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

The procedures that is necessary to be used and that are available to all dangerous goods, not only hydrogen.Maximum pressure of gases which is allowed to be transported is limited at 200 bars, for pressures above there is necessary to prepare a technical documentation and on this base the user receive an approval, that attract supplementary costs and time–consuming.

Questions:

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

Yes, 200 Bars. ISCIR – National Authority for Control and Approval of Boilers Pressure Vessels and Hoisting Equipment, http://www.iscir.ro can approve other maximum pressure on the base of the technical documentation/report.

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

There are not any limitations.

Describe the comparable technology and its relevance with regard to hydrogen

Road transport of any other technical gas
