The listed Norwegian shipping company Havila has banned electric, hybrid and hydrogen cars from its ferries. After a risk analysis, it was concluded that the risk to the safety of the shipping fleet was too great. If a car catches fire, the fire can no longer be extinguished.
The shipping company travels the so-called mail ship route along the coast of northern Norway. The tours are important for Scandinavian passenger and cargo traffic and are also very popular with holidaymakers.
