The article delves into the complexities of transitioning aviation to hydrogen fuel. While hydrogen offers sustainability benefits, it poses challenges such as longer turnaround times and safety requirements due to its high flammability. The GOLIAT project, under Assistant Professor Alexei Sharpanskykh, aims to address these challenges by designing infrastructure, modeling ground operations, and working on safety regulations. Multi-agent system modeling is utilized to optimize logistics and operational efficiency, assisting in the shift to hydrogen-powered planes. Regional airports are key in this transition, with plans for real-life demonstrations as early as 2025. The ultimate goal is to develop certification, standardization, and technology for hydrogen-based airport operations to facilitate global adoption. Alexei envisions a future where airports cater to various fuel technologies, with hydrogen playing a significant role, anticipating the possibility of booking a vacation on a hydrogen aircraft by 2035.
