Formation of hydrides (IMAGE) National Institute for Materials Science, Japan Caption Figure. (a) Grouping of chemical element on the periodic table that form different types of hydrides. (b) Bulk moduli and hydrogen absorption capacities of various transition metals and representative intermetallic compounds. Materials evaluated may be divided into those with hydrogen storage capability (blue) and those without (black).
