The designers of the world’s first hydrogen-fueled super yacht have denied the $645million vessel is going to Microsoft boss Bill Gates.
The 370ft vessel, which only emits water, had been linked to Gates for his penchant for super yachts and his keen interest in technological solutions to climate change.
But Sinot, the designers of the concept ship, have since denied this is the case.
The yacht, unveiled at the Monaco Yacht Show last year, comprises five decks complete with space for 14 guests, 31 crew members, a gym, yoga studio, beauty room, massage parlor and cascading pool on its rear deck.
But its most impressive feature is locked away in the hold – two 28-ton vacuum-sealed tanks that are cooled to -423F (-253C) and filled with liquid hydrogen which powers the ship.
The Aqua superyacht is a futuristic design that is 370ft-long, comprised of five decks, and runs off liquid hydrogen meaning it only emits water. Design studio Sinot said the exterior of the vessel was inspired by ocean swells, the movement of the tides, and weather out on the open ocean
The rear of the vessel has two entertaining areas – one lower lounge area for sunbathing or swimming – and an upper entertaining space with room for outdoor dining. Gel-fuelled fire bowls allow guests to stay warm on colder evenings without having to burn wood or coals
The rear deck features an infinity pool which cascades towards the ocean, while floor-to-ceiling glass windows lead through into a downstairs entertaining space with dining room for 14 people and a home cinema
Aqua was unveiled at the Monaco Yacht Show, which runs from September 25-28 in Port Hercules. While the yacht is only a design concept at the moment, its architects hope it will inspire future designs based on its eco-friendly fuel system
A huge staircase at the centre of the vessel spirals around a water feature (centre) to the lower level, where the ship’s hydrogen fuel tanks can be viewed through a glass panel (rear). Each tank weighs 28 tons, is vacuum sealed and cooled to -423F (-253C) in order to hold the hydrogen fuel
The liquid hydrogen is pumped through special PEM fuel cells which convert it into electricity which runs the engines and electronics on board. The supply is moderated using two fuel cells to make sure it stays constant. The only emission from the system is water, which can be safely pumped into the ocean
The new vessel is not expected to be ready to take to the open seas until 2024.
In a statement, Sinot said today that claims the vessel’s concept had been bought by Gates were ‘factually incorrect.’
The hydrogen is pumped through a special type of fuel cell which converts it into electricity, while emitting only water which can be safety pumped into the ocean.
Despite its novel fuel source, the vessel is able to reach 17 knots and travel 3,750 miles before it needs to refuel, enough to cover an Atlantic crossing from New York to Southampton.
Designer Sander Sinot is hoping it will pave the way towards a more ecological future for the superyacht industry.
The boat will easily be able to cross the Atlantic but it will also have a backup diesel engine due to the scarcity of Hydrogen refueling points
The ship’s wheelhouse is located under a bubble hood-shaped roof on the bridge deck and has a 360 degree view of the surrounding ocean. It is from this spaceship-like room that the ship’s captain and his 32-strong crew operate the vessel
The master suite occupies the entire 50ft width of the Aqua under a central skylight, broken into separate ‘rooms’ using wooden dividers. Floor-to-ceiling windows provide plenty of light from both sides, while the interior can be decorated however the new owner wishes. A doorway at the read leads through to the bedroom and bathroom
The yacht contains enough space for 14 guests and 32 crew, including the huge owner’s pavilion (bedroom, pictured), two other VIP state rooms for their most valued guests and four regular state rooms
The master bathroom also features floor-to-ceiling windows looking out over the ocean, a large central bathtub, his-and-hers vanity units off to either side, and his-and-hers shower units to the left and right
Gates, 64, is known to regularly take vacations onboard superyachts and would usually rent boats during summer trips to the Mediterranean. Here he is pictured along with Melinda in Turkey in 2005

He said: ‘With every project, I challenge my team and myself to surpass ourselves. For development of AQUA we took inspiration from the lifestyle of a discerning, forward-looking owner, the fluid versatility of water and cutting-edge technology to combine this in a superyacht with truly innovative features.’
Working alongside Lateral Naval Architects, Sinot spent five months perfecting the details in the yacht in the hopes of one day being able to transform it into a real vessel.
Although this new yacht will be run on liquid hydrogen, there will also be an engine that runs on diesel as a back-up due to a current lack of hydrogen refueling stations.
The gym features a range of workout machines, a full set of dumbbells and a yoga studio. A window stretching the entire width of the gym at sea-level gives the impression of working out on the water itself
Located in a room to the side of the gym is the hydro massage room, where passengers are massage by soothing water jets that rain down on the central granite table
The upper-deck lounge area leads directly off the owner’s pavilion area and has floor-to-ceiling windows as well as views out over the outdoor entertaining space. It can be used either as a casual entertaining space, or for al-fresco dining
A lounge space within the lower-deck entertaining area can either be set up for casual conversation, or rotate to face a cinema screen. Behind the seating area is the formal dining space, with settings for 14 people
Aside from the fuel source, the yacht’s other features include a wheelhouse that looks like something out of a spaceship, a huge central staircase spiraling around a water feature, and a beauty and fitness suite.
The rear deck features two entertaining areas – one upper and one lower – along with a cascading pool, sun loungers, and outdoor dining space.
There is also storage space for two 32ft tenders – smaller boats used to get to and from the main yacht – three jet-skis and smaller ‘water toys’.
Computer-generated images of the yacht, along with a 10ft scale model, were unveiled by Sinot at the Monaco Yacht Show last year.
The yacht’s designers said they wanted it to combine ‘ground-breaking technology with cutting-edge design’ and provide a blueprint for future designs using eco-friendly fuel sources
This water feature – comprised of a jet falling from the ceiling into the pool below – sits at the centre of the gym complex, with doorways at either side leading to the workout room and the massage parlour

HOW DO HYDROGEN FUEL CELLS WORK?
Hydrogen fuel cells create electricity to power a battery and motor by mixing hydrogen and oxygen in specially treated plates, which are combined to form the fuel cell stack.
Fuel cell stacks and batteries have allowed engineers to significantly shrink these components to even fit neatly inside a family car, although they are also commonly used to fuel buses and other larger vehicles.
Oxygen is collected from the air through intakes, usually in the grille, and hydrogen is stored in aluminium-lined fuel tanks, which automatically seal in an accident to prevent leaks.
These ingredients are fused, releasing usable electricity and water as byproducts and making the technology one of the quietest and most environmentally friendly available.
Reducing the amount of platinum used in the stack has made fuel cells less expensive, but the use of the rare metal has restricted the spread of their use.
Recent research has suggested hydrogen fuel cell cars could one day challenge electric cars in the race for pollution-free roads, however – but only if more stations are built to fuel them.
Fuel cell cars can be refueled as quickly as gasoline-powered cars and can also travel further between fill-ups.
Fuelling stations cost up to $2 million to build, so companies have been reluctant to build them unless more fuel cell cars are on the road.
The U.S. Department of Energy lists just 34 public hydrogen fuelling stations in the country; all but three are in California.
According to Information Trends, there were 6,475 FCV’s worldwide at the end of 2017.
More than half were registered in California, which puts the U.S. (53 per cent) at the forefront for FCV adoption.
Japan takes second place with 38 per cent, while Europe is at nine per cent.
