Abstract

A viable pathway towards sustainable energy is the creation of hydrogen through thermochemical cycles, which split H2O molecules via high-temperature redox reactions. With particular attention given to the two-step process and strategic doping techniques used to enhance redox performance, this review critically evaluates a variety of thermochemical cycles in terms of the materials used and economic factors. With a maximum H2 production of 2827 μmol g−1, La0.6Sr0.4Mn0.4Fe0.6O3 stands out as the most efficient material among those examined, highlighting the crucial role that the Fe concentration plays in maximizing reactivity. La0.6Ca0.4CoO3 (587 μmol g−1) and La0.8Sr0.2CoO3 (717 μmol g−1) are two other potential perovskites that show good performance but suffer from cycling stability. By carefully evaluating the materials according to their reduction temperatures, economic feasibility, and durability, this review provides a comprehensive roadmap for improving thermochemical water-splitting cycles, paving the way for the efficient and affordable production of green hydrogen.
