This review deals with the main materials employed so far for hydrogen storage and it is specifically focused on the role of surface phenomena in their storage performance. Surface properties are relevant in all classes of materials: when dihydrogen is stored in the form of hydrides, the structure, texture and reactivity of the surfaces have large influence on the kinetics of charge/discharge cycles. In the storage of molecular hydrogen, surface-molecule interactions are responsible for the storage properties of the materials. A better understanding of the fundamental aspects of the chemistry of hydrogen at surfaces is needed in order to design improved storage materials.
