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.
