Yeah the US will lag behind on this.

Other countries are better positioned. e.g. UK has really spiky wind energy. Right this second more than half the grid is wind. Which is both cool and problematic for managing the grid.

Grid scale cheap storage would dramatic help manage that chaos

I surprised can’t, or rather don’t, make more use of tidal energy.

That and low density storage located at sea with the turbines.

Spain suffered a black out partially due to the lack of momentum (spinning generators).

For Europe to get rid of more fossils without putting the grid at risk we will need more storage.
