Summary

Story summary

The aviation industry is pursuing three main technologies—hydrogen, electric propulsion, and sustainable aviation fuels (SAF)—to decarbonize air travel.
Hydrogen offers a long-term zero-emission solution but faces storage and infrastructure challenges.
Electric propulsion is efficient but limited by battery energy density, so it suits mostly short-range flights.
Hybrid-electric systems blend conventional engines with electric motors to reduce emissions during the transition.
