Imagine a cruise ship nearly a thousand feet long carrying 1,800 passengers across the ocean with no smoke, no rumbling engines, and no local emissions.
German ship builder Meyer Werft wants to make this vision a reality by building what could become the world’s first fully electric battery-powered cruise ship.
The concept, called “Project Vision,” could dramatically reduce greenhouse gas emissions and potentially change cruising forever.
“Batteries are now in a state with the energy density and other aspects, safety, life cycle and so on, where we say, now this is the most energy efficient way to do cruises,” said Johannes Bade, a project engineer with Meyer Werft.
The proposed ship would plug in and recharge while in port, operating much like the world’s largest electric vehicle, except this one floats.
Meyer Werft said the fully electric design has the potential to reduce greenhouse gas emissions by as much as 95%.
“We do not convert energy to a liquid and then burn it again and use it in electricity again, but to directly use the generated electricity, put it into the batteries during the port stay and then keep sailing on the recharge batteries without any local emissions at all,” Bade explained.
Cruise industry leaders say innovations like this will be critical if the industry hopes to reach its long-term environmental goals.
“It is going to take a mosaic or bundle of solutions to get to net zero for 2050,” said Charles “Bud” Darr of Cruise Lines International Association.
“So every new innovation, I think, is something that we add to that mosaic or toolkit or box of solutions that we’re going to use,” Darr added.
The battery system for Project Vision was developed by Corvus Energy and uses the same technology currently powering hundreds of electric ferries around the world.
Instead of a traditional engine room, the cruise ship would feature a massive battery room, while shore-based charging systems would recharge the vessel while docked in port.
Bade said the concept is ideal for itineraries where ports are relatively close together, including routes in the Mediterranean, Northern Europe, the Norwegian fjords, the Baltic Sea, and even Florida and the Bahamas.
For now, Project Vision remains just that – a vision. But Meyer Werft says the technology is ready and the company could deliver the ship by 2031 if it secures a contract this year.
There are still major infrastructure hurdles ahead.
“Cruise ships call at 1,500 ports worldwide in any given year,” Darr said. “As of today, our data says 41 ports could supply electrical power to one ship. So there’s a whole shore-side element.”
Still, Meyer Werft believes progress is coming quickly, projecting that about 100 European ports could have the infrastructure needed to support battery-powered cruise ships by 2030.
