Abstract: This presented study aims to create a novel perspective on the use of fusion energy to meet the demands of humanity, designing a thermochemical cycle for the Affordable Robust Compact (ARC) fusion reactor and investigating non-electrical useful outputs, modeling integrated energy systems driven by a fusion reactor. Three different cases are developed and analyzed within the scope of this study. All cases are driven by the Affordable Robust Compact fusion reactor. While Case A includes only the open feedwater Rankine cycle, Case B consists of the three-step magnesium chlorine cycle as well to examine the hydrogen production potential. Finally, Case C includes the Affordable Robust Compact fusion reactor-driven open feedwater Rankine cycle, the three-step magnesium chlorine cycle, and two different desalination units, such as the multi-effect desalination and reverse osmosis to examine the potential of hydrogen and freshwater production. All cases are investigated using energy and exergy approaches. As a result, Case A has the highest overall energy and exergy efficiencies, with 39.86% and 59.68%, respectively. Case B produces 1.49 kg/s of hydrogen, whilst Case C generates 3832.2 tons/h of freshwater and 1.24 kg/s of hydrogen using all thermal energy that comes from the Affordable Robust Compact fusion reactor.
