Batteries are not a feasable seasonal storage. They can store for a couple of hours, no more. For seasonal storage you need a hydrogen economy. H2 is very very expensive and has never been rolled out at scale. Not a single large gas turbine to burn pure H2 has ever been build. In the middle of a crisis it's better to go for proven and economic technologies than trying to invent something completely new and untestet.
