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
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.
