Hydrogen vs. Battery Electric Cars

Good video, points are kinda same in all the comparisons so I won't go into 1. vs 2. argument which is better. But I'd just like to touch on a subject around 5:45, compression is mostly done with machines but there's many passive ways to do it also. For example a passive https://en.wikipedia.org/wiki/Trompe Trompe and other natural elements could be made to provide pressurisation, and other part was "cooling the hydrogen" which to me sounds like free energy - not a thing which we should waste energy doing so in the first place. But anyways this was my input, looking to hear more about hydrogen and it's useability in arctic areas (batteries tend to deliver power poorly in -40c temps) and if it has any place there vs. electric battery cars.
