Hydrogen and Hydrogen-storage materials

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