Schematic interpretation of key descriptors influencing hydrogen storage performance. High gravimetric density (w) is favored by: (a) light mass (M) and (b) large electronegativity (χ) (strong bond polarity) of host metal atoms. High equilibrium pressure (Peq,RT) at room temperature is promoted by: (c) high molar density (ρmol), low ionic filling factor (ηf), and (d) small χ (weak bond polarity).
