Project COSMOS: First superyacht with fuel cell technology launched by Lürssen

By Steph Loseby 9 March 2023

The first yacht to feature fuel cell technology onboard, the 114m (374ft) superyacht Project Cosmos, previously known as Project 13759, has been technically launched from Lürssen’s facility in Rendsburg, Germany. The technology will allow the motor yacht to operate with minimal environmental impact and will reduce its carbon footprint significantly.

At the forefront of innovation, Lürssen has been involved in research projects aimed at using fuel cells on ships since 2009, and since 2012, the development of a modular fuel cell system using methanol has been underway.

The impressive 114m vessel Project COSMOS has not only been designed to become one of the most luxurious yachts in the world, but it is the first to feature this groundbreaking fuel cell technology onboard.

At a Lürssen Live show last year, Peter Lürssen explained: "Fuel cells have very little maintenance and are more efficient than a diesel engine, which is already a very efficient way to produce power." He also mentioned that the fuel cell will allow the owner more than 15 nights emission-free at anchor, or the owner will be able to slow cruise his superyacht for more than 1000 miles emission-free.

How does fuel cell technology work?

Describing the science behind the innovation, Peter Lürssen explained "The core element is a cell which consists of two bipolar plates and one membrane electrode-assembly, in between you build these cells, hundreds of cells are stacked to form a fuel cell stack. Several fuel cell stacks, the FC balance of the plant (compressor, DC/DC, etc.) and the fuel reforming unit, will be combined to a highly integrated fuel cell system. The fuel cell systems, which already meet the specific maritime rules, will be connected with the methanol supply system, the ventilation and electrical infrastructure. Then the magic can start, out comes electrical power and warm, moist air” as by-product."

Superyacht Project COSMOS

Much of the 6,3000 GT yacht’s details have been shrouded in secrecy, including her exterior and interior designers, however, images reveal the vessel appears to have a bold explorer-style profile with the superstructure placed forward to create a large aft deck complete with a swimming pool and a large cut-out, which we can expect to host a large tender.

Crowning her four decks, there appears to be an observation lounge and a helipad on the bridge deck below in true explorer style.

Project COSMOS has been confirmed as the 5th largest project underway for the German shipyard, with seven additional vessels over 100 meters currently in build at Lürssen, including the 125m (410ft) Project Jag that is due for delivery sometime this year and the 116m (380ft) Project Alibaba, due for delivery in 2024.

It is expected that Project COSMOS will be delivered in 2025.

It is not yet known whether the vessel will become a luxury yacht for charter. If you'd like to charter a yacht of a similar caliber, you can view and compare all Lürssen superyachts for charter or get in touch with a recommended yacht charter broker for more information about making a booking.
