Hydrogen even diffuses through (and into) metal - seems not doable, not cheaply and without maintenance at least.

- credit_guy 2y agoHelium atoms are actually smaller than hydrogen atoms, and much smaller than hydrogen mollecules.
- adrian_b 2y agoWhile that is true, there are metals through which hydrogen can diffuse faster than helium, because the hydrogen molecules dissociate and ionize when entering the metal and the hydrogen ions diffuse through the metal individually.
