This study investigates a renewable hydrogen production system based on the bio-steam reforming (BSR) of Biomethane, a promising route for clean fuel generation. The proposed system is driven by solar thermal energy to supply the required reforming heat. A comprehensive energy and exergy (2E) analysis is performed to evaluate the system’s thermodynamic performance. Key parameters such as reforming temperature, steam-to-carbon ratio (S/C), and CO₂/CH₄ molar ratio are varied to assess their impacts on hydrogen yield, energy efficiency, and exergy efficiency. The results indicate that optimal hydrogen production and system efficiency occur at higher temperatures (above 800°C) and S/C ratios around 2.5–3. Increasing the CO₂/CH₄ ratio leads to reduced hydrogen yield due to the dilution effect and thermodynamic limitations. The maximum energy and exergy efficiencies achieved were 52.1% and 41.8%, respectively. The findings highlight the potential of BSR-based systems as sustainable solutions for hydrogen generation with improved thermodynamic performance.
