Quantity and Pressure limitation
This LAP¨refers to the quantity and pressure limitations. It underlines what are the requirements and limitations in terms of pressure and quantity of hydrogen for hydrogen transport. Finally, it shows if it is possible to increase the pressure/quantity, and if yes which authority is competent, what is the process to follow, how long does it takes and what are the costs associated if known.
Glossary:
Quantity and Pressure limitation represent the maximum quantity and/or pressure of gases which is allowed to be transported.
Pan-European Assessment:
There is no limitation in terms of pressure, (mostly transported at around 200-300 bars) In terms of quantity, the limitation is connected to the maximum weight the truck can transport.
Is it a barrier?
Yes

Assessment
National transposition of the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) provides rules for transport of hydrogen by road.
Questions:
Question 1
What are the pressure requirements and limitations accepted for hydrogen transport by road?
The reference rule is the international standard ISO/TS 16111:2006, which defines the requirements applicable to the safe design and use of transportable hydrogen gas storage canisters, including all necessary shut–off valve, pressure–relief devices (PRD), and appurtenances, intended for use with reversible metal hydride hydrogen storage systems. ISO/TS 16111:2006 only applies to refillable storage canisters where hydrogen is the only transferred media. Storage canisters intended to be used as fixed fuel storage on board hydrogen fuelled vehicles are excluded.
Question 2
What are the quantity requirements and limitations accepted for hydrogen transport by road?
No limitations
