Wrong

Hydrogen production and transportation doesn't make sense unless it's done locally (ex: produce it at a port, transport it to fuel the ships stationed at the port). Hydrogen is pretty much impossible to transport long distance without wasting so much energy that it doesn't make sense to do it in the first place, then think about how hard it is for us to prevent leaks of petrol of all things, now think about the leaks if we're transporting hydrogen instead.

You have inverted reality here. It is much easier to transport hydrogen long distances versus electricity. Pipelines are cheaper than HVDC cables. You can actually ship hydrogen across oceans if necessary. It is electricity that has to be made locally, but hydrogen can made anywhere it is cost effective.

Hydrogen gas will leak though steel since the molecule is so small while making it brittle and incapable of handling pressure through hydrogen entitlement. It's not trivial to ship. Power lines are cheap and transport extremely high power density.

Only for certain types of steel. And there are many materials that are impermeable to hydrogen. This is mostly a marketing argument rather than one based on fact. Pipelines are far cheaper and send far more energy than high voltage wires.
