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
Restrictions (not all road are optimal for certain transport types due risk of terror or road breakdown or traffic jam etc.) to planning routes may increase transport costs – but for the society these restrictions may be optimally chosen.


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 dangerous goods like hydrogen has to follow road selected by the local police and emergency department. Therefore in advance of planning a transport contact the department for the local requirements.
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
Tunnel restrictions: Route possibilities using tunnels depends on design and size of transport container – bulk or bottled. ADR ( EU ref 2) requires tunnels to be classified according to risk. Trucked Compressed gaseous hydrogen can pass class A tunnels at any time. Danish class A tunnels are Limfjordstunnelen and Tårnbytunnelen. The tunnel connecting Copenhagen and Malmø – Øresundstunnelsen is class B and at night time 23.00–06.00. All days the tunnel may be passed by trucks with compressed hydrogen in Cylinders according to the ADR tunnel restrictions for compressed hydrogen. At daytime the Øresundstunnel is classified as class E and therefore no trucked hydrogen can pass the tunnel in day time. –Apart from what is contained as fuel in a hydrogen vehicle
Question 2 Which authorities are competent to allocate the routes? (and at what level: national, local?)
The local police and national–wise: The Danish Transport, Construction and Housing Authority
Question 3 Are the regulations differing from the transport of other types of gas?
Yes to some extend. Passing tunnels depends on the type class according to ADR regulations. Tunnels are classified according to ADR.
