> Hydrogen embrittlement is a phenomenon that occurs when hydrogen diffuses into a metal and weakens it, making it more susceptible to cracking. H2 for transportation is pressurized at 500-700 bar-`7,300-10.300 psi.
hydrogen embrittlement is an issue when using hydrogen as a fuel for transportation. The hydrogen atoms can diffuse into the metal components of a fuel cell or hydrogen fuel tank, making them more susceptible to cracking. This can lead to premature failure of the components, which could pose a safety hazard. Special alloys and coatings are required to lessen the danger. Hydrogen for transportation is closer to rocket technology than gasoline or diesel.

Well that's something new
