Within the conventional two-tank molten salt energy storage system, a configuration involving two distinct tanks - a hot tank and a cold tank - is established. The molten salt mixture, composed of 60% sodium nitrate (NaNO 3) and 40% potassium nitrate (KNO 3), undergoes heating via a solar tower receiver positioned at the central solar tower.
