This is an insane suggestion if you had a concept for how expensive batteries are and the scale of flexibility issues on the european grid.

It also does nothing to help transmission grid frequency stability and control.

they dont help grid stability via inertia of spinning masses, but PLLs and the like exist, where you can control frequencies and phases without a spinning mass.

you dont need to burn gas to have a flywheel either

Batterie prices are falling constantly and grid sized battery production has not even started. The focus was and is mobile batteries.

So expect prices to drop further.

Also yes, batteries help very much with grid stability as they can give steady power on demand anywhere. Have lots of batteries everywhere == lots of on demand grid stabilizers.

Could pumped-storage batteries help in that case?
