Hurtigruten has announced an update on its groundbreaking Sea Zero project, a zero-emission vessel slated for debut in 2030, currently in the research and development phase. The ship will employ a combination of large battery systems, advanced sail technology, and other innovative solutions to achieve entirely emission-free operations, while reducing energy consumption by 40-50%.
Originally unveiled in October 2022, the Sea Zero project continues to evolve, with the latest design updates developed in collaboration with Vard, a key partner in the Norwegian maritime industry. The new renderings, released after further R&D, showcase enhanced solutions aimed at pushing the boundaries of sustainable shipping.
Key features of the Sea Zero include battery technology capable of storing up to 60 megawatt-hours of energy, allowing the vessel to operate predominantly on electric power. Contra-rotating propellers will drive the ship, and retractable stern thrusters will assist in port maneuvers and add safety through redundancy. One notable innovation is the OceanWings sail system, which, combined with solar panels, could reduce energy consumption by an estimated 12-13%. The sails, which can be deployed as needed, are expected to provide an approximate 10% reduction in energy use, while solar panels will contribute an additional 2-3%.
Air lubrication technology, where air bubbles are injected beneath the hull to decrease drag, is projected to save 5-10% of energy. This is complemented by modern hull designs, specialized anti-fouling coatings, and regular hull maintenance to minimize water resistance. Improved insulation, ventilation systems, and energy management will also drive efficiency gains.
Hurtigruten's commitment to sustainability is further highlighted by onboard "smart cabins," where guests can monitor and control their energy usage via an app, enhancing environmental awareness.
The Sea Zero project represents one of several sustainability initiatives by Hurtigruten, including the ongoing 100-million-euro fleet upgrade, which is transitioning several vessels to battery-hybrid power. These efforts aim to reduce CO2 emissions by 25% and nitrogen oxides (NOx) by 80%, underscoring Hurtigruten’s leadership in green maritime innovation.
