Subject: concrete holding hydrogen gas.

I would like to know how to calculate how high I could compress hydrogen gas 
theoretically into a spherical cement/concrete container with rebar inforcements 
would withstand.  I am in eugene oregon, at about 500 Ft above sea level if this 
helps.  The container would have about 1000 cu ft in area empty.  Please explain 
in k.i.s.s. format so that i can pick up all the information easily!  Thanks!  Have a 
good one!
