Odd that somebody who is trying to school me on the realities of renewable energy is unaware of this, but here you go:

>>if grid scale storage were prohibitively expensive or impossible. >It's currently both
For something that is prohibitively expensive and impossible we sure are seeing a lot of it rolled out.
>"Cheapest" option is pumped hydro storage. To cover Europe's need you only need to build 70 1.5 GW hydroelectric stations at a cost of $92 billion
Meanwhile, Hinkley point C is projected to cost $28 billion and for that we will get just 3.2GW.
Europe used 2785 TWh last year. Even if you assumed that storage is free, that still requires a minimum of 317GW, which would require about 100 Hinkley Point Cs, which would cost $2.7 trillion to build.
$100 billion would be a bargain.
