The oil and gas industry generates a significant amount of harmful greenhouse gases that cause irreversible environmental impact; this fact is exacerbated by the world’s utter dependence on fossil fuels as a primary energy source and low-efficiency oil and gas operation plants. Integration of solid oxide fuel cells (SOFCs) into natural gas plants can enhance their operational efficiencies and reduce emissions. However, a systematic analysis of the life cycle impacts of SOFC integration in natural gas operations is necessary to quantitatively and comparatively understand the potential benefits. This study presents a systematic cradle-to-grave life cycle assessment (LCA) based on the ISO 14040 and 14044 standards using a planar anode-supported SOFC with a lifespan of ten years and a functional unit of one MW electricity output. The analysis primarily focused on global warming, acidification, eutrophication, and ozone potentials in addition to human health particulate matter and human toxicity potentials. The total global warming potential (GWP) of a 1 MW SOFC for 10 years in Qatar conditions is found to be 2,415,755 kg CO2 eq., and the greenhouse gas (GHG) impact is found to be higher during the operation phase than the manufacturing phase, rating 71% and 29%, respectively.

Syngas Cleaning

This paper reviews the most recent information about the main operations to produce energy from carbonaceous materials, namely biomass and wastes through the integration of gasification, syngas cleaning and solid oxide fuel cells (SOFCs), which have shown to be a good option for combined heat and power (CHP) production, due to high efficiency and low environmental impact. However, some challenges still need to be overcome, mainly when mixed feedstocks with high contents of hazardous contaminants are used, thus syngas cleaning and conditioning is of major importance. Another drawback is SOFC operation, hence new materials especially for the anode has been proposed and tested. An overall process to produce CHP by gasification integration with SOFC is proposed.

Abstract This study analyzed the internal phenomena of solid oxide fuel cells driven by liquefied natural gas. Reforming reactions of liquefied natural gas constituent in the solid oxide fuel cells were examined. First, the performance of solid oxide fuel cells using liquefied natural gas was compared to those using methane as fuel. Liquefied natural gas-driven solid oxide fuel cells outperformed methane-driven solid oxide fuel cells under all current conditions, with a maximum performance difference of approximately 12.8%. Then, the effect of inlet composition ratio on the internal phenomena in the solid oxide fuel cells was examined. The lower the steam-to-carbon ratio, the higher the steam reforming reaction in the cell. By changing the ratio, 7.1% of more hydrogen could be reformed. Finally, the effect of reformer operation on the internal phenomena in the solid oxide fuel cells was examined. Under 0.35 A/cm2, lower pre-reforming rate of reformer enhance the performance of solid oxide fuel cells. At high current density region, however, a higher pre-reforming rate of reforming is more favorable because the reforming reaction is rare in solid oxide fuel cells. This research can provide guidelines for achieving high power output of solid oxide fuel cells with high fuel flexibility.
