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

Questions:

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

a -No pressure limitation, but pressure depends on the amount and/or packaging (tank or non–tanks shipment) mode of the hydrogen

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

b - No limitations

Annex 2: official Hungarian translation of Annex A and B of ADR
MSDS: material safety data sheet
Section 14: information on shipment
The umbrella legislation is: Directive 2008/68/EK on – inland transport of dangerous goods. The European umbrella legislation must be applied in Hungary directly as it is proclaimed as national Act. Very few supplementary national (Hungarian) legislation exists for this. One such national rule, which makes inland transport of dangerous god (including hydrogen) a bit easier, that only Hungarian language shipping document is necessary for domestic transport.

EU Legislation:

ADR European Agreement concerning the international carriage of dangerous goods by roads.
hazardous materials may in general be transported internationally in wheeled vehicles, provided that conditions be met for the product packaging and labelling; and that the construction, equipment, and use of vehicles for the transport is compliant:
