  It's called a gravity battery and this is far from being the first.

    https://www.autonocion.com/us/tower-china-wind-farm-power/ https://www.autonocion.com/us/tower-china-wind-farm-power/ claims it is the first commercial one. I can't find others that are not either prototypes, trials or failed commercially. This design looks to be rolling out in several countries already, which is pretty good as these things go considering their prototype was built in 2020.
