DANFOSS DRIVES FOR DANISH E-FERRY

Jun 24, 2025 | Marine propulsion & machinery news

A newly launched Danish electric ferry, ‘Nerthus’, features Danfoss Drives’ latest iC7 series as a key part of its all-electric propulsion system, which Danfoss says highlights the company’s role in the green transition of maritime transport.

As well as essential components for the ferry’s electric drivetrain, Danfoss provided parts of the shoreside charging infrastructure.

Padmanabhan Kailasam, Danfoss Drives Divisional President, Industrial Drives and Power Conversion, said: “With Nerthus, Danfoss is pushing the boundaries of electrification and sustainability in maritime transport. We want to help build a more competitive, decarbonized future at sea – but this e-ferry is especially meaningful to us because it will be operating on the route between Funen and the island of Als, where Danfoss was founded 92 years ago and where our headquarters campus is still located.”

The new Molslinjen e-ferry uses Danfoss’ iC7-Marine solution, an engineered-to-order system tailored to the demands of marine applications. It runs on 100% electric battery power during normal operation, with a biofuel-powered backup generator for extra flexibility, an upgrade compared to the well-known Ellen ferry, the longest ranging fully e-ferry afloat.

Danfoss’ iC7 solutions are designed to fit the exact needs of each vessel, speeding up delivery and improving efficiency and performance. The system supports hybrid energy storage through the iC7-Hybrid platform, making it a comprehensive solution for modern electric ferries.
