Hydrogen combustion doesn't produce co2, optimize a petrol-fueled ICE all you want and it's still a problem WRT emissions. I think the assumption is that hydrogen fuel would be produced via "green" electricity sources like wind/solar/nuclear.
There is that subtle issue of how do you get hydrogen.... Takes energy to make it.
I wouldn’t be surprised if all those wind farms that have popped up in the mid-west were actually owned by some subsidiary of an oil company.

When I think “Jerry can” I think the very specific rigid 20L vessel. I guess we can call other things a Jerry can too. I’m curious if these are legally allowed in Canada. If so they seem decent!
I'd also search out "off road" people and forums, though they may not specialize in your vehicle, they probably know the various rules and regulations.
https://www.zuksoffroadcanada.ca/Gas-Tank-15-Gallon_p_997.ht... does exist, so I'm sure there's things out there. People modifying vehicles for Nunavut or the Australian Outback would be places I'd start.
So do things like : https://masterhitch.com/catalog/truck-suv-accessories/auxili... but I'd be a bit wary of bolting gas tanks to the rear bumper/trailer hitch myself.
And many rules will stop applying once you are "off road" whatever that means in your area.
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…
Batteries needed electric vehicles are still expensive and seem to essentially be the bottleneck for mass change to EV. The infrastructure needed to support battery electric vehicles seem to be expensive/complex to run sufficiently well in practice. In the US Tesla's supercharger network is often cited as a moat against other manufacturers. It's not even building the chargers - it's maintenance and compatibility. Cha…
Tesla already announced they were going to make their us charging network support the us ccs standard for charging. In Europe they have been rolling it out to all cars (that all use the same standard plug) for a few years. Tesla chargers in Europe that are already working for competitor cars are not ruinously expensive. The reason tesla got so much market share was their competitors are very threatened by the transition to a completely new drive train, making their billions of dollars in investments in design of ICE engines, but also the entirety of mufflers, alternators, emissions controls, spark plugs just worthless scrap over time. Of course they all wanted to keep doing something like an ice engine, Toyota wanted hydrogen, etc.
Somewhat off-topic: why "2k kilometers" instead of 2 megameters? I do realize that in daily life people rarely use distances of that order of magnitude, but the semantic connections between kilobits megabits, kilowatts megawatts appears to be entirely accessible to essentially all adults, so why use the awkward "thousands of kilometers" instead?
This is nothing new, I remember an episode of “That’s Incredible!” from the early 80s that featured a bunch of college students that created a car that got 100 miles per gallon. The problem has always been that advancements in clean power get bought up by the oil companies and buried. That sucks for consumers in the hear and now, but it is a really smart move by big oil - if the petrol gravytrain ever runs dry big oi…

Looks like the worst of both worlds at the first glance. However depends by the costs of batteries. In a world with an abundance/excess of green energy but expensive batteries to store it hydrogen makes sense. The conversion of electricity->hydrogen->electricity is quite inneficient so batteries better be cheap enough otherwise we will go the hydrogen way for cars as well.
I think you’re under the impression that it requires the hydrogen generator? You can use the hydrogen tank if you are without somewhere to charge the vehicle, but you can also just use it as a traditional EV and charge as you normally would.

Counterpoint: I can't even refill my damn inkjet without the manufacturer doing their damnedest to get me to pay multiples for what's essentially commodity ink. I have no faith that hydrogen won't work the same.
There is little political will to regulate printer cartridges. Cars on the other hand are heavily regulated.

I won’t speak to the extent that oil/fossil fuel business has suppressed clean energy (not that I’m disputing it, I think it’s more complicated though and don’t care to comment on that in this context). But I will say I’ve seen huge wind farms built atop huge, now-idle oil operations eg across large parts of central Texas. Never looked into whether they’re owned by the same oil companies but it sure wouldn’t surprise…
