Long-term heat-storage ceramics absorbing thermal energy from hot water.

ABSTRACT: In thermal and nuclear power plants, 70% of the generated thermal energy is lost as waste heat. The temperature of the waste heat is below the boiling temperature of water. Here, we show a long-term heat-storage material that absorbs heat energy at warm temperatures from 38°C (311 K) to 67°C (340 K). This unique series of material is composed of scandium-substituted lambda-trititanium-pentoxide (λ-Sc _x Ti_3-x O₅). λ-Sc _x Ti_3-x O₅ not only accumulates heat energy from hot water but also could release the accumulated heat energy by the application of pressure. λ-Sc _x Ti_3-x O₅ has the potential to accumulate heat energy of hot water generated in thermal a
