Hydrogen storage using the metal hydrides and complex hydrides is the most convenient method because it is safe, enables high hydrogen capacity and requires optimum operating condition. Metal hydrides and complex hydrides offer high gravimetric capacity that allows storage of large amounts of hydrogen. However, the high operating temperature and low reversibility hindered the practical implementation of the metal hydrides and complex hydrides. An approach of combining two or more hydrides, which is called reactive hydride composite (RHC), was introduced to improve the performance of the metal hydrides and complex hydrides. The RHC system approach has significantly enhanced the hydrogen storage performance of the metal hydrides and complex hydrides by modifying the thermodynamics of the composite system through the metathesis reaction that occurred between the hydrides, hence enhancing the kinetic and reversibility performance of the composite system. Thermodynamic destabilization is achieved when mixing two or more metal hydride/complex hydride that form a new compound during dehydrogenation process. In this talk, an application of X-ray diffraction (XRD) analysis in the RHC system to detect a new compound that form during dehydrogenation process is discussed. The XRD analysis is a simple technique to detect a new compound in the RHC system. The challenges and perspectives of the RHC system are also discussed.
