what is the resistance of hydrogen?
Depends on the container's dimensions. Specific resistance is often expressed in &Omega; cm, which means that a cube with 1 cm sides of a 1 &Omega; cm material will have a 1 &Omega; resistance between opposite sides.  

At 1 atmosphere a gas is mostly empty space, with here and there a molecule. I don't think that hydrogen under those conditions will be much different from other gases (possible with the exception of noble gases). I expect a value of at least several 100 M&Omega; cm, probably a couple of G&Omega; cm.
