Several potential deployment scenarios of high-temperature gas reactor (HTGR) cogeneration systems for the simultaneous production of hydrogen and electricity have been proposed recently. They can operate under different conditions and thereby satisfy different hydrogen and electricity demand scenarios, but their performance must be studied to demonstrate thermodynamic feasibility and economic profitability to attract sufficient investment for their deployment. Therefore, this study uses exergy analysis and exergybased costing analysis methods to analyze HTGR cogeneration system performance thermodynamically and economically over the entire range of potential operating conditions by calculating performance indicators, exergy efficiency, and the specific cost per unit product. Furthermore, three optimized deployment scenarios with high performance for satisfying three different hydrogen demand scenarios are proposed based on the analysis results. The proposed three deployment scenarios show that the HTGR cogeneration system is thermodynamically efficient and economically competitive compared with other hydrogen and electricity generation systems. The feasibility of exergy analysis and exergy-based costing analysis methods for analyzing the HTGR cogeneration system so as to propose optimized deployment scenarios is demonstrated by the obtained findings practically.

“…Each individual section was successfully demonstrated in a glass, quartz, and Teflon lab-scale facility by JRC in Ispra, Italy in the 1980s [72]. Despite the less promising economic calculations and the fact that the H 2 SO 4 and HI decomposition caused severe corrosion problems, improvements to this process have continued at diverse locations, like in the technical University of Aachen in Germany [73], in Japan by JAERI, who developed a pilot test plant [74], and by JAEA, who has operated a closed-loop continuous hydrogen production at a rate of 32 l h 1 for 20 h [75].…”

“…Even though more than 200 thermochemical cycles have been identified for the water splitting, very few of them have progressed beyond theoretical calculations to experimental demonstrations, based on performance requirements like high thermal efficiency of hydrogen production, good matching with the high-temperature heat sources, easy plant operation, and easy scaling up of experimental facilities. The iodine-sulphur (IeS) cycle is the most famous and well-studied version of these cycles which was proposed by General Atomics [7], and it is one of the most promising processes regarding the utilization of nuclear heat sources which can supply heat at temperatures close to 1273 K [8].…”
