ABSTRACT

The amount of pollution in the environment has gotten much worse as people have used more conventional fuels and released more pollution into the air. This has led to a search for clean and energy-efficient sources. The main factors to be considered are emissions and sustainability for future uses. Hydrogen is a strong contender in this arena since it is available in abundance and can be obtained through the electrolysis of water or digestion of hydrocarbons. Hydrogen is already being used in refineries, but for power generation, its usage has not been analyzed. Hydrogen can play a major role as an energy-efficient fuel in gas turbines. This chapter focuses on the performance analysis of a gas turbine power plant system built based on the first and second laws of thermodynamics. Analysis results indicate that amalgamating hydrogen and natural gas can benefit the system, and increasing the concentration of said hydrogen will positively impact the system. The effect of steam injection along with hydrogen has also been investigated, and the effect of using blended fuel and steam injection has also been analyzed and discussed. Thermodynamic analyses have been performed on the system, and the individual components, energy degradation, and efficiency have been evaluated. Energy degradation has been noticed to be the highest at the combustor, and, consequently, the efficiency is the lowest, with an average value of 55%–56%. The air compressor efficiency has been observed to be 94.14%, and, hence, the energy degradation in the air combustor is the least. The addition of hydrogen and steam to natural gas has increased the work 184output of the system by an average of 10%, depending on the proportion of hydrogen and steam used. The results of all the investigative analysis for all the operating conditions will be scrutinized in the forthcoming sections.
