Electric ferries, batteries and charging

[LoPro]

I just came over this news today and found the charging and battery bit amazing. Maybe others do as well.

The world’s largest electric ferry is set in operation in Norway Monday. Actually 3 of them on the same line. Moving 3.8 million passengers and 1.8 million cars each year.

Each one has a battery of 4300kWh (about 107 Nissan Leafs) and they are charged with 9000kW (!) on each side. Which would have been great if the Tri-motor CT could nip onto for 2 seconds. ?

The world’s largest plug-in hybrid ship, by the way, is in traffic between Norway and Sweden, and has a battery pack of 5 MWh (!) which is enough for electric operation for 60 minutes (in or out the fjord).


I’m sure the battery tech is not especially interesting though as they have no size limitations and cost difference between technologies is probably huge at that level.

And there were problems with the charging initially and the ship had to go by ICE.

Stena Proceeding with Electric Ferry for Gothenburg Decarbonization

Concept design for Stena's all-electric ferry for Gothenburg decarbonization project (Stena Line)

To speed up the transition to fossil-free fuels in the transport sector, Stena Line, Volvo Group, Scania, and the Port of Gothenburg have joined forces to bring about a significant reduction in carbon emissions linked to the largest port in Scandinavia. The aim is to cut emissions by 70 percent by 2030, including a commitment from Stena to proceed with an all-electric ferry.

Named the “Tranzero Initiative,” the initiative includes the electrification of sea transport as one of its goals. The focus is also on the one million truck transports and the 55,000 tons of carbon emissions generated from road transports to and from the Port of Gothenburg each year.

“No single organization or individual holds the key to meeting the challenges ahead of us,” said Elvir Dzanic, Gothenburg Port Authority chief executive. “Collaboration is crucial and we are pleased to bring on board two of the world’s largest truck manufacturers and the world’s largest ferry company. With our collective expertise, breadth, and market presence we can make a real difference.”

The project is commencing with a “needs analysis,” and mapping of freight flows in and around the port to aid with establishing a fossil-free fuel infrastructure. The companies joining the initiative have each committed to introduce a series of interlinked measures designed to accelerate the switch to fossil-free fuels.

As the largest ferry operator, Stena Line will play a key role by introducing new fossil-free vessels into service on the Gothenburg-Frederikshavn route by 2030. Stena had previously discussed the concept of a battery-powered ferry. At the time they said the project still faced hurdles to become profitable. Stena has now committed to proceeding with the vessel.

“We are now transforming Stena Elektra from a vision to a commercially viable vessel,” said Niclas Mårtensson, CEO of Stena Line Group. “Within a year we plan to present the outline specifications and by the latest of 2025, we plan to order the first vessel. This will be a quantum leap in short-sea shipping and a huge step towards fossil-free shipping.”

Stena had previously said that with the rapid increase of capacity and descending prices of batteries, they believed it was only a matter of time until the Stena Elektra would be economically viable. Deputy Technical Manager of Stena Teknik Henrik Nordhammar discussed the concept highlighting that by removing the fuel engines, they also gained the space required for fuel tanks, piping, purifiers, heaters, and exhaust gas systems. However, he noted another challenge would be how to recharge the batteries with 50 MWh of electricity during the 90 minutes in port.

As part of the overall project, the Gothenburg Port Authority will produce the necessary infrastructure and access to fossil-free fuels for heavy vehicles, including electric power, HVO, biogas, and hydrogen gas. Volvo and Scania will put commercial offerings in place for their heavy truck customers, ensuring that in time land transport becomes fossil-free following the goals laid down by the port.

World’s Longest Electric Ferry Now Operational In Norway



By: Andrei Nedelea

It was built in Turkey, but it will serve Norway’s busiest ferry connection.
After successfully kickstarting the electrification of the cars that travel on its roads, Norway has turned its attention to electrifying other forms of transport. And since it is a country with a lot of coastline and many fiords, transport by water is a very popular way to move people and cargo - it has slowly been increasing the number of hybrid or electric ferries.

Recently added to Norway’s electric fleet is the MF Bastø Electric (built in Turkey by the Sefine Shipyard), a fully-electric ferry that can carry either 200 cars or 24 trucks, as well as 600 passengers. It measures 139.2 meters in length, is 21 meters wide and can travel at up to 13 knots (15 mph or 24 km/h). It will serve Norway’s busiest ferry route, some 10.5 km (5.67 nautical miles), between Horten and Moss, across the Oslo Fjord.

The ferry has a battery capacity of 4.3 mWh and it should be able to do between 20 and 24 crossings per day which it will do mostly autonomously, courtesy of a proprietary system by Kongsberg Maritime. Charging will only be done on the Horten side, but plans are to create a facility that allows charging on both ends of the route - peak rate of charge is 9 MW, but it won’t be cranked any higher than 7.2 MW during routine charging.

This is by no means Norway’s first electric ferry, though, just its largest. The first fully-electric ferry to enter active service in Norway was the MF Ampere which debuted in early 2015. With its emphasis on electrifying all forms of transport, Norway will probably become the first country in the world where you will soon be able to travel without any tailpipe emissions - electric aircraft are the final step in this green puzzle, but they are not quite here yet.
