Just come to think of it, in a 4 stroke ICE you always have 2 piston top and 2 pistons bottom, iow, 2 x power strokes at once and . . . . 2 x the power stroke with the piston having a power stroke every time it reaches TDC. or you can use a smaller engine and do the same amount of work,
In summary: you can use 1/4 of the energy that one would need from gas to get the same job done ? ? ?, right? or 4 time less energy ( being compressed air) and getting the same power as from gas. (Sorry not to sure how to put it.)
There is a lot of other technical stuff to be thought about I know not my forte,
but just think, you can have a 2 or 3 stage compressor on board running of solar ( for the 2 hours you go shopping or 8+ hours working) or go to the garage they already provide 2 - 3 bar of pressure on the airline, your on board compressor just finalize the pressure.
The owner wont take kind to that as he already lost you as a customer on fuel/service sales, and now you are cutting into his profit too. But you can have a little compressor running from solar/SG at home filling up a tank that you can use.
Well just thinking/dreaming - please don't wake me !
