Storing renewables

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.

How is that going to work?

Research partners

Clean Circles project teams up researchers from TU Darmstadt, Darmstadt University of Applied Sciences, University of Mainz, Karlsruhe Institute of Technology and the DLR Institute of Low-Carbon Industrial Processes in Cottbus.



Clean Circles is funded by the Hessian Ministry of Higher Education, Research, Science and the Arts.
