Hydrogen fuel is a promising alternative to fossil fuels because of its numerous performance advantages and clean combustion. However, there are economic and technical concerns which need to be addressed for its application to be feasible. This study aims to present the performance analysis of industrial gas turbines fueled with hydrogen. Default fuels of hydrogen and natural gas provided in the GasTurb performance simulation software were adopted and consequently simulated to ascertain the performances of the various fuels under investigation in the industrial gas turbine model. When the plots of natural gas and hydrogen were compared for clean condition, the thermal efficiency for the engine run on natural gas was 0.363 as against 0.374 for hydrogen fuel. This translates to 2.9 % increase in thermal efficiency for hydrogen fuel. Also, when the clean and degraded conditions were compared for natural gas, it shows that thermal efficiency reduced from 0.363 to 0.352. Time to rupture for the engine run on natural gas is 77,652 hours as against 222,050 hours for hydrogen.
