I’ll note that right now, this is a seasonal issue, associated with moderate springtime temperatures when there is a lot of sunshine available.

There is a reason why energy based energy storage is not more developed right now (with the exception of Pumped-storage hydroelectricity). It’s not very dense at all.
A 15 tons block of concrete that goes up 100m can only store 4kwh of energy. A 4.5kwh battery cost around 1600€.
Gravity based energy storage seem simple and elegant at first but you go into the details you realized that is far far les efficient than regular chemical battery. Unfortunately.
