The aviation industry is on the brink of a significant transformation with hydrogen emerging as a frontrunner to replace traditional jet fuel. Airports, essential components of national infrastructure, are urged to prepare for this change by adapting to new forms of propulsion efficiently and securely. Hydrogen's advantages over batteries, such as superior energy-to-weight ratio and space efficiency, make it an attractive option for aircraft and airside support vehicles. However, challenges related to storing and converting hydrogen from liquid to gas form exist, requiring additional infrastructure and staff training. Despite these obstacles, hydrogen vehicles are seen as presenting lower risks than battery-powered vehicles due to safer venting capabilities. Different forms of hydrogen - gray, blue, and green - offer similar benefits and risks, with green hydrogen facing supply challenges. Government initiatives are driving the transition, with a focus on infrastructure development and supply chain sustainability. The aviation industry's shift towards hydrogen marks a pivotal moment in sustainable transport innovation, with airports and governments actively participating in this energy transition.
