Industrial compressed air isn't usually compressed enough to make a good storage medium - usually people talking about compressed air storage are dealing with 200+bar, whereas industrial compressed air is only ~8 bar. That means you need really big tanks.

Compressed air motors and compressors are also pretty inefficient and large systems leak like a seive. They're used for convenience, safety, size, and light weight, not efficiency. Battery cordless is much more efficient.
