Production of alternative sources of fuel can be conducted through the use of biomasses derived from large amounts of bio waste products and algae masses. Again use of liquid hydrogen and other cryogenic materials like use of ethane and methane gases in the liquid state is also being recommended for the fuel generation of aircraft engines. Thus the use of considerable amount of biomass and cryogenic liquids for the production of aircraft engine fuel is considered a sustainable means for generation of aircraft fuel. Use of such energy resources are observed to help in reducing the combustion temperature of the engines which in turn led to the production of low or no amounts of carbon dioxide.

Further research is enabled to derive natural gases from both natural bio mass and other synthetic sources with also enhancing the dependence on gases like Ethane derived from natural gases for production of sustainable fuel for aircraft engines (Daggett et al. , 2007, p. 1). Technical and Ethical Feasibility of Efforts in Production of Sustainable Aviation Fuel The current aviation fuel which is used is either the spirit derived from petroleum resources or other gasoline products.

The gasoline products used for aviation fuel is observed to be free of lead content or may be containing lead in very less amounts which helps in rendering less amount of pollutants into the atmosphere. Other recent aviation fuels contain of Jet Fuels of category A and B. The category A Jet Fuel is composed of Lead Free Kerosene Fuel while category B is composed of Kerosene mixed with Naptha. However the Jet A category fuel suffers from a serious back draw for having a very high freezing temperature.

It is observed that the fuel freezes only at a temperature of -40 degree centigrade making it unfit for use in aircrafts (Williams, 2008, p. 544). The determination of technical feasibility of the alternative sources of aircraft fuel can be observed by analysing the different sustainable fuels like fuels derived from synthetic sources and others derived from biomasses. Fuels derived from synthetic sources are considered technically feasible for being free of sulphur emissions and also in helping in the stability of heat of the engines.

Thus such fuels are increasingly recommended for fighter aircrafts. Ethically this fuel resource is also feasible for it helps in the lessening of harmful pollutants like sulphur in the atmosphere making it healthy for the living beings to breathe. However negative impacts can also be studied in regards to the use of synthetic fuels for aircrafts.
