Qualitative risk assessment for future hydrogen-enabled airports

Abstract

Introducing hydrogen infrastructure at airports is a key element in achieving net-zero emission aviation and, at the same time, a major challenge for the aviation industry. The operational and infrastructure enhancements required to support the ground handling of alternative-powered aircraft as well as the deployment of zero-emission ground service equipment will require significant future investment and a clear roadmap for implementation. Adapting the existing operational processes and capability levels at the airport to support hydrogen-powered flight, including refuelling and safety requirements, causes challenges but also opportunities. In addition to presenting an exemplary hydrogen deployment roadmap for a mid-sized airport, the authors present a risk register and airport strategies for managing risks to the roadmap by analysing and prioritising airport requirements.
