Tailor-made membranes for the environment

The combustion of fossil energy carriers in coal and gas power plants produces waste gases that are harmful to the environment. Researchers are working on methods to not only reduce such gases, but also utilize them. They are developing ceramic membranes with which pure hydrogen can be separated from carbon dioxide and water vapor. 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.
