Inside the Radical New Hydrogen-Powered Yacht Concept That Could Change the Marine Industry As We Know It

'Aqua' pushes the envelope in every possible way.
BY RACHEL CORMACK ON SEPTEMBER 20, 2019

Aqua may not the most inventive name for a boat, but Dutch design studio Sinot’s newest yacht concept more than makes up for its humdrum moniker with a radical dose of innovation and future-forward design.

Developed over the past five months—and unveiled just days before the Monaco Yacht Show—the behemoth 360-foot-plus superyacht prototype marks an exciting step forward in the marine industry: Aqua will be fully powered by liquid hydrogen. The handiwork of Lateral Naval Architects, the hydrogen propulsion system promises smooth and silent sailing at longer range with zero emissions—a major selling point for eco-conscious seafarers.

So, how does it actually work? The liquified hydrogen—which will be stored at -253°C in two 28-ton vacuum isolated tanks—is converted into electrical energy by proton exchange membrane fuel cells (PEM) and used to provide power for propulsion, as well as the auxiliary system and hotel services. Batteries buffer the generated electricity to ensure power demands are always met. The result is a near noise-free sustainable sailer that boasts a top speed of 17 knots, a cruising speed of 10 to 12 knots and a range of 3750 nautical miles.



“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 aesthetics,” designer Sander Sinot said.

Indeed, Aqua pushes the envelope when it comes to aesthetics, too. The exterior—inspired by “ocean swell”—sees curved lines flow across a five-deck set-up which has been designed to get guests as close as possible to the water: The aft deck features a water-covered staircase that cascades down the deck towards the ocean, while a generous-sized pool blends into the surrounding sea.... more: https://robbreport.com/motors/marine/inside-the-radical-new-hydrogen-powered-yacht-concept-that-could-change-the-marine-industry-as-we-know-it-2870615/

1. If it could take hydrogen directly from the water, I would be impressed. BUT...

It takes 56 tons of liquid hydrogen to run this thing?

Sorry. I won't be going on board.

Ever been in a house that is heated by propane?



People scared of H2 are hilarious.

Hydrogen is safer than propane.

What happens when you see a propane truck?

7. Sources and/or proof?

------------"unlike Hydrogen"--------

Hydrogen is a multi-billion dollar industry RIGHT NOW

Around 70 million tonnes of hydrogen are used today SOURCE

How many hydrogen explosions have you heard of?

"Propane has a safe track record"

Sure it does!




As I said - Hydrogen is safer than propane

Can you guess why?

4. "People scared of H2 are hilarious. Hydrogen is safer than propane."

Hardly.

Propane boils at -43f
Hydrogen boils at -432f

Do you know what that means?

I've worked with liquid oxygen tanks and that's scary enough. At least you can vent overpressure into the air without worrying about blowing up...unlike hydrogen.

If that ships got a normal, Insulated tank, then lame...given any sufficient length of time and you'll either have two highly pressurized bombs on board, or will have vented your tanks dry.

If it's cryogenically kept, using some sort of refrigerant, then your better hope you don't lose power for any real length of time or again, 2 bombs or empty fuel tanks.
Power losses happen on boats fairly regularly.

8. hydrogen is safer than propane

because escaped H2 flies into space at 45 MPH

escaped propane sinks, collects and waits for a spark

Toyota shoots a tank full of H2 at 700 bar



-----------------"If it's cryogenically kept, using some sort of refrigerant, then your better hope you don't lose power for any real length of time or again, 2 bombs or empty fuel tanks."------------------

H2 needs Oxygen to ignite. Surely you know this.

Good for you, he was talking about Hydrogen.
Sucks you were scared though.
I actually produced hydrogen through electrolysis and gas reforming on a very large scale. We used the hydrogen to make ammonia, mostly.

"Sucks you were scared though"
Says a person who's apparently never worked with or had any training with stored supercooled gasses in liquid form.
Shits dangerous, and I challenge you to find someone who is experienced with either and is as carefree as you think they should be.

Here, educate yourself, tough guy.

You remind me of someone I worked with who was carefree with cryogenics. They are now missing part of their right hand because they didn't think liquid oxygen was dangerous.

You brought up O2 and your brought up cryogenics.
Also, if you don't know the difference of how O2 and H2 act at different temperatures and pressures, you should probably just let it go.

They always deflect, throw up straw man arguments, and then claim supremacy.

Again, you still haven't explained how liquid oxygen isn't dangerous and should not be treated with extreme caution, and you haven't explained with any evidence how liquid hydrogen and liquid oxygen are different with regards to their hazards, storage, and handling.
So typical of an ignorant troll trying to salvage an argument they realize has gone way over their head.

then accuse me of a logical fallacy.

19. "We are talking about cryogenic liquids"

Except none of the 4 H2 cars now on the road use LH2

Neither do the trains in Germany and soon France

Neither do most H2 drones

None of the >15,000 H2 powered forklifts in use right now use LH2

The H2 bicycle uses gaseous H2

And finally, Germany's H2 submarine doesn't use LH2

Why is cryo hydrogen being brought up?

It's supposed to be SCARY!!!

That support your "theories" that
Liquid O2 isn't dangerous and nobody should feel frightened in the least when working with it,
And cryogenically stored H2 and O2 are nothing alike in that
1. they don't both pressurize storage vessels while transferring into a gas from a liquid unless vented,
2 That both liquified O2 and H2 both won't cause severe injury in case of physical contact with unprotected skin,
And
3. That both when spilled wont create an extremely hazardous atmosphere if in a confined space

You thought that your experience with O2 is equal to experiences with H2.
I don't expect you to realize that, but it's there for everyone to see.
