The EU-funded DEMOSOFC project (www.demosofc.eu) aims to demonstrate the technical and economic feasibility of operating a 174 kWe SOFC in a wastewater treatment plant (WWTP). The fuel for the three SOFC modules (3x58 kWe) is biogas, which is available on-site from the anaerobic digestion of sludge collected from the treated wastewater. A heat-recovery loop allows to recover useful thermal energy from the hot SOFC exhaust gases (90-100 kWth), transferred through a water loop to the sludge.
The integrated biogas-SOFC plant includes three main units: 1) the biogas clean-up and compression section; 2) the three SOFC power modules, and 3) the heat recovery loop. Main advantages of the proposed layout is the net electric efficiency of the SOFC, which is in the range 53-55%, and the near-zero emissions in terms of NOx, SOx, VOC, PM.
The talk will present the results from the first year of operation of the DEMOSOFC system, by showing results in terms of plant electrical production and thermal recovery, integration with the existing plant and loads coverage, performance of the biogas purification unit. The data analysis will lead to first evaluations in terms of criticalities and advantages of biogas-fed SOFC in industrial plants. Furthermore, economic and business perspective will be presented for the proposed plant concept.
