In this paper, two binary salts, NaNO3 – LiNO3 (46% – 54%) and NaNO3 – LiNO3 (40% – 60%), were investigated to assess their suitability for medium temperature heat storage. The thermal properties and long term stability under multiple cycles of each binary salt pair were investigated using Differential Scanning Calorimetry (DSC). The chemical stability at elevated temperatures was tested using a Thermogravimetric Analyser (TGA). Both binary salts analysed have suitable melting temperatures (just under 200 °C) with relatively high latent heat values (>220 kJ/kg), both exhibiting good thermal and chemical stability.
