Frostabåten

Zero-Emission and Semi-Autonomous High-Speed Mobility in the Trondheim Fjord

Frostabåten is a pioneering initiative to develop and demonstrate a new generation of zero-emission, electric hydrofoil fast-boats supported by semi-autonomous navigation technologies. The project aims to establish a scalable model for future passenger transport in Norway — starting in the Trondheim Fjord and building toward export-ready concepts for international markets.

The project is built around the Swedish-produced Candela P-12, an electric hydrofoil ferry capable of reducing energy consumption by up to 80% by lifting the hull out of the water on underwater wings. This drastically reduces resistance, enabling high speed, low operating costs, and quiet and emission-free operation.

About the project

Project Owner: Frostabåten AS
Project Partners: Ocean Autonomy Cluster, NTNU, FI Ocean Space Incubator, Testination, Candela Technology AB, Trondheim Havn, Crazy Coyote, Frosta Brygge, MIDAS
Financing Partners: Trøndelag County Council, Trondheim Municipality, project partners
Project Status: Ongoing (2024–2027)

Historical Route, New Technology

Frostabåten revives a historic ferry link between Frosta and Trondheim, last operated in 1947. The modern version reimagines the connection as a 25-minute, fully electric and highly energy-efficient crossing, offering a realistic alternative to road travel around the fjord.

Beyond Frosta–Trondheim, the project also explores possible connections to Leksvik, Vanvikan, Munkholmen and Trondheim, creating a regional zero-emission fast-boat network.

Project Objectives

  • Develop and validate a scalable model for electric, zero-emission fast-boat operations.

  • Test and evaluate semi-autonomous navigation and operational support systems.

  • Demonstrate feasibility under Nordic winter conditions (cold, wind, waves, darkness).

  • Produce operational and technical datasets for future tenders, investments and regulations.

  • Build an early-stage ecosystem for commercial routes, tourism services, and regional mobility concepts.

  • Support Norway’s maritime innovation leadership with export-oriented solutions.

Technology and Autonomy Development

The project integrates emerging maritime technologies through close collaboration with NTNU and the Shore Control Lab.

The Candela P-12 used in Frostabåten includes:

  • Semi-autonomous steering and energy optimisation systems

  • Advanced navigation aids that support, but do not replace, the captain

  • Hydrofoil control systems that adjust stability and energy use

  • Data-logging and sensor systems for research and operational analysis

The vessel is not intended to operate without a captain. Instead, autonomy is introduced as assistive technology that enhances safety, efficiency and predictability under demanding conditions.

Technical Specifications – Candela P-12

  • Type: Electric hydrofoil passenger ferry

  • Capacity: 31 passengers

  • Range: Approx. 50 nautical miles (route-dependent)

  • Travel time Frosta–Trondheim: ~25 minutes

  • Energy use: Up to 80% reduction compared to traditional displacement vessels

  • Emissions: Zero local emissions

A hydrofoil is an underwater wing that lifts the vessel out of the water at speed, drastically reducing drag and energy consumption.
