Hydrogen power could be coming to the superyacht scene in a pretty spectacular way, with Dutch company Sinot's latest concept just unveiled in Monaco. The Aqua is a 360-foot (112-m) monster that would run entirely on liquid hydrogen and offer a range of 3,750 nautical miles (4,315 mi, 6,945 km). And boy, is it nice to look at from just about any angle.

The Aqua's huge hydrogen tanks are one of its many design highlights; to visit them, you take the spiral staircase in the center of the boat down to the lowest of five decks, and there they are, glowing with blue light. Two 28-ton, vacuum-isolated tanks designed to keep the liquid hydrogen stable at -253° C (-423.4° F) sitting behind strengthened glass for safety.

These tanks can split off power at up to 4 MW, powering two 1-MW electric propulsion motors and two 300-kW bow thrusters for tighter maneuvering. A 1.5-MWh battery pack acts as a buffer, providing instant access to power and running the ship's electrics, and is charged as necessary by the fuel cell.

Wow! From an old hydrogen guy

“... and offer a range of 3,750 nautical miles (4,315 mi, 6,945 km).“

So, how far is it from Seattle to Monte Carlo or Singapore, or is he just going to cruise from Seattle to Cabo?

At about a 800ish/1 expansion rate for liquid to gas, that glass wouldn’t make much difference.

Hydrogen is wonderful until it gasifies. Ala Hindenburg.

The German Zeppelin Hindenburg was filled with hydrogen gas. Just sayin’

Are we sure that's the safest option?!
