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

Assessment Severity

Assessment

If a higher pressure compared to the current standard pressures of 200-300 bar ise to be used, the vessel has to be certified for this pressure. This is a logical requirement and not a real barrier. It can however be time consuming.

Questions:

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

There is no limitation. Gas cylinders have standard pressures of 200 bar and 300 bar.

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

There is no limitation, as long as the containers are designed for the maximum pressure that can occur during transport.
