The gravimetric hydrogen density describes the ratio of the mass of hydrogen to the mass of the material or storage system ... 

The volumetric density of hydrogen in a pressure vessel increases with pressure and reaches a maximum above 1000 bar, depending on the tensile strength of the material. However, the gravimetric hydrogen density of the pressure cylinder... 

Figure 5.53 Volumetric and gravimetric hydrogen density of some selected hydrides. Mg2FeH6 shows the highest known volumetric hydrogen density of 1501 m , which is more than double that of liquid hydrogen. BaReHg has the largest H M ratio of 4.5, that is, 4.5 hydrogen...

High volumetric and gravimetric hydrogen densities due to space and weight limitations, especially in the automobile industry ... 

Elements M formed M(BH4)n, their gravimetric hydrogen densities in the unit of mass% (middle) and the Pauling electronegativity P of M (bottom). Asterisks indicate compounds stabilized at room temperature by co-ordination with ligands. Brackets indicate compounds which have been reported to be unstable at room temperature but may be Isolated at lower temperature. ...
