Actually, it is a very inefficient method. Compressed air is a horribly inefficient method of energy storage. Too much energy goes into heating of the air during compression. That energy is lost.
The basic idea isnt too bad.

Yes, but according to the article it takes two minutes to fill the air tank. Compare that to six to eight hours to recharge a battery pack. Also it gets 125 miles on average per refill. That’s also comparable to an electric car. Plus there is no need to buy an expensive battery pack when the old one dies.
So as an alternative method for storing energy for a cars propulsion it does beat electric as far as I am concerned. And I can imagine a braking method that uses a pump to put air back into the air tank. That would be similar to the regenerative braking on some electric vehicles also.
That to me makes it an idea that isn’t too bad.
