Sinot Presents Hydrogen Powered Yacht

Sinot Yacht Architecture & Design has presented project Aqua, a 112-metre superyacht. Designer Sander Sinot: ‘Our challenge was to implement fully operational liquid hydrogen and fuel cells in a true superyacht that is not only groundbreaking in technology, but also in design and esthetics.’

The yacht was designed in collaboration with Lateral Naval Architects. The hull and energy and space efficiency were optimised to allow for a speed of seventeen knots and a range of 3750 nautical miles.

‘We consider Aqua to be a major step forward in the application of new technologies aboard a superyacht,’ says Sinot. ‘We focused on an environmentally sensitive subject: yacht propulsion and the choice of fuel. To take this discussion into an entirely new realm we have initiated Aqua, our new yacht concept, using a hydrogen-electric system capable of catering for all onboard energy needs.’

Hydrogen

The Aqua is fuelled by hydrogen. The system is based on the use of liquified hydrogen, stored at -253°C in two 28-tonne vacuum isolated tanks. The liquified hydrogen is converted into electrical energy by proton exchange membrane (PEM) fuel cells, with water being the only by-product. All parameters in terms of output, system layout, range and physical dimensions were translated to a complete hydrogen/electric based system.

The generated electrical energy is transmitted to Aqua’s switchboards, where it is distributed to provide power for propulsion, auxiliary systems and hotel services. Large batteries buffer the generated electricity to ensure power demands are always met.

Exterior Design

The flowing exterior lines of Aqua are inspired by ocean swells. The curved top deck culminates in a bow with integrated front bow observatory, the Aqua room. The hull is a sculpted overall double curved volume, intersected by glass band windows, which subdivide approaching the aft stepping down to the water.

The raised front profile provides ample space for accommodation and technical facilities. The yacht is configured with a five-deck set up, utilising forward interior space through the high sheer line which subtly descends from bow to aft.

The yacht has been designed to provide those on board with the closest possible proximity to the water. The aft deck features an innovative series of platforms cascading down towards the sea, while a large swim platform allows all passengers to access the water at sea level.
