• Abstract:

  The thermochemical water splitting process utilizing the copper-chlorine (Cu-Cl) cycle is recognized as a new method for the production of hydrogen gas, a clean and sustainable energy carrier. This innovative process is characterized by a thermolysis reaction, a complex interaction involving molten salt, a solid reactant, and gaseous oxygen, resulting in the generation of hydrogen gas. The core objective of the present study is to significantly contribute to the advancement and refinement of the thermochemical Cu-Cl cycle for hydrogen production. To realize this goal, a thorough review of the multiphase oxygen generation reactor, an essential component within the Cu-Cl cycle, has been undertaken. This extensive review addresses a wide range of considerations pertinent to the oxygen reactor, encompassing its design and operational characteristics, the unique features of the materials employed, the various factors influencing the reactor’s dimensions, and the critical analyses required for its effective scale-up. Through this work, the study aims to furnish a detailed comprehension of the oxygen reactor’s role within the Cu-Cl cycle, underlining its pivotal importance in the thermochemical generation of hydrogen. Furthermore, this investigation seeks to clarify the essential considerations necessary for the reactor's optimization and scaling, thereby facilitating the enhancement of hydrogen production efficiency within the Cu-Cl cycle framework.
