Volumetric hydrogen density (gH/L) of a variety of hydrogen storage methods including compressed gas (350 and 700 bar), physisorption in a metal organic framework (MOF), liquid hydrogen (LH2), ammonia (NH3), methane (CH4), and a variety of metal and complex hydrides. The values present in this graph are only for the storage medium and do not take into account the full system volume (e.g., tank and fuel cell).
