Ain't no way, no how they're getting 200 mi per air charge. A 5 liter bottle of air compressed to 200 bar (2,900 psi) has 530 kJ of potential energy, and that's if you can extract useful energy from it all the way down to 1 bar. A gallon of gasoline (about 3.7 liters in volume) has 125,000 kJ of energy.
However, compressed air has great potential for use in hybrid buses and frequent-stop large vehicles such as trash collection vehicles. It is much easier to rapidly compress and store air than to generate and store electricity in large vehicles. Further, the compressed air system has a longer life span and lower maintenance costs than the equivalent electric hybrid, and the advantages improve as you scale up both systems.

If refueling in quick and you can get near 200 miles per fill up
what's not to like. No pollution, no carrying the extra weight of gas,
iron engines or batteries and the extra structural weight they require
