You clearly don’t yourself, since tanks are made of carbon fiber. Embrittlement is very alloy dependent too. Choose the right alloy and it is a non-issue.
There are vast quantities of suitable underground caverns. It gives many orders of magnitude more storage capacity than any other idea, including pump hydro (which is significantly more geographically limited).
I don’t think you understand how embrittlement works, or what the problem is. Define “very little”, and over how long of a lifespan?
Well, that’s not very reliable for setting up grid storage is it? I mean, you have to have a suitable cavern.
Still waiting on some sources… so far you haven’t provided any information, only opinions.

It’s sad that you claim knowledge, but you can’t be bothered to google it. There are many studies out there like this one: https://www.sciencedirect.com/science/article/pii/S2589004223028481
