Road planning

This LAP indicates if hydrogen has to follow specific requirements when transported, and if the regulations are different from the transport of other types of gas. It identifes the competent authorities to allocate the routes.


Road Planning provide the municipalities with a clear understanding of the maximum risks that the transport of hazardous substances may cause. Baseline goals are: Transport hazardous substances between major industrial sites and abroad, including in the future, keeping risks for locals along the routes within legal limits, provide clarity to municipalities about what may / may not be built.

Pan-European Assessment:

Hydrogen is considered as any other flammable gas or dangerous good for its transportation. The Agreement of transport of Dangerous Goods by Road applies.
Is it a barrier?
Assessment Severity
The transport of hydrogen must be in concordance with European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR)


Question 1 Are there any specific regulations or restrictions on the road transport of hydrogen? A) Does hydrogen have to follow specific requirements when transported? (e.g. specific types of roads, specific route)
Transport of hazardous goods follows the national rules transposing the ADR requirements and there are no hydrogen specific regulations.
Question 1 Are there any specific regulations or restrictions on the road transport of hydrogen? B) Please specify the requirements regarding tunnels, bridges, parking, others
a) Tunnels For the road tunnels categorised according to ADR European Agreement as category A, the transport of dangerous goods is allowed without restrictions. The compressed gaseous hydrogen is restricted in principle for category D and when carried in tanks category B. b) Bridges and others According to 1.9.2 and 1.9.3 of the ADR European Agreement the road transport authorities may apply to vehicles for transport of dangerous goods of road certain additional provisions (not included in ADR), provided that those provisions do not conflict with ADR. These could be safety requirements or restrictions concerning vehicles using bridges, ferries or trains, entering or leaving ports or other transport terminals c) Underground parking lots It is prohibited to enter them with tanks, cylinders or other composite vessels.
Question 2 Which authorities are competent to allocate the routes? (and at what level: national, local?)
State Automobile Inspectorate and traffic police
Question 3 Are the regulations differing from the transport of other types of gas?
The regulations for hydrogen transportation follow the ones for flammable gases; when passing through tunnels depend on the ADR classifications and regulations
Describe the comparable technology and its relevance with regard to hydrogen
Transportation of hazardous/dangerous gases (road transport of any other fuels and technical gasses).
