Biogas is a crucial renewable energy source for green hydrogen (H2) production, reducing greenhouse gas emissions and serving as carbon-free carrier with higher specific than traditional fuels. Currently, methane reforming dominates H2 production to meet growing global demand, biogas/landfill (LFG) reform offering promising alternative. This study provides comprehensive simulation-based evaluation of Steam Methane Reforming (SMR) Dry (DMR) biogas/LFG, using Aspen Plus. Simulations were conducted under varying operating conditions, including steam-to-carbon (S/C) SMR monoxide (S/CO) ratios DMR, temperatures, pressures, LFG compositions, optimize yield process efficiency. The comparative showed that attains yields (0.14–0.19 kgH2/Nm3), consumption between 0.048 0.075 MWh/kg H2, especially at increased S/C ratios. DMR produces less (0.104–0.136 kg H2/Nm3) requires inputs (0.072–0.079 H2), making it efficient. Both processes require an additional 1.4–2.1 Nm3 biogas/LFG per feed energy. These findings provide key insights improving biogas-based sustainable energy, future work focusing on techno–economic environmental assessments evaluate its feasibility, scalability, industrial application.
