Why not hydrogen?

• cyberax 2y ago
  Liquid hydrogen is impossible to work with at large scales, it causes embrittlement, leaks like crazy, has poor volumetric energy density, requires storage in vacuum-insulated tanks, etc.

    Molecular hydrogen does not cause embrittlement (neither gaseous, nor liquid). This is a concern in certain chemical reactions that produce atomic hydrogen, but not in any storage applications.

      ???? It certainly does. The higher the pressure, the worse it gets. And it absolutely applies to storage. There are companies that sell various technologies for hydrogen-resistant coatings for pipes, for example.
