Hurtigruten has announced an update on its ambitious “Sea Zero” project, which began in 2021. The goal is to have an emission-free post ship operating by 2030, connecting 34 ports between Bergen and Kirkenes. With the project now entering its second phase, the focus is on advanced designs and technologies that will significantly reduce the ship's energy consumption.
A key feature of the new ship design is the use of retractable sails that can be folded when passing under low bridges. These sails are expected to cut energy consumption by around 10%, while integrated solar panels could provide an additional 2-3% savings. "The combination of sails and solar power offers great potential. We expect detailed results from simulations in the coming months," explains Gerry Larsson-Fedde, COO of Hurtigruten.
Another groundbreaking feature is the hull air lubrication system, which pumps air beneath the hull to reduce water resistance, potentially lowering energy use by 5-10%. Further tests of the hull and sail system are planned for early 2025 to fine-tune their performance.
The future ship will be equipped with counter-rotating propellers and batteries with a capacity of approximately 60 megawatt-hours. Two retractable stern thrusters will enhance maneuverability and improve safety during port operations. Additionally, the vessel will benefit from enhanced ventilation and insulation systems, alongside a sophisticated energy management system, all contributing to reducing its overall energy demand.
To offer a more sustainable cabin experience, Hurtigruten is currently testing “Smart Cabins” aboard the MS Trollfjord. These cabins allow guests to monitor and adjust their energy consumption in real time via an app and an in-room display. "Guests will be able to control heating and ventilation based on their preferences, helping them use energy more consciously," says Larsson-Fedde.
With these innovations, Hurtigruten is making significant strides toward its goal of launching an emission-free post ship along Norway’s coast, pushing the boundaries of sustainable shipping even further.
