Parametric Analysis on Hybrid System of Solid Oxide Fuel Cell and Micro Gas Turbine With CO2 Capture

The solid oxide fuel cell–micro gas turbine hybrid system with CO2 capture seems to be a prospective system with high efficiency and low emissions. Three hybrid systems with/without CO2 capture are designed and simulated based on the IPSEPro simulation platform. The performance on the design point shows that case 2 is a better one, whose system efficiency is 59% and CO2 capture rate is 99%; thus, case 2 is suitable to build a quasi-zero carbon emission plant. However, case 3 is more suitable to rebuild an existing plant. Then the off-design point performance and the effect of the capture rate on the system performance of cases 2 and 3 are investigated. The suggested capture rate for cases 2 and 3 is given based on the result, taking both economic factors and carbon emissions into consideration.
