Danfoss Editron has supplied the hybrid electric drivetrain system for a new ferry, which entered operations to transport people between Thyborøn and Agger in north-west Denmark.
Delivered by the country’s Søby Værft shipyard, the new 45.9m-long ferry will transport 140,000 passengers a year. It will replace an existing ferry that has been operating for the last 40 years.
The Editron system includes two 374kW electric propulsion motors, two 323kW diesel engines, two electric generators mounted onto the diesel engines, and two 75kVA hotel load outlets for alternate current consumers.
To store the energy, the system is fitted with two 78kWh battery packs, a 45kVA shore charging connection, and two compact direct current panels with power management system controllers.
The system has been designed to function in harsh conditions, including the rough waters of the North Sea in which the Thyborøn-Agger ferry operates.
Thyborøn-Agger ferry crossing leader Kim Raabjerg Korshøj said: “Danfoss Editron’s system was smaller and lighter than other products by a weight equal to four cars, meaning it was the perfect choice to be used in our new hybrid-electric ferry.
“The space savings and high efficiencies mean that, even though the new ferry is larger than the old one, it is expected to have a lower operational cost per crossing due to the savings in fuel and the reduced maintenance needs.”
The hybrid electric drivetrains will also help cut emissions, maintenance and fuel costs.
With a capacity to carry 22 vehicles, the new Thyborøn-Agger ferry can also transport 5,000 trucks and 50,000 passenger vehicles annually.
Owned by the municipality of Lemvig and Thisted, the ferry will enable the Danish government to meet its EU 2020 climate and energy goals.
