Question 3: Comment on the green house gas emissions from your chosen gas turbine. Are there alternatives to make the engine more environment friendly by reducing gases such as SOx, NOx, CO2? Is hydrogen a viable fuel for gas turbines? Use existing academic literature to justify your answer. Also, if the output of the turbojet engine is used for electricity generation, how does it compare against the electricity price in your region assuming the cost of generation has to be covered. Make and state any assumptions made related to conversion efficiency of output power to electricity.
