Abstract

The fuel conversion for a stationary gas turbine from conventional LNG to hydrogen is recognized as a key technology for carbon neutrality in power generation. However, the present NO_x reporting method does not properly evaluate NO_x generated from hydrogen combustion. The current standard uses NO_x, which has been corrected to the reference oxygen concentration(15%) after complete extraction of H₂O from the exhaust gas. For a hydrogen combustion, the concentration of H₂O and O₂ in the exhaust gas increases more than that of hydrocarbon fuels, resulting in over-reporting the actual NO_x emission. In this study, under the operating conditions of hydrogen turbines currently being developed, NO_x is calculated to be 39.6% over actual emissions affecting the environment. Therefore, it is very important and urgent to establish a new and appropriate NO_x reporting method to accurately consider the characteristics of hydrogen combustion.
