چکیده :

Power-to-X technologies play a crucial role in shaping the future energy landscape by transforming renewable electricity into valuable fuels and chemicals. This study assesses the techno-economic feasibility of an innovative solar-driven hydrogen production process utilizing the Cu-Cl thermochemical water-splitting cycle, examined through a case study. The green hydrogen production system is initially modeled to define its technical configuration. Next, hourly dynamic simulations are conducted to analyze the system’s annual performance under real-world solar conditions using meteorological data. The findings reveal that the system can achieve competitive hydrogen production costs while benefiting from reduced operating expenses due to lower electricity requirements compared to traditional electrolysis methods. Additionally, surplus electricity generated from the integrated gas turbine and steam Rankine cycles can be sold to the grid, enhancing the system’s overall economic viability. A critical factor in designing a concentrated solar power plant is determining the plant’s optimal design radiation, which is optimized using a multi-objective approach. The proposed system achieves optimal performance at a design direct normal irradiance of 881 W/m². Under these conditions, the production cost of hydrogen is about $5.5/kg.
