That is, unless declining battery costs make storing PV power more economical. James Nelson, a California-based energy modeler with the Union of Concerned Scientists, says this intrasolar race will be good for the environment: “I’m glad we have multiple technologies that can help the transition from gas power plants.”
I agree with his remarks in principle, but really, there is far more abundant Na/K in the earths crust than the currently touted Li. And the Li would probably go to better use in ~65C melting point salts(by weight LiNO3 5%,NaNO3 6%,KNO3 23%,CsNO3 44%, Ca(NO3)2 19%, although the Cs would be the limiting resource if the competition for Li usage wasn't there)[0].
