The fourth generation of high-temperature reactors holds great promise for large-scale and environmentally friendly hydrogen production, especially when combined with steam methane reforming and carbon dioxide capture processes. However, there has been limited research on the design and economic evaluation of integrated fourth-generation systems and steam methane reforming for nuclear hydrogen production, particularly with the integration of a combined cycle as part of the overall power system.
This study develops and analyzes an advanced system for simultaneous hydrogen and electricity production powered by a high-temperature reactor. The system employs a steam methane reforming process with enhanced carbon capture, along with a combined cycle approach. The modeling of the system is performed from both thermodynamic and economic perspectives using the powerful Aspen Plus software, assessing its thermodynamic performance under various operational conditions.
Additionally, several parametric studies were conducted to identify the factors affecting hydrogen and electricity production. The simulation results indicate that the proposed system achieves an energy efficiency of 73%, with hydrogen and electricity production yields of 16% and 23%, respectively. These findings suggest that the proposed system outperforms previous multi-generational systems studied in the past. Furthermore, the exergy efficiency of the proposed system is calculated to be 69.9%.
