That wikipedia page answers everything you need to know about compressed air energy storage.

In 2018, the tech couldn't compete against lithium ion, and the price of lithium ion continues to fall 10-20% per year.

Compressed air and that concrete-block-stacking nonsense that keeps getting press are just magnets for uneducated investors.

That wikipedia page says:

> Compared to traditional batteries, CAES systems can store energy for longer periods of time and have less upkeep.

Sometimes the cost per MW/hr or equivalent is not the only metric worth thinking about.

Plus, always a good idea to hedge: against lithium shortages / gouging and battery supply chain disruptions.
