The energy vector hydrogen has the potential to support a low carbon economy. However, difficulties with hydrogen distribution and storage currently prevent its widespread use. Therefore, other indirect storage media including methanol and ammonia are currently under consideration. Ammonia is one of these and a carbon-free carrier that has a higher energy density than compressed air. Hence, it is proposed that ammonia, with its established transportation network and high flexibility, could provide a practical next generation system for energy transportation, storage and use for power generation. The gas turbine is a power-generating device which offers the potential benefits through ammonia fueling. Consequently, a gas-turbine combustor that burns NH3 along with other fuels has controlled emissions and combustion properties is greatly desired. This paper reviews the investigation of Ammonia Biodiesel Fuel Blends in Micro Gas Turbine using Simulation and Modeling. The mixing of fuel and air plays a major role in the spray and flame behavior, hence, affects the combustion performance and emissions of the internal mixing of fuel injector. A specific modification of the premix injector nozzle geometry can improve the combustion performance significantly. It is proposed that multi-injector designs be improved, which will have an impact on fuel air mixing, swirling flow, spray characteristics, and combustions. With greater penetration duration and spray area but a smaller spray angle than diesel, the spray forms were found to be dependent on the equivalent ratio or mass flow rate.

Hence, it is proposed that ammonia, with its established transportation network and high flexibility, could provide a practical next generation system for energy transportation, storage and use for power generation. Although ammonia can be used as a fuel, burning of ammonia presents a number of difficulties, including low flammability, significant NOX production, and low radiation intensity.
