What grid scale storage are you referring to? The only one I know is pumped hydro, and that's quite iffy efficiency wise, can be expensive, and you need the landscape to do it (I'm personally in a very flat area with nothing for a good thousand miles).

Legit question too. I know we have a bunch of nascent tech, but haven't heard of anything at scale.

I didn't use the term "grid scale storage", I used the terms "short term storage" and "long term storage". Which were you asking about?

Short term storage is batteries.

I called long term storage "expensive" and implied that it's the 3rd step so into the future, so that opens up the options for nascent tech.

Note that you don't need much of a slope to do pumped hydro. For example: https://en.wikipedia.org/wiki/Ludington_Pumped_Storage_Power...

I feel the need to note that if we can't hold that amount if water for power why is it we seem to think we can do so with mining tailings?

There seems to be an obvious contradiction extant in the markets....
