visited the Clean Circles project at the Technical University of Darmstadt, in which researchers are investigating the use of iron as a CO2-free energy carrier and fuel. This innovative technology enables the safe and efficient storage of large amounts of energy and could revolutionise the use of existing coal-fired power plants.

Article in Handelsblatt focuses on alternatives to hydrogen and reports on our research

Chemical energy carriers are necessary to store renewable energy in the long term. Unlike batteries, for example, substances such as hydrogen, e-fuels and iron can store energy for any length of time. In an article in Handelsblatt, Clara Thier takes a closer look at energy storage in metals and chemicals such as sulphur or lime. It also reports on our research into iron as an energy source and the retrofitting of existing infrastructures.

Niklas Kolorz reports on Clean Circles on YouTube

60,000 CPU cores, 563 terabytes of main memory (RAM) and millions of simulated iron particles. The Lichtenberg II supercomputer at TU Darmstadt's high-performance computing center works diligently on the scientific breakthroughs of tomorrow – always accompanied by the steady whirring of the cooling system.

Poster sessions, discussions, talks and teamwork

The annual Clean Circles retreat took place in Weinheim on 6 March 2024. During the retreat, the researchers presented and discussed the status of the project and iron as an energy carrier.

Clean Circles at the HIGHEST Club on 7 March 2024

On 7 March 2024, we presented our concept of energy storage in iron and its socio-economic perspective at the HIGHEST Club evening.
