well, i do know that paintball gun tank filling systems (not the c02, the nitrogen tanks) use extremely high pressure storage tanks and compressors.
diving tank compressors operate up to about 3000psi, so thats a good place to stay. again, as chemelec said, isolate your anode and cathode and get rid of the oxygen.....store just the hydrogen,.
