Overview of our research interests

Bild 1 (1)

Renewable energy conversion and storage are relevant topics in applied research today, since the use of non-fossil energy sources is essential for the reduction of CO2 emissions. Solar and wind energy harvesting combined with chemical energy storage in batteries or fuels like hydrogen are essential processes, which need to be improved in efficiency, long-term stability and scalability. Our goal is to contribute to the development of cost effective scalable solutions for energy conversion and storage.
