Electric Fast-Ferry Concept Could Revolutionize Coastal Transportation

Hydro is collaborating in a project in Norway that is developing the world’s first fully electrical passenger ferry, with aluminium playing a central role. The ferry is part of a European Union-funded program, The TrAM Project (Transport Advanced and Modular, to make shipbuilding more efficient, and Hydro is part of the partnership including industry, government and research organizations. Today, ships are built in various custom designs, even though they serve similar functions. By taking a modular approach, like car makers do with common platforms for many models, costs in engineering and production would be slashed.

One ferry, to be built by Fjellstrand AS, near Bergen as part of the TrAM project, is destined for service in the Stavanger region. It will be operated by the Rogaland County Council and Kolumbus, the regional transportation company. Two other ferries may be built for London and Belgium under the EU project.

Shipyard work is slated for 2021-2022, and the ferry is expected to be in operation in 2022-2023.

One ferry can contain 25-30 tonnes of aluminium. For Hydro, the project would include extrusions, panels, friction-stir welding, robotic welding, bending larger panels, optimizing CAD (computer-aided design) services and modular design.

It is also an opportunity for Hydro to lead the development of a new industry standard, as well as using our low-carbon aluminium extrusion ingot and sheet ingot products like Hydro CIRCAL and Hydro REDUXA, which improve the environmental performance even further.

The benefits of an all-aluminium, electrical battery-driven ferry are many. Chief among them is CO2 emissions. Traditional ferries are powered by diesel engines, leading to unwanted pollution, especially when in port. The TrAM ferry has no diesel generator on board, and will charge batteries while in Stavanger port.

Kolumbus operates around 10 vessels on fast-ferry routes. The CO2 emissions from these vessels equal the emissions from all 450 buses that operate Kolumbus’ bus routes in Rogaland, according the TrAM Project, illustrating the importance of zero-emission technology for fast ferries.

Focus on environmental performance was also a driver for aluminium as a building material for the ship. (That Norway uses hydropower for electricity generation makes this solution even better in environmental performance.)

Batteries are heavy, and weight is a challenge when considering speed on water. The need to cut weight is essential, which means using light aluminium in the structure is key to cutting the overall weight significantly. In addition, aluminium is highly corrosion-resistant, making it ideal for marine applications.

Capacity: about 150 passengers, 20 bicycles
Fully electrical battery-driven
Speed: 23 knots service speed
When in operation, will have 11 stops from Stavanger city center
