Isn't hydrogen difficult to store? I've heard that it will leak out of just about everything.

  You might be thinking of helium, which becomes a zero viscosity superfluid when cold enough.

    Hydrogen can diffuse through certain metals and weaken them [1]. Currently, hydrogen storage is costly and tricky for a number of reasons [2]. It’s also very important to avoid leaks into enclosed areas since it’s extremely flammable.

      Oh, didn't know it'd leach into metals, that's interesting.
