Lürssen Launches 114m Fuel-Cell Superyacht Cosmos: A New Era in Sustainable Yachting

Cosmos is Lürssen’s first-ever yacht equipped with a methanol-to-hydrogen fuel-cell system, an innovation that symbolizes the industry’s shift toward cleaner marine propulsion. At its core, onboard methanol is converted into hydrogen via a reformer module, then used in PEM (proton-exchange membrane) fuel cells to generate electricity silently and with zero emissions—producing nothing but water as a byproduct.

This enables Cosmos to operate:

Glass-domed owner’s study perched atop the yacht with a sky terrace—delivering perfect 360° views thanks to custom-engineered curved thick glass

A continuous band of glazing wrapping the cabin deck for panoramic sea views

A bow-mounted observation lounge beneath the helipad, plus an aft balcony with glass balustrade

The yacht’s exterior strikes an explorer-style profile—forward-shifted superstructure, clean sculptural lines, and a rugged, modern aesthetic that signals long-range ambition.

Cosmos is engineered to balance lavish amenities with operational robustness:

Six elegant decks, built with a steel hull and aluminum superstructure

Certified Ice Class 1D, enabling safe cruising through light polar conditions and access to all five oceans and seven continents

The aft main deck is an open leisure haven—with a pool, Jacuzzi, sunloungers, and a dry dock featuring a sledge system for launching the largest tender.

It's a perfect blend of high-capability exploration and indulgent comfort.

Cosmos is more than a superyacht—it’s a deliberate statement of direction. Building her on Lürssen’s 150th anniversary underscores the yard’s commitment to redefining luxury through sustainable innovation.By championing fuel-cell tech in such a high-profile vessel, Lürssen is setting new expectations for environmentally conscious design in large yacht builds. Cosmos may well become the reference point for future builds, where elegance meets eco-responsibility.

Set for final delivery in 2026, Project Cosmos starts a compelling conversation about the balance of opulence and stewardship in yachting. It’s a vision that combines cutting-edge propulsion, contextual design, and bold curiosity—truly a flagship of next‑generation yachting.
