| Abstract Liquid hydrogen (LH₂) is being explored as a potential pathway toward achieving net-zero aviation emissions by 2050. However, its introduction will require significant redesign of aircraft systems, airport infrastructure, and ground handling procedures. This study presents a theoretical system safety analysis of LH₂-powered aircraft during ground operations, with particular emphasis on refuelling activities. Using System Theoretic Process Analysis (STPA), the research identifies system-level hazards, unsafe control actions, and potential loss scenarios within airport environments transitioning to LH₂ fuelling. The analysis highlights critical vulnerabilities related to communication, equipment integrity, environmental conditions, and human factors. The findings provide proactive safety insights intended to inform future airport design, training frameworks, and infrastructure investment strategies for LH₂ aviation integration. |
