    Renewable energy sources like solar cells (photovoltaics) and wind turbines require large-scale energy storage systems to balance out fluctuations in energy generation. Redox-flow batteries (RFBs) are considered to be one of the most promising solutions. RFBs store and release energy as electrons are swapped between two chemical reactants, via an electric conductor. The wide range of electroactive substances available – many of which occur in nature – means that vast numbers of potential redox-flow systems remain to be explored.

  • Energy storage systems are of crucial importance to all sectors of industry involved in the energy and mobility transition. The idea behind Germany’s ‘Forschungsfertigung Batteriezelle’ is to create a development center for battery cell production that will serve the whole of Germany. Known by its German abbreviation FFB, the new battery cell research facility will close the current gap in the value chain of primary and rechargeable batteries and eliminate the need to depend on other markets. The project team, which consists of the Fraunhofer-Gesellschaft and its research partners, is now embarking on the first steps to put the FFB concept into practice at the chosen location of Münster in the federal state of North Rhine-Westphalia.

    The global release of plastics into the environment must be stopped. The Fraunhofer Cluster of Excellence “Circular Plastics Economy” concerns itself with how plastic must be designed so that it can be recycled, degraded quickly and without residues, or, at best, not be released into the environment. At K 2019, the five Fraunhofer Institutes involved are using the example of plastics to present the research approach that should convert energy flows and mate-rial streams in a recycling chain into a circular form of economy. Hall 7, Stand SC1.
