Electric ferries to come

        The largest connections in Troms are well-suited for electrification, and Enova has given the municipality of Troms municipality an undertaking of almost NOK 81 million for infrastructure to let the ferries offshore.

       Troms county municipality will electrify ferry traffic. At Stornes – Bjørnerå the ferry must be operated with electricity. The same goes for Refsnes-Flesnes, but not Stangnes-Sørrollnes.
The largest connections in Troms are well-suited for electrification, and Enova (national fund for renewables) has given the municipality of Troms municipality an undertaking of almost NOK 81 million for infrastructure to let the ferries offshore.

Mr. Ivar B. Prestbakmo, county council for transport and environment in Troms, states in a press release:

       “We are very pleased with Enova’s commitment. In order to realize good environmental solutions for ferry operations, we are fully dependent on good support schemes. This reduces the additional cost that the county municipality receives by imposing strict environmental requirements. We see from previous Enova allocations that we achieve significant environmental improvements”.

      “New technology can cut large emissions into next-generation ferries. Ferry links are well suited for electrification, and we see that this type of ferry project is also driving forward developments in the maritime sector in general. For Enova, this project is therefore primarily about creating growth in this value chain, says Øyvind Leistad, Marketing and Development Director at Enova.

Electrifies up to four ferry connections

       On behalf of Troms county municipality, DNVGL (Det Norske Veritas with Germanischer Lloyd) has mapped the 6 largest ferry connections in Troms to look at their suitability for electrification. The most important factors are how often ferries go, the ferry size, the length of the connection and the access to power at the quays.

       Mapping showed what it costs to invest in charging infrastructure and what it costs to drive ferry with power compared to continued use of marine diesel. The ties that were mapped were Refsnes-Flesnes, Svensby-Breivikeidet, Lyngseidet-Olderdalen, Stornes-Bjørnerå, Storstein-Nikkeby-Lauksundskaret and Stangnes-Sørrollnes.

       With the means the county municipality has planned to use, it has not been possible in this regard to prioritize the last two links because of high cost.

Big costs

       At most calls, there is insufficient capacity in the mains, and high net or land-based battery costs are expected to ensure that the ferries go close to electricity only.

       “To get more suppliers on the track and build this market further towards the low-emission community, it is important that clear signals from authorities and clients are that electrification is the way to go. Therefore, we are pleased that Troms county municipality agrees to lead their high ambitions, says Leistad in Enova.

       Electrification of these connections results in a reduction of CO emissions, corresponding to approximately 3400 cars, the press release said.

       “I am very pleased with the allocation, which enables Troms county municipality to carry out an exciting and important changeover to electric ferries on any of our ferry routes,” concludes Prestbakmo.

The ferry connections should be lit during the winter 2018/2019.
