2 Conditioning

Hydrogen gas has very low density at ambient temperatures and pressures.

Hydrogen molecules typically undergo some conditioning to make their distribution and use more practical. Common techniques include gas compression and/or liquefaction by reducing its temperature.

Illustration of hydrogen being pressurized


A source of low pressure and low-density gaseous hydrogen can be passed through a compressor to achieve a higher pressure a higher density fluid state.
