Hydrogen and Hydrogen-storage materials

Currently, neutron applications in the field of hydrogen andhydrogen-storagematerials represent a large and promising research area, both fromthe fundamental and the applied points of view. In this chapter we review some relevanttopics from this subject area, including hydrogen bulk properties (concerningboth the solid and the liquid phases), hydrogen storage in nanoporous materials(mainly carbon nanotubes, zeolites, and metal organic frameworks), and hydrogenstorage in solid matrices (particularly ionic hydrides). For each class of materials,the current state of neutron research on their structural and dynamic properties ispresented in detail. Future perspectives in this area are also outlined.
