Poweredwith Fuel CellsLarger Aircraft(TBD)A Possible Timeline to Electric AviationElectrification&Hydrogen Technologies in Airports8Potential Impact on the Aviation DemandElectric aviation promises lower OPEX to flight operators.This could make point-to-point air mobility more accessible.General aviation facilities could become local transportation hubs for communities and see their capacity better utilized.Commercial service airports will accommodate more small commuter aircraft with STOL and VTOL capabilities.The novelty of electric aviation,the uncertainty around certification,and the lack of visibility on the future demand does not make it easy for planners&decision makers.Source:Eve Air MobilitySource:Zero AviaElectrification&Hydrogen Technologies in Airports9Opportunities&Challenges for Airports&Communities Electric aircraft are significantly quieter&cleaner than ICU-powered aircraft.Hub airports are becoming intermodal nodes.Mobility-as-a-service(MaaS)can enable a better integration of these modes.With AAM,smaller aviation facilities may become local mobility hubs.Supply chains are needed to meet power requirements&deliver new fuels.On-airport power generation and microgrid can help address these needs.Airports can increase energy resilience and community resilience.Electrification&Hydrogen

Risk:Unusual propulsion systems&lower noise increase risk on the ramp.Current Conditions&Trends:Over 100 e-aircraft projects with atypical config.(ACRP RR 236).Assessment:Risk should be assessed for each type or novel configuration.Potential Mitigation:Joint training sessions with the ramp community.Specific configurations may warrant visual aids(e.g.,markings).Navigating Operational Safety at Aviation Facilities“Most Wanted”:Atypical Configurations!Electrification&Hydrogen Technologies in Airports13Overall Risk:Battery fire/runaway or leak/explosion of hydrogen tank following a high-energy safety occurrence(e.g.,runway excursion).Current Conditions&Trends:Airliners already carry powerful batteries(e.g.,A350,787).Large aviation hydrogen tanks&pods are novel(even per other transportation industry standards).Assessment and Mitigation:Batteries/hydrogen tanks and pods,by design,should not increase the severity of such occurrences(assuming reasonable scenarios)and should be able to withstand some of them(e.g.,runway excursions).Navigating Operational Safety at Aviation Facilities“Most Wanted”:Accident Increases in Severity!Electrification&Hydrogen Technologies in Airports14Navigating Operational Safety at Aviation Facilities“Most Wanted”:Hydrogen Storage&DistributionOverall Risk:H2and hydrogen carriers would be new gases/fluids at airports to be stored,transported,and processedinducing new hazards.Current Conditions&Trends:Safety standards exist for their safe storage and handling in other industries/non-aviation contexts.Assessment and Potential Mitigation:The supply chains for aviation hydrogen are to be developed.Firefighting standards already exist for hydrogen technologies.NFPA guidance on fueling systems to be

236).Once e-aircraft will start being adopted by flight operators:aircraft/airport compatibility studies.Need for an industry playbook providing guidance on compatibility studies What about an“EACG”or“VACG”?26Planning for eAircraft at AirportsElectrification&Hydrogen Technologies in Airports27Policy Considerations:Impact on Fuel Revenues Aviation fuel taxes in Colorado:AviationFuel Excise Tax on aviation gasoline(6per gallon)&fuel(4 per gallon)with exemptions for air carriers.AviationFuel Sales Tax on aviation jet fuel used in turbo-propeller or jet engine aircraft.Special Taxation Districts:RTD(Regl.Transportation District)and RTA(Rural Transportation Authority)sales tax.Flowage Fees:Aviation fuel or gasoline can be subject to a fuel flowage(in-plane)fee imposed by the airport.During FY 2019-2020,$26.4 million of state aviation fuel tax revenues were collected.These tax revenues support,develop,and maintain the Colorado aviation system.Battery-electric and hydrogen-electric aircraft will not use conventional aviation fuels.Hybrid-electric aircraft will use less fuels than conventional aircraft.Food for thought:What will be the impact of electric aviation implementation on fuel revenues over time?How can this loss of revenue be offset?Should electric aircraft pay the difference?Or should electric aviation be incentivized?Should emergingaviation“energyvectors”(electricityand hydrogen)be taxed?Electrification&Hydrogen Technologies in Airports28Policy Considerations:UtilitiesState Laws and Regulations on Additional Fees on Utilities from Facility OwnersState Laws and Regulations on Electric SubmeteringPolicies should articulate the purpose of electric metering and allow for billing aviation tenants and users.Should direct aircraft recharge be allowed in hangars?Who will pay to facilitate this in terms of airport electric infrastructure?How should it be regulated(if applicable)?Is there any conflict with other policies such as grant assurances?The electric aircraft infrastructure is not eligible for most existing funding programs.Should new funding mechanisms be introduced?Where do we draw the line between transmission,storage,and charging infrastructure?What does electrification mean to airports,their community,and local governments?Electrification&Hydrogen Technologies in Airports29Paving the Way for
