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
This LAP is not associated with any barrier in the Norwegian case.


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)
There are no specific requirements for transportation of hydrogen, in terms of roads, specific routes.
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
According to ADR, all tunnels in Europe with special restrictions for transport of dangerous goods shall be marked according to the rules and definitions in the ADR agreement. This also applies in Norway; tank transport of hydrogen is forbidden in tunnels of category B, C, D and E, and hydrogen transport in other containers is not allowed in tunnel category D and E. In practice there is only one tunnel with specified restrictions on transportation of dangerous goods; the subsea tunnel between Ellingsøy and Valderøy, near Ålesund, where tunnel category C applies from 0600 – 2400 every day. Otherwise, there is a special arrangement for a tunnel in Hvaler municipality, where the tunnel is closed every time a transport of dangerous goods is reported. There have also been time–limited restrictions on transportation of dangerous goods in some of the most heavily trafficked tunnels in Oslo. However, the website of the Directorate of Civil Protection (DSB) notes that tunnel restrictions are applied more widely in the EC than in Norway, even if Norway is one of the countries constructing most tunnels in the world, and has more than 1000 tunnels (Institute of Transport Economics, 2012). According to Chapter 2, paragraph 7 of the Regulation of road transportation of dangerous goods, the municipal Fire and Rescue Department has the authority to require that parking/stops for breaks are made in designated areas, in certain cases. However, they cannot impose general rules to this effect. There are no special restrictions for transportation of dangerous goods on bridges. National ferry restrictions are the same as for other class 2 substances: On open, local ferries with foam extinguishers on deck there are no passenger restrictions, but on closed ferries and ferries without foam extinguishers passenger restrictions still apply.
Question 2 Which authorities are competent to allocate the routes? (and at what level: national, local?)
The Norwegian Public Roads Administration [Statens Vegvesen] (national level).
Question 3 Are the regulations differing from the transport of other types of gas?
The rules are the same for hydrogen as for other dangerous substances in CLP ADR class 2, including LNGgoods, including low flashpoint substances. Special restrictions do in some cases apply to explosives.
