H2 tank leakage
Another question I have on hydrogen is regarding the energy storage problems:
wont hydrogen, stored in a conventional metal (SCUBA) or steel tank, leak out of the tank if stored for say a day (24 hours), and how much of it will leak out of it (in %) depending on the pressure the hydrogen is stored inside it ?
Pressures I'm thinking of are: 7 bar, 250 bar, 350 bar and 700 bar.
This would matter if you would ever want to use hydrogen in say a car, and would not drive sufficient distance to completely drain your tank (and so instead would keep whatever hydrogen remains after driving, stored in the tank in your garage untill the next day).
