I honestly do not think there is anywhere in the world that has easy access to the ocean, a large potential hydraulic head, and a pre-existing elevated saline lake to work with. Maybe somewhere in the Atacama? Is there enough power demand in the region to make it worthwhile? [edit] I did find a very small seawater pilot project that was dismantled last year in Okinawa. https://en.wikipedia.org/wiki/Okinawa_Yanbaru_Seawater_Pumped_Storage_Power_Station https://en.wikipedia.org/wiki/Okinawa_Yanbaru_Seawater_Pumpe...
