Does This 'Hydrogen-Powered' Luxury Boat Breaks the Laws of Physics?

Does This 'Hydrogen-Powered' Luxury Boat Breaks the Laws of Physics?

So if the diesel generator has a thermal efficiency of, say, 40%, we are already wasting 60% of the energy contained in the fuel. Then the electrolysis process to split water and extract the hydrogen is going to waste some more energy because it won't be 100% efficient. And then, however they use that hydrogen to power the boat (they don't make it clear if they use a fuel cell or if they burn it in an ICE), they're going to have more losses. Not having more details on the hardware that they claim they use, I can't be more precise than that, but I can guarantee you that unless this boat breaks the laws of physics, that it guzzles more fuel than if it was only powered directly by a gas or diesel engine. Yet they claim no CO2 or PM emissions, so what's the source of energy used to split water? Maybe unicorn dust...
