Gas Turbine Power Plant

In this study, a complete economic analysis of integrating different types of fuel cells in Gas Turbine power plants is conducted. The paper investigates the performance of a hybrid system that comprises of a SOFC (Solid-Oxide-Fuel-Cell), a PEMFC (polymer electrolyte membrane fuel Cell), and SOFC-PEMFC which is/are integrated into a Gas Turbine power plant. Detailed modeling, thermodynamic, kinetic, geometric models are developed, implemented and validated for the synthesis/design and operational analysis of the combined hybrid system. The economic analysis is considered to be the basic concepts for thermo-economic optimization of the power plant under investigation, with the aim of finding the optimum set of design/operating parameters. Moreover, one of the aims of this paper is to present a detailed economic analysis of a highly coupled PEMFC-SOFC–GT hybrid plant, paying special attention to the sources of inefficiency and analyzing their variations with respect to changes in their operational parameters.

The possibility of using a Molten Carbonate Fuel Cell (MCFC) to reduce the CO2 emission from Gas Turbine Power Plant (GTPP) is shown. The MCFC is placed after a gas turbine. The main advantages of this solution are: higher total electric power generated by hybrid system and reduced CO2 emission with remained system efficiency. A comparison of three systems: standard GTPP, GT-MCFC, and GT-MCFC with additional heat exchangers is shown. The application of MCFC could reduce CO2 emission of 73% (absolutely) and 77% relative to produced power.

Gas Turbine Power Plant

Large scale electrical power generation faces two serious problems: (i) energy conservation; and (ii) protection of the environment. High temperatures fuel cells have the potential to deal with both problems. The heat rejected by the fuel cell that would otherwise be wasted may be recovered to power a gas turbine in order to improve the energy conversion efficiency as well as power output of the combined fuel cell-gas turbine power plant. The added advantage of this approach would be to reduce thermal loading and the emission of greenhouse gases per MW electrical power generated. Serious research is being carried out worldwide to commercialise the fuel cell nevertheless there is still ample scope for studying the application of high temperature fuel cells in combination with the gas turbine for large scale electrical power generation. This paper presents the results of a parametric study of the fuel cell-gas turbine power plant to generate electricity. The paper should be of considerable interest to the designers and applications engineers working in power generation industry and other public utilities. The authors hope that the paper would lead to a stimulating discussion.
