Abstract: This newly proposed combined scheme focuses on the thermodynamic examination of the solar energy-powered integrated configuration for producing power, hydrogen, and heating by clean methods. The system embraces a solar tower, a helium-based Brayton cycle, and a hydrogen generation and compression unit. Comprehensive parametric investigations are conducted employing the energetic and energetic performance approaches to determine the plant's performance. The calculation results indicated that the proposed model can generate 1,316 kW of net electricity, 10,424 kW of heating, and 0.01116 kg/s of green hydrogen. Overall, the examined model has 47.44% energy efficiency and 16.72% exergy efficiency.

Keywords: energy; exergy; hydrogen; helium; solar tower.
