High-Temperature Thermochemical Heat Storage Performance of CaO Honeycombs During CaO/CaCO3 Cycles

Abstract: Thermochemical heat storage based on calcium looping is a promising technology for high-temperature solar thermal applications. CaObased materials suffer from severe fragmentation and attrition in multiple heat storage cycles, which can accelerate the elutriation of some fine particles from the reactor. It is necessary to mold CaO-based materials to enhance mechanical strength. In this work, CaO honeycombs prepared by extrusion molding were selected as the molding materials for heat storage. The thermochemical… Show more

“…A variety of TCES materials have been previously studied, including metallic hydrides, , hydroxides, carbonates, and metal oxide materials. , The metal oxide materials are compatible with high-temperature power cycles and are operable in an open loop system, eliminating the reactant gas storage needed for the other systems . Mn 3 O 4 /Mn 2 O 3 was one of the earliest proposed metal oxide TCES systems because of its high reduction temperatures and its low cost and toxicity .…”
