  "abstract": "Hydrogen is increasingly recognised as a cornerstone of future clean energy systems, yet its large-scale production remains constrained by efficiency and sustainability challenges. Concentrated solar power (CSP) coupled with thermochemical water-splitting cycles offers a promising solution, with the Sulfur–Iodine (S–I) cycle standing out due to its high theoretical efficiency and full water-splitting capability. This study aims to design and assess a solar cavity receiver integrated with the S–I cycle for efficient hydrogen generation. CFD simulations in ANSYS Fluent were employed to evaluate receiver performance, achieving an outlet air temperature of 1405 K at a mass flow rate of 0.00285 kg/s and a thermal efficiency of 80%. The absorbed heat was subsequently coupled with an Aspen Plus model of the S–I cycle. Scaling the system to ten parabolic dish collectors resulted in a hydrogen output of 0.75 kg/h and an overall efficiency of 57.7%. Model validation against published experimental data confirmed the robustness of the approach. These results highlight the potential of optimised cavity receivers in advancing CSP-driven thermochemical hydrogen production.",
