The reason why I said what I did is because of HOW you get Hydrogen. You don't mine it, you don't drill for it, you don't harvest it, you manufacture it either from electrolysis of water or the steam-methane reforming process of Natural Gas.
Thus, Hydrogen is in and of itself not a fuel source, it is an energy storage medium created from another energy source.
The Sun has a lot of Hydrogen.
Why not just mine it there?
While electrolysis and Nat Gas extraction are reasonable ways to produce hydrogen they have gotten to be a bit old school in terms of industrial production. The guys I buy industrial gasses from now draw H, O2, CO2, CO from free air. Since they all liquefy at different temps the process starts by HP compressing then chilling to the point of first liquefaction. Draw that off then chill again and repeat.
More importantly this whole idea is freeping, bleeping , stucking,bungholio bad. Everybody who uses cryogenic gas knows the fire marshall will ream you a fresh one if your storage /work space is not well ventilated. Cryogenic gasses slowly bleed off while in storage. Imagine fueling up your Hmobile, driving home, parking in your weather tight garage, then lighting up a cigarette next time you go out to take a cruise? Yeah, everybody needs one of these. It wont matter if you got the covid clot shots.
