Abstract:

A solid oxide fuel cell (SOFC) based power generation system generates electricity at a higher efficiency and emits smaller CO2 being compared to the other conventional power generations. Also, the SOFC system emits fewer pollutants such as CO, NOx, SOx, and particulate matter; therefore, we can regard the SOFC power generation as one of the most efficient and clean power generation technologies. Despite the high efficiency and environmental advantages, a further improvement in efficiency is required for the SOFC to be commercially competitive. One effective way of the efficiency improvement is hybrid system integration; that is a synergic combination of SOFC and other power generation units.

When a new idea of hybridization is proposed, it should be comprehensively analyzed in terms of efficiency, economics, and environmental performance; a process simulation and exergy-based analysis can be effectively applied to the analysis.

In this presentation, various concepts of SOFC power generation will be discussed and analyzed, using the results from the exergy-based analysis method. The exergy analysis can identify the location, magnitude, and sources of thermodynamic inefficiencies. Also, the results of a demonstration project of SOFC-engine hybrid system will be introduced and discussed using the results of exergy analysis.

Bio:

Young Duk Lee is an Associate Professor in the Department of Energy Technology at Korea Institute of Energy Technology (KENTECH). Before joining KENTECH, a new energy-oriented university, he has worked for the Korea Institute of Machinery and Materials for sixteen years between 2005 and 2021. From 2002 to 2002, he worked for a home-appliance industry, the Winia Mando Incorporate. He received a B.S. from Yonsei University in 2000, and an M.S. from the Seoul National University in 2002 in Mechanical Engineering. He received his Ph.D. in Energy Engineering from the Technische Universit├Ąt Berlin in Germany in 2015.

His research interests include process simulation, exergy analysis, economic analysis, and life cycle assessment of various energy systems, including fuel cell power generation, CO2-free hydrogen production, oxyfuel combustion gas turbine, and other hybrid energy systems. He is also interested in reactor design and demo-system integration of the proposed novel ideas; he was in charge of a demonstration project of SOFC - engine hybrid power generation system in recent years during working for the KIMM.
