The strong expansion of renewable energies is already causing demand for energy storage systems to increase. Their production, in turn, depends on raw materials such as vanadium, which could not previously be substituted. Although domestic industrial residues also have a relevant vanadium content, most of the raw material is currently imported. The joint project “VAFLOW“ is, therefore, investigating and developing new ways of using vanadium-containing residues from domestic industry. In doing so, the researchers are particularly considering residual materials that have not yet been the focus of attention for vanadium recovery and electrolyte production.
Linking of the energy transition and raw materials shift
The “VAFLOW“ joint project is developing processing methods for vanadium-containing residual materials for use in redox flow battery storage systems. Industrial raw materials will thus ideally not only be used much more efficiently. The extracted recyclable materials will also be converted as electrolytes into a concrete application for the energy transition. In this way, the joint project addresses the energy transition and raw materials shift in equal measure. The project team is pursuing an interdisciplinary approach for the targeted screening of various industries in which the relevant residual substances are produced, the analysis of these substances, and the development of new business models.
