Airports play a significant role in economic development while presenting considerable energy consumption with demands from various stakeholders. Their important environmental impact can be reduced through an optimised energy system design. In this study, a systematic framework for the generation and comparison of airport energy systems is developed. Mixed integer linear programming and multi-objective optimization are employed to generate different system configurations, which are then compared using multi-criteria analysis. The airport energy demands are estimated based on a simple model for the building and the airfield handling area, using a limited set of parameters available for any airport. First results for Amsterdam Schiphol and five other European hub airports indicate that fully renewable energy systems can be competitive, especially when integrating battery storage for daily energy management. Self-sufficiencies of around 80% can be economically viable, relying on energy systems employing photovoltaic cells, a CO2 network, batteries and grid electricity.
