Hydrogen may be part of the solution for eliminating aviation CO2 emissions. But even if it is, it will take manufacturers several years to deliver a hydrogen-powered commercial aircraft. Equally, it will take time for airports to prepare to host them, and for the economy to provide the huge quantities of zero-carbon energy needed to make the low-carbon hydrogen. Alejandro will outline a new report from the ATI, produced as part of a strategic partnership with Airports Council International (ACI), on the integration of hydrogen aircraft into the air transport system
