hydro can win if all the stars align. Electrochemical is the real winner though.
This is just a grift. I doubt this thing will ever materialize. It seems like every month a new gravity storage company emerges and none of them go anywhere with their promises.
As I posted elsewhere, my power company is installing 200MWh of storage on 10 acres. It will take them about 6 months to build it out (they've not started construction yet, they project they'll be finished by june. They just finished getting all the approval they need to start work).
That sort of land efficiency and deployment speed won't be matched by any gravity storage system.
Costwise, it'll probably be in the range of $24,000,000 to install (maybe more like 30M with power electronics requirements).

I'd like to understand why. Just too much complexity? Gravity storage is compelling to this layman.
