Hydrogen is hard to store in the gaseous state. The extremely small
molecular size makes it possible for leaks to occur thru openings too
small to pass molecules of other gases. Any such leaks are tough to detect
until too late (i.e. kaboom!). Think exploding car batteries due to too
rapid charging causing hydrogen buildup.
I'm not trying to discourage you but be VEEEERRRRYYYY careful and do a lot
of research on handling and storing hydrogen.
Last.....put me in your will.
