Proposal of high performance SOFC combined power generation system with carbon dioxide recovery

Techno-economic assessment of biogas-fed CHP hybrid systems in a real wastewater treatment plant

“…It is predicted that the system would become profitable within three to six years. Inui et al [11] proposed a combination of SOFC and closed cycle magneto hydrodynamic (MHD)/noble gas turbine with carbon dioxide recovery. It is reported that the overall thermal efficiency of the system using methane as the fuel could be 63.66% (HHV) or 70.64% (LHV).…”

Full load synthesis/design optimization of a hybrid SOFC–GT power plant

“…Hybrid power plants based on SOFCs are expected to reach values of net electrical efficiencies higher than 70% [2][3][4][5]. According to most researchers, the best way to use a SOFC in a hybrid power plant is to introduce the cell into a traditional Brayton cycle based on the gas turbine (GT) technology [6][7][8][9][10]. In fact, the usual temperature of streams exiting a SOFC is perfectly suitable for the turbine inlet temperature (TIT) required by state-of-the-art-turbomachinery [4].…”

“…In fact, the usual temperature of streams exiting a SOFC is perfectly suitable for the turbine inlet temperature (TIT) required by state-of-the-art-turbomachinery [4]. A great number of possible layouts for hybrid SOFC-GT plants have been proposed in the literature, including combinations of SOFC stacks, heat exchangers, compressors, GTs, pre-reformers, mixers, heat recovery steam generators, and combustors in different arrangements [1][2][3][4][5][6][7][8][9][10]. The performance of these plants has been investigated using a number of different techniques [11][12][13][14][15][16][17].…”

05/02256 Analysis and optimization of a solid oxide fuel cell and intercooled gas turbine (SOFC-ICGT) hybrid cycle

“…A fossil fuel based hybrid SOFC/GT system with liquefaction recovery of carbon dioxide was proposed by Inui et al [5]. Results showed that the total thermal efficiency of the system using natural gas as the fuel reached 70.64% (LHV).…”
