1. A process for thermal storage comprising:
(a) providing a thermal storage reservoir with a first liquid having a first temperature and a second liquid having a lower temperature than the first liquid;
wherein said first liquid and said second liquid are layered within the tank due to a difference in density between said first and second liquid and wherein said density difference is due to a difference in composition, concentration, or both;
