In Power Generation (PG) Industry, the global Original Equipment Manufacturers (OEMs) are focusing to lower their carbon emissions to reduce the impact of global warming to meet the famous Paris agreement goals and targets. At present approximately 25% of Green House Gases (GHG) are emitted during electricity generation, in that 62% contributed by coal & natural gas power plants [1]. Current Gas Turbines (GTs) burn Natural gas (NG) as primary fuel which contains Carbons, obviously emits CO2 as byproduct. The whole industry is investing time and money to research on reducing CO2 emission close to zero by 2040 and checking the feasibilities of using alternate fuels in power generation. The current study reported here does not consider any design or technology changes required to use H-2 or NH3 as an alternate/blending fuel for GTs but attempts to provide some understandings and directions on cost perspective. The approach of this study is to blend the different types of H-2 or NH3 with NG as fuel, evaluate the life cycle cost of combined cycle power plant and other benefits like decarbonization advantages, etc. As the H-2 or NH3 fuel is classified in different color codes based on the source of production process, the study considered Black/Grey/Blue/Green Hydrogen and Grey/Blue/Green Ammonia types only.PG Industry will focus on availability of Green Hydrogen/Ammonia as the production process does not emit CO2. However, a recent market study points out that Green H-2 and NH3 are costlier than NG fuel. The goal of H-2 or NH3 industry is to reduce the production cost of Green H-2 or NH3 to make cost competitive technologies. This study will provide insights to Gas Turbine OEMs to predict the feasible H-2 or NH3 blend with NG on their engines with the existing technical capabilities by considering the cost benefits and savings based on geographical CO2 penalty rates. Additionally, OEMs will get understandings on H-2 or NH3 fuel selection among different types and can focus to reduce the production cost of green H-2 or NH3 to make as economically feasible alternate fuel in GTs.
