Description: Novel CaO-based sorbents doped with alkaline earth carbonates were found to show good performance as high temperature energy storage materials for a thermochemical energy storage system. The sorbents were synthesised using the Pechini method and doped with SrO, BaO and Ca₃Al₂O₆. A barium-doped sorbent retained a carbonation conversion capacity of over 60% over 40 calcination and carbonation cycles, while a strontium-doped sorbent retained a conversion of over 40% after 20 cycles. These high temperature (above 800°C) materials have the potential to be coupled with highly efficient and economically competitive power cycles.
