Fossilfri kollektivtrafik på vatten

Through literature studies, interviews and active collaboration with an initiated and committed reference group as well as by studying two cases of traffic where fossil- free alternatives have been chosen, this feasibility study has been conducted to assess how a transition to fossil-free public transport on water can be accelerated. The results of the feasibility study can be summarized as follows: 1. With existing budgetary frameworks, it appears possible to carry out a large part of the current public transport on water without today's high greenhouse gas emissions through electrification. 2. There are several obstacles that need to be overcome in order to accelerate the transition from fossil fuels so that set climate targets are also reached for the ferry traffic. 3. All the parties we have been in contact with have emphasized cooperation as a key factor, since the issues that need to be solved are complex and one part alone cannot solve them. Fossil-free public transport on water seems, for the shorter distances, to be best solved by electrification. However, today there are no obvious solutions in place for the longer routes. Also, shorter distance-routes can have challenges such as lack of electrical power at the places where charging is needed or that the operator who owns the quays might not give enough priority to enable charging stations being built. To manage costs while introducing electrification, the total battery capacity installed in the vessels must be limited. This, in turn, will also require that the ferries can be recharged quickly during the part of the day that the ship is in operation. Here, technical solutions are being introduced, but much work remains. Land issues including building permits are considered to be a bigger problem than the charging technology itself.
