In recent years a huge number of novel light weight hydrides has been discovered with many of them showing a rather promising prospect for the use in hydrogen storage.<br/>Results attained by different characterisation techniques as in-situ XRD, small angle X-ray scattering, EXAFS and XANES, volumetric Sieverts’ type measurements, in-situ neutron radiography etc. on different hydrides and hydride composites will be presented. Insights about reaction mechanisms, sorption behaviour, cycling stability of light weight hydrides and Reactive Hydride Composites, the influence and optimisation of compaction on such materials to pellets and the behaviour of such pellets under in-situ conditions are given.<br/>The possibility for scale-up of the synthesis as well as the kinetic and cycle behavior of larger sample batches considering for example the effect of temperature inhomogeneities on the performance and cycle life time of the storage materials has been studied. An overview about methods and achieved results on the scale-up of synthesis and testing of different hydrides will be given.<br/>Advantages and limitations of their possible usage for hydrogen storage applications will be discussed.
