Jülich, 30 November 2016 – The combustion of fossil energy carriers in coal and gas power plants produces waste gases that are harmful to the environment. Jülich 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 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.
