Green Renewable Energy – Risk Need to Be Tackled in Going Green for Air Transportation

This paper will discuss on issues of using alternative fuel (bio jet fuel) for 50% mixing or replacing current Jet A/ Jet A-1 fuel in relationship towards aircraft fuel systems. Two key issues aviation biofuel; Technical Risk and Quality Risk will be evaluated. Technical risk, such as storage stability for biological growth, thermal stability in relation to fuel system components coking, the outcomes from combustion properties and material compatibility to the engine system and discussions on the level of the trace of contamination like metals or micronutrients. In quality risk, the issues need to be measured: the inconsistency of the products such as the source dependencies, robustness control and fragmented enterprise. These two issues need to be measured in order to create a clear pathway for Air Transport in sustainable manner, where further research towards reliability and sustainability for future aircraft performance and maintenance can be correlated.
