Hydrogen is a promising energy carrier for the future, especially for mobile applications. It can be stored safely and reversibly at high volumetric densities in hydrogen storage tanks filled with light metal hydrides. Due to the high sensitivity of neutrons towards hydrogen, Neutron Radiography (NR) is the ideal technique for in situ investigations in order to directly observe the hydrogenation behaviour of the metal hydride material inside the tank under operating conditions. Already qualitative investigations revealed interesting macroscopic structure changes for the hydorgen absorption [1,2]. In a further step, the full spectrum of available neutron energies at different imaging beamlines was used for a comprehensive quantitative study of scaled up metal hydride materials, including in operando studies as well as tomography studies. The results help for the optimization of metal hydride based hydrogen storage.
