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.

Much more accurate
Part of the USN shipboard 12 o'clock reports (from the officer of the deck to the captain, via the messenger of the watch) was "the magazine temperatures are normal".
Wonder how much power is required to provide heat aboard the ship when they’re at the arctic circle end of the cruise.
The QE2 (retired from service) has total generation capacity of 95 MW.
The more modern Queen Mary 2 has a total on-board generation capacity of around 120 MW (megawatts).
It takes around ten acres of land space to generate one megawatt of electricity on land. An acre is 43560 square feet.
The best currently-available photovoltaic cells generate about 20 watts per square foot under optimal conditions. That’s 50000 square feet per megawatt, if you could get 100% area coverage. Of course, you don’t often have “optimal conditions” anywhere, including at sea. Figure you have to quadruple that figure to be realistic as an average. That’s more than four acres of 100% PV cell area per megawatt. Now multiply that by about 75 to get a realistic figure for a large cruise ship. We’re talking close to 400 acres; a square mile is 640 acres.
That’s all assuming 100% coverage, which you won’t get. Land-based PV generation is lucky to get one third of that. So you’ve got to at least double that 400 acre estimate to account for the space between solar panels.
Now compare that area to the area of the deck of a cruise ship.
Another floating apartment building full of obnoxious tourist...What a great getaway...☺
there would be 4000 less idiots.
Hurtigurten ships only carry about 500 people. They are small cruise ships. Very, very, very expensive arctic and Antarctic cruises.
In the Arctic summer with an 18 to 20 day this sort of makes sense.
Nice allusion - it’s going to take a Clinton-era Freeper to truly appreciate that one!
Almost nothing illustrates the disingenuousness of the Greenies more that their attitude towards hydro. When they’re trying to make the strained case that as ‘renewables’, solar and wind are actually practical, they’ll always include hydro as ‘renewable’, since in most locations, hydro provides more energy (and does so reliably) than windmills and solar panels. Meanwhile, they’ll do everything possible to keep new dams from being built, while also doing what they can to tear down old ones.
“I have no doubt that somewhere, government subsidies are in the cards...”
At least they are Norwegian subsidies...I hope! It wouldn’t surprise me one bit for the US to subsidize it.
Thank you for your service, shipmate! What kinds of vessels did you serve on, just curious?
Exactly right. The leftist illogical beliefs are astonishing. They are perfectly happy holding two opposing points of view at the same time.
Dams Bad — no good because reservoirs silt up, stop fish spawning, and they ruin vistas. But they have zero concern for millions of windmills despoiling our country’s magnificent vistas. Dams are hidden away in remote locations where you can only spot them on an airplane flight. Windmills are everywhere and close to cities and towns.
Dams Good — “renewable” energy when they want to take credit for it. But don’t build any new ones and, better yet, tear down old ones.
Thanks! Did a "Kiddie Cruise"; enlisted at 17, due to be discharged the day before my 21st birthday. Assigned to the USS Vulcan (AR-5), a repair ship, out of boot camp. She was a floating machine shop with four 5 inch guns to make her a warship. Deck Seaman; trained as helmsman, lookout, phone talker (bridge-shipwide communication), security watch, messenger, NBC decontamination. My battle station was first loader on #2 gun mount.
When I reported aboard, I was told by shipmates that she was welded to the pier and mired in her own coffee grounds. Imagine my surprise when a couple of months later we got the order "make preparations for getting underway". We got underway and moved...a couple of miles up the bay to the Army Piers.
Our "war" was the Cuban Missile Crisis. We were tasked with evacuating military dependents and civvy contractors from GTMO.
Ah! Wasn’t she a destroyer tender?
Now I have to look…
My mistake… She sounded like an all-around repair ship for everything. While it sounded like she wasn’t doing a lot of real steaming later in her career, there must’ve been some pretty interesting repair jobs that took place with her crew.
My dad was on one of the destroyers, down in the Cuban missile crisis (the USS, Bristol, DD 857) as well.
I would bet a sailor would learn a lot of things on a ship like that.
You know, I was fumbling around in my brain for something to connect that name to, and when I read your post, I realized that was exactly what my brain was circling around, but couldn’t get to it!
i love it.
Bruce Willis and Milla Jovavich... what a blast!!
Vulcan was built in 1940, I think. She served in the Pacific and there were stories about her getting damaged carriers back into the fight after a couple of the battles.
We had it pretty nice in comparison with the WWII Tin Can sailors, and your dad and his shipmates as well. Tight quarters on those cans!
