Isnt it extracted from fossil fuels?

How can you call hydrogen eco when it is used to keep on drilling and building new infrastructure for the fossil fuel industrial complex.

Textbook case of greenwashing?

That hydrogen must be produced somehow. This yacht refuels only where the H2 is produced using 100% renewable power?

Of course, non of this mentions the (no doubt enormous) GHG emissions embodied in the yacht's construction? Its materials? The shipyard workers driving back & forth every day over the course of its construction? All the maintenance that will be done on it for years to come?

Never mind billionaire users flying in on their private helicopters. Or all the luxury foods presented to their guests.

Let's be honest: "superyacht" and "eco-conscious" does not compute. Superyachts are wasteful by definition.

Ok... if ultra-rich 'need' to have their superyachts, a H2 fueled one might be preferable over a diesel powered one.
