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.

select country:

Is it a barrier?

Yes

Type of Barrier

Structural barrier, Economic barrier

Assessment Severity

Assessment

Maximum allowed pressure of gases is 200–300 bars (which is allowed for transportation; for others technical documentation has to be prepared and approval has to be received – it may be both time and cost consuming

Questions:

Question 1 What are the pressure requirements and limitations accepted for hydrogen transport by road?

Standard transportation pressure for gas bottles – 200–300 bar

Question 2 What are the quantity requirements and limitations accepted for hydrogen transport by road?

No limitations are in place; according to the specifications of the producer of the containers

Describe the comparable technology and its relevance with regard to hydrogen
