National Grid Battery
So we know the issue, green energy is not consistent or might not be available when its actually needed so we need some really massive batteries on the national grid so we don’t have to turn on or up the dirty power stations.
So far we have hydro, so when the demand on the grid is less then the generation capacity we can pump water up into upper elevation reservoirs and when the power is required it drops to the lower reservoirs to generate hydro electricity.
Now we have a new battery, is called cryogenic storage. Its uses excess generation capacity to chill air and when the power is required the warming air expands and drives the turbines.

We need more of this sort of thing.
