I think that's helium.  They way they get it commercially is to start with 
gas wells that have lots of it.  I think some of them are 4%.  Then they just 
push it through quartz.  I think they use high pressure.  I'm not sure if 
quartz is special or just handy and works.

Hydrogen is weird in that it infiltrates lots of metallic crystals.
