Abstract

Among the potential materials proposed as suitable for thermochemical heat storage, ABO3 perovskites merit significant attention for high temperature applications in concentrating solar power plants. The specific enthalpy of the reaction is a key parameter to establish the storage capacity of the system, and accordingly determines the potential impact on decreasing related costs associated with the volume of the system. Discrepancies in the referenced enthalpies may arise from different sources like the experimental sets-ups for measuring thermodynamic properties; protocols applied or the origin of the samples. This work presents a round robin test conducted by seven institutions in order to establish a standard methodology for the measurement of enthalpies of relevant thermochemical processes at high temperature. The initiative was organized within the Working Group on Thermal Storage (Activity on "Materials for Thermal Storage") in SolarPACES Task III.
