The point simply is, as long as renewables almost never exceed the grid load, there isn't much to store. Yes, as renewables are exceeding the grid load, storage becomes more important and then storage will be pushed harder. It would also help if some regulations limiting the commercial success of storage would be dropped, like paying the EEG fee on stored electricity.
That said, storage is growing, a 1GW DC line to Norway was put into operations recently.

Owners of renewable sources may be less happy to switch them off. (In the EU) storage can take the place of fossil when fossil becomes expensive enough. No need to give more subsidies to storage than renewables would get. Excess amounts of renewable can also be used for other purposes, such as producing green hydrogen.
