Representative case Studies 83 7.1.6 Scenario 2: Projected Energy Use with an Aggressive Switch to Alternative Fuels In this scenario, the airport wants to explore a what-if scenario with a more aggressive switch to alternative fuels. The following fuel mix is now being analyzed: • Passenger and GA jet aircraft: 90% Jet A, 10% alternative jet fuel • Passenger GSE: 30% green diesel, 30% CNG, 40% electricity • Airport vehicles: 20% gasoline, 10% diesel, 40% biodiesel, 30% electricity The fuel volumes associated with this fuel mix are shown in Table 18.

Representative case Studies 87 7.2.2 Case Study Objective The objective of the case study is to evaluate how the energy mix spreadsheet can be used to help airports do a comprehensive analysis of energy demand as the basis for an energy use strategy. The purpose is to indicate the strengths and limitations of the toolkit and stimulate its usage by other airports. Read the entire page →
