Hurtigruten has made public its updated plans for its Sea Zero project, the zero-emissions ship whose debut is planned for 2030, as it is in the research and development phase.
With the help of large batteries, sails and other innovative solutions, the ship will be able to sail completely emission-free during normal operation, while energy consumption could be reduced by 40 to 50%.
Hurtigruten initially announced its Sea Zero project in October 2022, and then unveiled its first set of renderings in the summer of 2023. As the research and development phase has continued since then, a second set of renderings is now being released, and the plans are further along. Developed in the Norwegian city of Ålesund by Vard, one of Hurtigruten's key partners in the Sea Zero project, it integrates several innovative solutions created in collaboration with partners in the Norwegian maritime industry.
Earlier this year, the cruise line announced its initiative to reduce edible food waste to zero. In addition, the company is undertaking a major €100 million fleet modernization, which includes converting several ships to hybrid battery-powered vessels and incorporating cutting-edge technology that will significantly reduce CO2 and nitrogen oxide (NOx) emissions by 25% and 80%, respectively.
“It is crucial that we take significant steps to reduce emissions. Our goal is to have a zero-emission ship in operation around 2030. We are still in the research and development phase, but we have made significant progress,” said Hedda Felin, CEO of Hurtigruten.
According to calculations, the ship will consume between 40 and 50% less energy than current vessels, allowing it to operate primarily using batteries as its main source of energy.
One of the most interesting features is the sails, which can be raised and lowered as needed. Preliminary estimates indicate that the sails could reduce energy consumption by around 10% over time. In addition, the solar panels will contribute another 2-3% energy savings.
“We continue to see significant energy savings with retractable sails using solar panels, but this requires extensive studies, including prototype testing that will take place in the coming months. We have also changed the sail type to a more mature design already used on cargo ships,” said Hurtigruten Chief Operating Officer Gerry Larsson-Fedde.
Technically advanced:
"The core of the project is reducing energy consumption. The goal is to use significantly less energy than current vessels, which requires innovative solutions," says Larsson-Fedde.
Another measure is air lubrication of the hull, in which air bubbles are pumped beneath the hull to reduce drag. This can result in energy savings of 5-10%. Combined with a modern hull design, advanced antifouling coatings, and regular hull cleaning, water resistance can be significantly reduced. Preliminary results also show that improved ventilation and insulation systems, as well as advanced energy management, can lead to substantial energy savings.
The so-called "smart cabins" will allow guests to control their own energy consumption. Guests will be able to control heating and ventilation via an app and a screen in the cabin, as well as see how much energy is being used. This will increase guests' awareness of sustainability.
"We are already testing advanced sensors in these cabins and, in the near future, we will conduct full-scale tests with passengers on board," Larsson-Fedde concluded.
