IINS spectroscopy is an important tool for development of understanding of the interactions between the substrate and the adsorbate in hydrogen-storage materials. In addition to carbon nanotubes 17a,b,c), activated carbon 17d), and several other materials are being actively investigated. These include metal organic framework (MOF) compounds 18b,c), zeolites 18d), and metal phosphates 18e). 

Metal organic frameworks are the crystalline materials with the lowest density. As an example, MOF-5 possesses a crystal density of only 0.61 gcm [93]. The volumetric hydrogen storage capacity of MOFs, which is referred to the volume of the material, is therefore affected by these low densities. In spite of this, Muller et al. from BASF recently showed the real potential of MOFs for industrial gas storage applications [81]. They showed that a container filled with MOF-5, IRMOF-8 or a porous Cu-based MOF exceeds, at 77 K, the volumetric hydrogen storage capacity (referred to the whole system) of a pressurized empty container filled with hydrogen.
