I think compressed air is a better way to go.

Go for what?

The energy density of compressed air is ludicrously low.
Typically one sixth of lead acid or worse. 15 wh/l is hard to acheive.

It is the energy per pound

kilograms please. Pounds are used only in Myanmar (Burma), Liberia and oh yes,
the USA.


not the energy per unit volume that matters. Others have seen that it is a
good light way to store energy
and get the power out quickly when needed.

You can't say that in isolation. If the volume becomes excessive (which it does
with compressed air) it's equally impractical. And don't forget the weight of
the containment either (also a big problem - one of many - for hydrogen).
