Unfortunately, it has the same infrastructure problem as EVs. The ZPM MDI Air Car stores enough compressed air to generate 22kWh of equivalent propulsion. A standard gas station pump, which probably draws no more than 110V at 15 amps, would take 13 hours to fill that tank, IF the compressor operated at 100% efficiency and at maximum power for the circuit.

This means much larger compressors, using much higher amperage. Begins to sound a lot like the same infrastructure problem that EVs have, doesn't it?

BTW, a Tesla-like pack of 18650's with supporting circuitry and rackage weighs about 373 pounds for 22kWh.
