Abstract

Blending ammonia with hydrogen has the potential of replacing conventional hydrocarbon fuels to reduce carbon emissions. However, the uncertainties of determining safe, stable, and efficient operating conditions remain a great challenge. Furthermore, although control technologies have been in the scope of interest for gas turbine manufacturers, those are not yet specialized for NH3–H2/air gas turbines. Therefore, this paper identifies the cycle performance of an NH3–H2/air gas turbine in comparison to a CH4/air gas turbine, thus highlighting the operating conditions in which the NH3–H2/air gas turbines show higher performance compared to the CH4/air gas turbines. The results have been obtained by developing a LabVIEW code which has also been utilized to serve as a control code for the NH3–H2/air and CH4/air gas turbines. The system identification stage of calibrating the controller has been achieved for both gas turbines by determining the system's sensitivities, thus providing an accurate calibration of the controlling parameters.
