No single solution to decarbonise aviation

Aircraft of varying sizes and in varying regions are likely to use different technologies to decarbonise, making regulation challenging

Hydrogen technologies will form one part of a range of strategies to decarbonise the aviation industry, making regulation and infrastructure an especially complicated issue for airline and airport operators, according to industry figures speaking at a recent summit hosted by hydrogen and electric aircraft developer ZeroAvia. Aircraft of varying sizes and on varying routes are likely to use different types of technology to decarbonise, with lighter aircraft using battery and fuel-cell propulsion systems, and heavier aircraft using liquid hydrogen or sustainable aviation fuel (SAF). Biofuels are currently the only option for SAF— which is the only technology that can work with existing aircraf
