They are developing ceramic membranes with which pure hydrogen can be separated from carbon dioxide and water vapour. The hydrogen can then be used as a clean energy carrier, for example in fuel cells. The researchers have now been able to increase the efficiency of these membranes to an unprecedented level. Their research results were published in Scientific Reports (DOI: 10.1038/srep34773).
In technical systems, membranes can be used to separate gases – in a manner that is more efficient and cost-effective than with established methods. Membrane systems thus enable the separation of harmful greenhouse gases with comparatively low losses. At the same time, they also make it possible to obtain high-purity hydrogen for clean energy generation and storage, making ceramic membranes a key technology for transforming the energy sector (Energiewende).
