Dear All,
I am reading storage of Sustainble energy is a big problem due to phase difference of demand and supply.
Why simply pump sea and lake water up to a mountain lake, store it,  and use it down stream energy  whener you need... Store energy as potential energy...covert it electrical whener you need it...
