Biogas upgrading and cleaning
High Efficiency and Zero Emissions Biogas-to-Power: Solid Oxide Fuel Cells and Advanced Biogas Cleaning
Short Introductive summary
This study explores the viability of Solid Oxide Fuel Cells (SOFCs) for small to large-scale biogas plants, emphasizing their superior energy conversion efficiency (55%) and lower emissions. Biogas-SOFC systems, crucial for on-site heat and electricity generation, face challenges in contaminants like hydrogen sulfide. A mathematical adsorption model is used for a techno-economic assessment, evaluating biogas cleaning impact on the levelized cost of electricity (LCOE) for 3-kW and 100-kW SOFC applications. Results indicate Norit-RGM3 activated carbon’s efficacy for H2S removal. For a 3-kW plant, cleaning unit costs significantly affect LCOE, while for a 100-kW plant, SOFC pricing dominates, making the lead-and-lag layout economically favorable. Overall, biogas-SOFC systems demonstrate substantial potential for efficient and sustainable renewable energy generation at various scales.
