Research on Energy involves the development, characterization and application of polymeric and heterogeneous membranes for industrial separations to increase energy efficiency. Important applications are in gas and vapor separations, such as CO2 capture, but also natural gas sweetening, biogas upgrading or the removal of hazardous trace components (including CO and H2S). Also the utilization of membranes in the dairy, food and biorefinery industry offers significant energy savings, while at the same time it guarantees operation under mild conditions. Hybrid processes combining e.g. chemical conversions or reactions and separation are investigated as well, e.g. CO2-to-product.
