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.

What are the pressure requirements and limitations accepted for hydrogen transport by road?
	Today 250 bar is used
What are the quantity requirements and limitations accepted for hydrogen transport by road?
	Only limited by national truck regulations, not specific for gasses.
Is it a barrier?	Yes
Type of Barrier	Structural barrier
Assessment Severity	2
Assessment	Tranpsort safety of high pressure hydrogen has to be proved. No regulation is stopping so the impact should not be overestimated.Since higher pressure than 250 bar have not been used for transportation of gasses, it needs to be shown that this can be done safely, but no explicit regulation forbids it. The costs for transporting hydrogen in this manner is uncertain so far.

	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.
