Suggest a lot of practical engineering hurdles (as foreshadowed) need to be overcome first before this fantasy ever takes flight and on a commercial scale!
We haven’t even sorted it yet for ground/sea transport.
What’s wrong with continuing to utilise propellants that are a liquid at normal temperatures; or alternatively as Elon Musk found out (and switched to) – its much easier/convenient to use hydrogen, in the form of methane (CH4).

But of course, the current boondoggle hydrogen green-dream continues.

Agree with the naming of the first prototype aircraft.

Water is THE most powerful greenhouse gas, but usually gets ignored because it precipitates out in a few days, despite constantly being replenished. However, producing hydrogen, which when burned will create water, will add to the amount of water vapor present at any time and will have to be dealt with!

I suggest that the first prototype to be flown be christened the Hindenburg.
