Giant Lürssen Yacht Operates Exclusively on Electric Power, Capable of Traveling 1,000 Nautical Miles Unassisted
The Luerssen-built megayacht, Cosmos, is turning heads in the maritime world with its groundbreaking methanol-powered fuel-cell propulsion system. This revolutionary technology sets Cosmos apart as an environmentally friendly vessel, offering emission-free cruising for up to 15 nights at anchor or a 1,000 nautical mile range at a cruising speed of 7 knots, all powered by clean energy[1][2].
Key features and technologies of Cosmos include a fuel-cell system that generates hydrogen onboard from methanol, producing electricity without combustion, noise, or harmful emissions. The system uses modular stacks of bipolar plates and membrane electrode assemblies for efficient, low-maintenance electricity generation, with zero exhaust gases and drastically reduced vibrations, enhancing guest comfort and minimising the yacht's environmental footprint[1][2].
Cosmos is also equipped with a hybrid powertrain, featuring MTU 16V4000 diesel engines. This allows the yacht to reach a cruising speed of around 14 knots and a top speed above 20 knots, ensuring a balance between sustainability and performance[5].
At 114 meters and 6,300 gross tons, Cosmos boasts a steel hull and aluminium superstructure, designed by Marc Newson. It features large glass panels, a two-level glass atrium, and a panoramic glass observation lounge, blending luxury aesthetics with advanced engineering[2][4][5].
The yacht's sustainability-focused operational capabilities extend beyond emission-free anchoring and slow-speed cruising. Cosmos has Ice Class 1D certification, enabling safe operation in light ice, allowing exploration of all five oceans and seven continents with reduced environmental impact[3][4].
The owner's support for ongoing research with the methanol fuel cell system installation represents a significant technological advancement towards a zero-emission future within the superyacht sector[4].
The Cosmos offers more than just cutting-edge technology. The adjoining sky terrace is a private alfresco space for the owner, adorned with a swimming pool, a Jacuzzi, and comfortable seating. The observation lounge, encased in glass, provides another scenic vantage point[6][7].
The owner's study, encased in a giant glass dome, offers uninterrupted 360-degree views from the top of the vessel. Luerssen developed a custom solution to bend large sections of thick glass for this unique feature[8]. The cabin deck also features glass, surrounding the entire upper level, and an open balcony with a glass balustrade overlooks the main deck[9][10].
In sum, Cosmos stands out by integrating a first-of-its-kind methanol-to-hydrogen fuel cell power system, enabling long-range emission-free cruising and anchoring, combined with luxury amenities and advanced design features, all supporting environmental responsibility without sacrificing performance or comfort[1][2][4][5].
