up to German TVöD 13
Full-time (part-time possible)
The computational science work will be carried out at the DLR Institute for Future Fuels in Cologne as part of European projects. The candidate will be part of an interdisciplinary, multinational research team of chemists, physicists, chemical, mechanical and materials engineers and will have access to numerical tools and a broad infrastructure for the structural elucidation of solids available at the DLR facilities in Cologne-Porz-Wahn.
The specific calculations will focus on material and reactor requirements of different cyclic processes relevant for the use of concentrated solar power (CSP) systems as well as for industrial waste heat recovery applications. In particular, so-called "oxygen transfer" properties of oxides of multivalent metals will be investigated. These are e.g. multi-cation oxides based on perovskites such as CaMnO3, but also High Entropy Oxides (HEO) are of interest. Such materials can be reduced by heat from renewable energy sources, e.g. hot air from an air-driven solar thermal power plant or excess electricity from photovoltaics or wind power. The resulting reduced material can then be oxidised with air to generate "solar power" or industrial process heat respectively, when needed but
renewable energy sources are not available (for example at night). Current work at DLR has already shown that certain low-cost materials are not only capable of such cyclic redox operation, but can also be formed into stable reticulated porous ceramic structures (e.g. "ceramic foams"). For future commercialisation of such concepts, it is necessary to develop, through rational design from the atomic level, ceramic materials that have the potential to be formed into stable porous structures and to enable reversible cyclic redox operation with long material lifetimes.
In this respect, the main aims and objectives of the computational work are as follows:
