The use of fossil fuels as energy supply is growing increasingly problematic both from the point of view of environmental emissions and energy sustainability. As an alternative to fossil fuels, hydrogen is widely regarded as a key element for a potential energy solution. In this respect, hydrogen storage technologies are considered a key roadblock towards the use of H2 as energy carrier. Among the methods available to store hydrogen, solid-state storage appears to be a very interesting alternative, showing for example the highest volumetric storage densities and high safety. Within the Helmholtz “Advanced Engineering Materials” Programme, the Department of Nanotechnology focusses on the development of both nanostructured hydrogen storage materials and hydrogen storage systems. A detailed account of the actual and future research activities in the field of hydrogen technology at the Helmholtz-Zentrum Geesthacht will be presented.
