there are definitely people looking into high pressure air as a way of storing energy
I just think: we already have plugin hybrid vehicles in the form of petrol-electric. Why not petrol-air? Mainly because one produces waste heat & the other needs additional heat.
I have to inform you that I already had it more than 30 years ago, however...
Another idea is to store energy and at the same time use as engine in a car, a couple of fast rotating flywheels.
It is very inefficient.

Plus they don't 'absorb' waste heat.
