Lürssen has officially launched the 114.2-metre Project Cosmos from its Rendsburg shipyard in Germany — a groundbreaking vessel that marks the yard’s first-ever superyacht to feature fuel-cell technology.
Also known as Project 13759, the yacht represents a major step forward in sustainable yachting. “Fuel cells have very little maintenance and are more efficient than a diesel engine, which is already a very efficient way to produce power,” commented Peter Lürssen when the innovation was first revealed in 2021.
Design & Exterior
Styled inside and out by world-renowned designer Marc Newson, Project Cosmos boasts a sleek, futuristic profile with elegant flowing lines. A distinctive rounded glass observation pod at the bow, sweeping black glazing, and a vast uncluttered foredeck set her apart. The foredeck accommodates a helipad, while the expansive aft deck features a swimming pool and a cut-out section that appears to house a large tender or additional watercraft.
Constructed with a steel hull and superstructure, the yacht measures 18 metres across the beam and offers an estimated 6,300 GT of interior volume.
Sustainability & Innovation
At the heart of Project Cosmos lies a methanol-powered fuel cell propulsion system. This advanced technology enables the yacht to operate with zero emissions at anchor for up to 15 days or to cruise slowly for approximately 1,000 nautical miles. The system uses stacks of fuel cells formed from bipolar plates and membrane electrode assemblies, all integrated into a maritime-compliant methanol supply, ventilation, and electrical network.
A Pioneering Milestone
First glimpsed out of the shed in March 2023, Project Cosmos has since undergone extensive outfitting in Kiel and Rendsburg. Now launched, she stands as a milestone in large yacht design, combining cutting-edge green propulsion with the luxury and craftsmanship for which Lürssen is renowned.
