Thee Certification andRegulatory Hurdles Facing Hydrogen Fuel Cell Aircraft

Hydrogen fuel cell aircraft are widely requided a key technology for decarbon ing aviation, offering the potential for zero in- filigt carbon emissions and reduced reliance on fossil fuels.

Eun if a hydrogen aircraft accesses type certification, it cannot operate with out an enabling regulatory environment for ground infrastructure, fuel handling, and airport operations. The current regulatory landscape is framented across national and international bogies, creating friction for global operations.
