3.1.1.7 hydrogen sensors

Hydrogen sensors as the critical "safety gatekeepers" that make the hydrogen flight physically and legally possible. While renewable hydrogen is a decarbonised fuel, its physical properties—extremely small molecular size, high diffusivity, and wide flammability range—make it prone to leaks that are invisible and odorless to humans. Modern sensors—particularly fiber-optic or metal-oxide types—provide the sub-second response times needed to monitor storage tanks, fuel lines, and propulsion pods. By enabling real-time leak detection and optimizing fuel cell purge cycles, these sensors ensure that hydrogen is used safely with maximum efficiency and minimum waste
