Adventure cruise company Hurtigruten Norway today revealed plans for a zero-emissions electric cruise ship with retractable sails covered in solar panels, which is due to set sail in 2030.
The company currently has a fleet of eight ships, each with a capacity of 500 passengers, that travel along the Norwegian coast from Oslo to the Arctic Circle. Although a relatively small firm, CEO Hedda Felin hopes that this innovation “can inspire the entire maritime industry.”
The project, named “Sea Zero,” was initially announced in March 2022 and since then, Hurtigruten Norway, along with 12 maritime partners and Norway-based research institute SINTEF, has been exploring technological solutions that could help to achieve emission-free marine travel.
The zero-emissions ship's sails will retract so that the ship can pass under bridges, as shown here in a rendering.
The resulting design will run predominantly off 60 megawatt batteries that can be charged in port with clean energy, as renewables account for 98% of Norway’s electricity system. Gerry Larsson-Fedde, SVP of marine operations for Hurtigruten Norway, who came up with the idea of a zero-emission ship, estimates that the batteries will have a range of 300 to 350 nautical miles, meaning that during an 11-day round trip, one liner would have to charge around seven or eight times.

Heh, from a carrier that I served on, I thought much the same thing.
I recall seeing a Knox class frigate in the North Atlantic, and thought “How the hell do they eat and sleep on that thing, slewing, pitching, and yawing through the ocean as it is?”
Those on the FF pondered the same thing.
A ship with rolling blackouts from cabin to cabin
LOL, my brother, who served on a destroyer told me they just dealt with it as a fact of life!
When it is really bad like that on a DD or FF no one sleeps very much or eats all that ( PB sandwiches ) much. Or showers all that much. Just go on watch and hang on ‘till the next watch and hope you don’t get sick.
I think the dead giveaway was the straps with buckles on the racks!
The worse part is the shuddering that happens when the sonar dome pops out then crashes back down. Shuddering will make even the hardiest feel awful.
The only good thing is if you time it just right then you can climb a ladder in one step!!
Such an American vessel is no longer possible because they are labor intensive. The cost of Union Labor would be prohibitive.
I don’t see any lifeboats in that picture. Where will they be stowed, or is this ship unsinkable?
Funny. I was on carriers, and the worst we had even in the highest ocean was walking into a bulkhead...and gently, at that...:)
Just curious, what class did you serve on?
When I was up that way near the arctic circle in November 1976, I tell people the story about the time we were in a particularly strong gale, and they didn’t let anyone go on deck except the men tasked with ensuring the tiedown chains on the planes (usually 24 of them in weather like that) were secure and tight.
Me and two other guys decided to venture out in the catwalk that ran the perimeter of the deck near our shop, and we were in a spot that they couldn’t see us from the island due to the shape of the deck (we were just forward of the deck angle on the starboard side)
Well, we opened the hatch and crept out into the catwalk to survey the scene.
About 90 feet below our feet looking through the grating was the ocean.
It was a bright, sunny day, and all around us, the ocean, usually a dark blue bordering on black, was an odd color of green. There was white froth everywhere being streaked across water, and water was being swept away into the wind at the tops of the huge waves.
It was very impressive.
Several hundred yards off our starboard beam was a Knox class frigate, and we stared open-mouthed at it. (at least I was open-mouthed!)
As she plowed forward, her bow would bury into that frothy green water, and a wave would travel up the deck until it hit the superstructure, when the bow would rise up, come completely clear of the water, and then plunge down again.
As the bow plunged into the water, the stern came out of the water, and you could see the single screw turning like mad.
All the while the frigate was pitching up and down, the ship was rolling from side to side, and also yawing back and forth.
It seemed to be moving in every single possible direction. That was the first time I had seen a vessel of that size behaving that way, and that was when the thought entered my mind “How in the hell do they eat, sleep, or even function on that thing?”
Then, we crept a little forward, nut-to-butt (keeping our heads down so as to avoid being seen) so we could see the bow wave of our ship.
To our astonishment, the entire bow came out of the water, tons of water cascading back into the ocean as the carrier’s bow very slowly rose, and as it reached the maximum height, seemed to pause in the air. Then, ponderously, it began to fall back to the ocean, picking up speed, and when it hit the water, the impact sent huge waves running off in every direction. Years later, I saw a photo that brought it to mind...a man, looking out the door of a lighthouse in the North Sea somewhere, and a giant wave splashed all around him. When I saw that picture, it immediately reminded me of the bow of that carrier hitting the water as it came back down.
Then, after it hit the water, it kept going into the water, and didn’t seem like it was going to stop, and I felt the water we could see through the catwalk was rushing up at me and would sweep me away.
I wasn’t the only one of us who had that moment of panic, because as I instictively turned to scramble back through the hatch, I collided with the backs of my two shipmates who were clambering in a panic to get back inside as well!
Of course, we weren’t in any danger of that, but...it was so massive a show of hydraulic power that none of us really knew WHAT was going to happen, but...WE didn’t know that!
