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)

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
