but when you can store it

Lithium batteries are insanely ineffective for energy storage. Compare them by energy density with gas/diesel/LPG/LNG.

Lithium shit is forced on us only because of its main business property - small and limited number of charge-discharge cycles. Any customer will have to continuously pay shitloads of money if it locked to that shitty technology. All that pushing of solar and wind garbage is an integral part of that lithium swindle.
