But isn't most of the new solar generating capacity PV?
If so you cant really use thermal storage with PV, cost effectively.
If you are working with a solar driven steam turbine then thermal storage is a great idea and does not require the smart grid.
As far as storage batteries you cant use lithium, its far too expensive. You can use Ni it will be expensive, but then there will be a lot less around for electric car and hybrid batteries.
Take away lithium and nickel whats left?
On the other hand there is no shortage of lead for the time being.
