The choice is never between this storage or no storage. It is always between this storage and all the other storage choices. Whichever is cheapest while matching local requirements best wins. Over time, the winner changes, so each time you add more storage, you choose over again, and may end up with several different kinds, which can be an advantage if they have different characteristics. There will be a hell of a lot of money made in meeting people's storage needs. I will be betting on producers of factories to synthesize ammonia.
