Les saken på norsk – A breakthrough for emission-free and autonomous mobility at sea. This week, an electric hydrofoil from Swedish Candela was tested and trial-sailed in Trondheim Fjord as part of the Frostabåten project. The tests represent an important step toward new emission-free commuter routes, and eventually more autonomous solutions for passenger transport at sea. The project is led by Linda Hald, project manager for Frostabåten, through FI Ocean Space Incubator. Its goal is to explore how electric hydrofoils can be integrated into future public transport offerings, both for commuters, tourism, and new mobility concepts.

The trips served both as technology tests and as data collection opportunities in collaboration with research environments. – We have brought together the entire ecosystem around the project. Public actors, industry, research institutions, and technology suppliers have all been involved. Now we have shown that this can be realized in practice, says Hald. At 15 knots speed, the foils lift the hull out of the water and the boat flies.

NTNU developed a dedicated Gateway, a compact and user-friendly box that connects to power, cameras, and antennas. The solution collects and sends high-quality audio and video streams directly to the control room. Ole Andreas Alsos, head of NTNU Shore Control Lab.

This demonstrates how quickly this type of solution can be implemented, says Alsos. – The next step is to demonstrate remote control of Frostabåten from the control room, explains Alsos. NTNU had planned four hours to set up the equipment onboard. They finished in just 30 minutes. Photo: Lars Bugge Aarset/Fremtidens Industri. Technology providing speed and efficiency Frostabåten is an electric hydrofoil developed and produced by Candela. It is lifted out of the water by computer-controlled hydrofoils, which reduce friction and energy consumption, provide stability and comfort, and extend battery range compared to traditional boats. Propulsion is provided by Candela C‑Pod motors with counter-rotating propellers, offering quiet, efficient, and maintenance-free operation. The combination of computer-controlled hydrofoils and direct electric propulsion makes the vessel highly energy-efficient and comfortable to sail. – The most important thing now is to show that this works in practice. The technology is mature, and the vessel has already been in commercial operation in Stockholm’s public transport for over a year. Now it’s about engaging people and decision-makers to show that this is a realistic solution in Trondheim Fjord as well, says Alexander Sifvert, director for leisure sales at Candela.

NTNU, with Shore Control Lab, is a key partner for testing and research on remote monitoring and autonomous systems. Trondheim municipality and Trøndelag County are important public partners and contribute funding to the project. Mayor Kent Ranum attended the tests.

Trøndelag County has indicated plans to support the purchase of electric vessels and the development of new routes, including through the Klimasats program. – This is not just about one boat, but about developing a new mobility concept. Bus at sea, taxi at sea, and new connections that both reduce emissions and make better use of sea areas, says Hald. In January, a new and more extensive test period is planned with additional trips, public demonstrations, and further technology testing. Munkholmen could be one of Frostabåten’s stops.

Here, mobility, maritime technology, research, and regional development come together in a concrete test and development project with significant scaling potential, says Hald.
