Performance comparison of three trigeneration systems using organic rankine cycles

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 18 August 2011brFahad A., Al-Sulaiman , Feridun, Hamdullahpur , Ibrahim, DincerbrIn this paper, energetic performance comparison of three trigeneration systems is presented. The systems considered are SOFC-trigeneration, biomass-trigeneration, and solar-trigeneration systems. This study compares the performance of the systems considered when there is only electrical power and the efficiency improvement of these systems when there is trigeneration. Different key output parameters are examined: energy efficiency, net electrical power, electrical to heating and cooling ratios, and (GHG) GHG (greenhouse gas) emissions. This study shows that the SOFC-trigeneration system has the highest electrical efficiency among the three systems. Alternatively, when trigeneration is used, the efficiencies of all three systems considered increase considerably….br Highlights: ► We have compared the energetic performance of three potential trigeneration systems. ► These systems are SOFC, biomass, and solar-trigeneration systems. ► The SOFC-trigeneration system has the highest electrical efficiency. ► The trigeneration efficiencies of the biomass-trigeneration system and solar mode of the solar-trigeneration system are the highest. ► The CO2 emissions per MWh of combined cooling, heating, and power production drop significantly when trigeneration is used.
