in the compressed state Hydrogen is used for road transport
Liquid H2 is used in rockets where the cryogenic complexity is required.
why H2 requires special attention
- Invisible risk
colorless and odorless, hard to notice - Easy leakage
small molecule size increases the permeation and leak probability through joints, seals and fittings. - Ignition hazard
low auto ignition temperature - Buoyant gas
It rises quickly: encoles roof spaces and poor ventilation are critical risk
