The use of renewable energies is expected to be massively expanded in the coming years. Electricity is expected to be primarily generated from wind, water and solar energy. As the availability of these energy sources fluctuates temporarily, the focus is not only on the expansion but also on the storage of renewable energy.
The graphic on the right shows how iron can be used in an energy and material cycle: Available renewable electricity is used to reduce iron oxide to iron. The iron obtained in this way can be stored and transported as required. At times of high electricity demand, the iron is oxidized with oxygen. The thermal energy released in this process is used to generate electricity. No CO2 is emitted during this process.
The Clean Circles cluster project (link) is investigating how existing power plant infrastructure can be operated CO2-free with iron in the future.
An optically accessible swirl combustion chamber is available at the RSM Institute. The stabilization of iron dust flames is investigated in this combustion chamber. Laser-based optical measurement techniques are used at the RSM to perform investigations on the iron dust flame with high temporal and spatial resolution. These measurement techniques are non-intrusive and thus allow the process to be studied in detail without manipulating it. The data acquired in this way are used to improve the understanding of the coupling between chemical reactions and transport processes in turbulent iron dust flames.
