2k isn't bad, but it's something that ought to be almost achievable with a modern and optimized ICE car as well nowadays.
Some time ago I saw a presentation from the chaos computer club where an expert on the matter explained there is a lot of misunderstandings about hydrogen technology as an energy source and how is gonna useful for society and why it is necessary. In a nutshell some industries that currently rely on natural gas cannot switch effectively to electricity, hydrogen seems to be the only solution at the moment. Regarding tr…
Hmms. 2k km isn't bad, but i don't consider this amazing either: my 12-year old big and heavy car can do 1300 km on a full tank. Sure, that's in ideal conditions, but so is this. And there is plenty of simple improvements that would make my car more efficient (weight & aerodynamics mainly). 2k isn't bad, but it's something that ought to be almost achievable with a modern and optimized ICE car as well nowadays.
I think the assumption is that hydrogen fuel would be produced via "green" electricity sources like wind/solar/nuclear.
Hydrogen is very appealing, but the lack of a distribution system makes it highly unlikely. It's hard to see Toyota and Honda continuing to make hydrogen cars much longer. Maybe for trucks?
Distribution can be figured out, same as it was for fossil fuels and as it was/will be for electric energy. It would be a chicken and egg problem, for sure, however hydrogen has some big pros over electric, in that you can fuel up quite rapidly and get longer ranges, and doesn't have the harmful emissions of fossil fuel (how to produce the hydrogen in the first place is another issue, but the same is true for EV "fue…
The problem with hydrogen is the lack of infrastructure. EVs have suffered from the same problem too but are arguably over the hump. Starting from zero again with range anxiety and no fueling stations sounds exhausting.
On top of that it’s way more difficult to install a hydrogen charging station than an ev-charging station. On the other hand, in Poland at least, natural gas charging stations managed to get enough traction - every gas station ofers LPG here.

What about using hydrogen as a generator for an EV like in the Hyundai 74 concept? I’m far from an expert but something like that, at least intuitively, feels like a nice compromise with having portability of fuel, but still allowing for alternative power sources via electricity (like if grid power was sourced via solar, hydro, wind, etc).

A normal range for cars these days is 500-900km on a 40-60L tank, as carrying excessive fuel is bad for efficiency. 2000km is a very impressive metric, all things considered.
