Re: Best choice of FTL fuel?

Hydrogen and Helium diffuse at about the same speed through pretty much
any barrier unless there's a chemical affinity between the metal and
hydrogen, as there might be for palladium filters. The rate of diffusion

It's counter-intuitive but the size of the molecule does not have a
significant effect on diffusion rates.

Maybe the "channels" in most materials are significantly wider than
most gas molecules?
