Hydrogen's Flight Path: Fuel Cells, Turbines, and the Economics of Clean Aviation
10 Oct 2025 | 
Aviation is shifting from Jet A to four fuel systems: electricity, hydrogen (fuel cell and combustion), SAF, and petroleum. Fuel cells suit short-haul aircraft; hydrogen combustion may power long-range jets. SAF bridges legacy fleets. Hydrogen costs - $5-$7/kg today, possibly $2/kg by 2040 - impact ticket prices and infrastructure decisions. Airport authorities, airlines, and governments will share deployment costs. Each fuel has distinct environmental pros and cons shaping aviation's net-zero future.
