Iron as a reactive metal 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.

The Making of a Serious Game about the Energy Carriers of Tomorrow
How do you tell the story of research and studying in a way that feels like an adventure? That question marked the beginning of a side project that would lead us far beyond our usual roles: into voice acting, video editing, music direction, storyboarding, dialogue writing, game and puzzle design, and even the visual styling of virtual worlds.

Four Years of Research at the End-of-Project Meeting in Karlsruhe
At the final meeting of the Clean Circles research project, researchers gathered at the Karlsruhe Institute of Technology (KIT) to reflect on four years of collaborative work. The event featured presentations that not only reviewed past achievements but also looked ahead to upcoming projects and future challenges – with iron as a CO₂-free energy carrier at the center.
Clean Circles is funded by the Hessian Ministry of Higher Education, Research, Science and the Arts.
