Quantity and Pressure limitation

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?
What are the quantity requirements and limitations accepted for hydrogen transport by road?
Is it a barrier? Yes
Type of Barrier Structural barrier
Assessment Severity
2
Assessment Currently, the high safety factors in regulations ( ADR,TPED) have restricted the increase of payload of hydrogen trailers and restricted the cylinder/tube volume. The availability of low–weight, high volume composite vessels makes it possible to increase the payload which would result in lower delivery costs to the end–users. In order to increase the pressure and/or volume of hydrogen receptacles the relevant standards have to be changed and adopted, the ADR has to be changed as to reference to the new standards, the ADR Directive and TPED have to be amended, the EU Member States have to transpose the ner rules in the national legislation.
