Again: current day CNG ICEs don't actually have "fuel tanks bigger than the car".
- fuzzfactor 8mo agoThat's because they use high-pressure tanks. Actually higher working presure than regular welders' oxygen tanks. Too bad the higher the pressure, the heavier the tank, especially steel. I had a pretty good job offer from a company that was going to start building CNG tanks out of carbon fiber. This was a few years before the failure of the Titan submersible. CNG has made some progress since then, here's the kind of thing there is now: https://steelheadcomposites.com/sites/default/files/2024-01/CNG-Brochure.pdf https://steelheadcomposites.com/sites/default/files/2024-01/...
