This is the real future for EVs. Quick refueling means you can actually take a proper road trip (at least when fuel stations are built), and it may actually be practical for a country like Canada (big, sparsely populated). Also it needs less batteries, which is likely to reduce its ecological footprint.

I thought the issue with H was transportation: a critical hurdle for new fuel technology adoption is safety (as seen in Tesla's quick and overprotective addition of an armored underbody on the Model S when a few stray stories of crashes caught flames in the press). Tankers of H hurdling down our freeways? I feel like range anxiety on full-on EV's will dissipate in the next few years as we get to 300+ miles on a charge. After that, what's the downside?

  The dream expressed in the article would be to have high-pressure electrolysis to produce hydrogen on-site. I won't disagree if you think that 300+ miles/charge will come first.

    Electrolysis is a fairly inefficient way to produce hydrogen. If you've got enough energy to do electrolysis, then you've got enough energy to run a motor. The only technical reason you'd want to use hydrogen is that you can do combustion and long-term fuel storage. It would be valuable if you were using something like sunlight to produce hydrogen, since sunlight can't really run a car.

There's no reason you can't take a "proper road trip" with a Model S these days. Stopping for a break every ~3-4 hours isn't a huge issue and 120kw charging goes surprisingly quick. Heck, when I was at a supercharger yesterday I barely had time to grab coffee before I had the 40% charge I needed to make the end of my trip.
