    Abstract

    A novel CaO-based sorbent was found to show excellent performance as an energy storage material for a thermochemical energy storage system. The sorbent was synthesised using the Pechini method and doped with hydroxyapatite and calcium aluminate. It retained a carbonation conversion capacity of 84% over 40 calcination and carbonation cycles. The improved performance is ascribed to the prevention of grain growth and sintering by the dopants. The use of a proportion of hydroxyapatite in place of calcium aluminate in doped CaO-based sorbents could save costs due to the low price of hydroxyapatite precursors.
