Abstract

The optimization of biogas production facilities represents a critical component in advancing sustainable energy strategies globally. This study investigates the relationships between biogas composition and electricity generation through comprehensive analysis of 10 months of operational data (August 2023 - June 2024) from a full-scale biogas plant. Data encompassing hourly measurements of methane (CH₄), carbon dioxide (CO₂), and oxygen (O₂) concentrations, alongside active energy generation values, were systematically analyzed. Monthly averages revealed CH₄ concentrations ranging from 44.20% to 54.45%, CO₂ from 33.49% to 38.34%, and power output from 3.25 to 5.30 MW. Statistical analysis demonstrated weak correlations between gas composition and electrical output (r = -0.15 for CH₄, p > 0.05), suggesting that operational parameters significantly influence performance beyond compositional factors. Descriptive statistics indicated mean CH₄ concentration of 48.12 ± 2.85%, CO₂ of 35.34 ± 1.43%, and average power generation of 4.43 ± 0.79 MW. This study proposes eight evidence-based optimization strategies encompassing substrate management, process monitoring, additive integration, emission control, and advanced technologies, with potential to increase energy efficiency by 10-30%. The findings underscore the necessity of holistic operational optimization rather than sole reliance on gas composition for enhancing biogas plant performance and advancing bioenergy sustainability objectives.
