Zero-emission transatlantic passenger travel starts here
Introducing ÆQUORIS - a bold new concept for clean ocean travel.
Powered entirely by cryogenic liquid hydrogen, ÆQUORIS is designed to cross the Atlantic in comfort and safety, with zero emissions. No fumes. No CO₂. The only thing she leaves behind is pure, clean water.
ÆQUORIS may be a concept, but this is a fully realised design, with a complete general arrangement, innovative technical solutions, and beautiful, sustainable interiors.
How ÆQUORIS makes it possible
We consulted with leading industry experts, suppliers, systems engineers and researchers in the field of marine decarbonisation to develop a robust, realistic and achievable power system, using commercially available solutions.
All of this combines to give ÆQUORIS an unprecedented target range of 4000 miles.

Twin 7.5 MW propulsion pods
2 x 1.5 MW bow thrusters
Watch this space…
ÆQUORIS was peer reviewed at a round table event hosted by IMarEST during London International Shipping Week 2025. Representatives from class, academia, LH₂ infrastructure, and cruise operators were all present, and provided fantastic levels of support and input. We came away with a wealth of ideas, contacts and enthusiasm.
As of Q4 2026, ÆQUORIS is in further development with our partners at 426 Maritime. We’ll be announcing project updates, techincal improvements and next steps in the coming months!
