According to the present invention, (i) at least one first metal containing material comprising at least one first metal compound comprising nitrate ions, nitrite ions or both; (ii) at least one second metal containing material comprising at least one second metal compound; And (iii) optionally water A thermal energy storage material (TESM) system (and associated method) for storing and recovering latent heat to be renewable, comprising: Wherein, when water is present, the water concentration is less than about 10 weight percent, the TESM has a liquidus temperature (T L ) of about 100 ° C. to about 250 ° C., and the TESM is from 300 ° C. of at least about 1 MJ / l. When used in a system that generates heat, indicating a heat storage density to 80 ° C., at least some heat is captured by TESM, stored, and subsequently released for use, the system generally having a temperature of about 300 ° C. In corrosion resistance. |
