In a recent patent filing dated August 7, 2024, Catagen introduced a system for producing hydrogen from water using a thermochemical cycle, specifically the sulfur-iodine cycle. The patent outlines a reactor equipped with multiple reaction zones, each designated for carrying out specific reactions integral to the thermochemical cycle. Unique to this system is the interconnected fluid circuit that links the reaction zones. This design allows reaction products from one zone to be redirected as reactants for another, ensuring minimal waste and maximized use of resources. Additionally, the generated heat in various reaction zones is repurposed within the system, contributing to…
