It's just a matter of scale. make your tank 4 times as big and the surface area for leakage only grows by a factor of 2. also there is already a natural gas grid that can take a lot of hydrogen without modification. Again this really only ever makes sense if you have an absurd energy surplus as a sort of last resort way to use energy that would otherwise go unused. In terms of actually being a desirable power system it seems like a complete nightmare to deal with unless you need to go really far out on the gravimetric energy density front with very low power density all while having a fraction of the efficiency of battery electric

I think your maths is off. For the same shape, surface area = volume ^ (2/3)

[iconosynclast]

ah yes sorry got mixed up a bit there. a doubling in linear size leads to a quadrupling in surface area and an 8 fold increase in volume and then I somehow got confused from there m) nevertheless increasing size improves the situation

[heavenlyblue]

How does that improve the situation? One spark and it all goes boom. It’s not the relative size of the leaks to the volume of storage that matters, it’s the fact that even a small leak will go boom very easily.

Nah, in this context they are talking about hydrogen having so small molecules that it escapes from all containers you put it in. Increasing size of container decreases relative leak per volume (due to previously explained math).

Problems of the booming nature is a different topic.
