Sustainable aviation fuel, or SAF, is a type of alternative jet fuel that can curb carbon emissions by up to 80%. The main reason for the slow adoption is that it’s still more expensive – between 1.5 to 6 times pricier than regular jet fuel. Boeing is not out of the race either, but doesn’t see a hydrogen long-haul plane as around the corner. On medium- and long-haul flights, we don’t see it as a direct source of propulsion until 2040. We would need to see magnitude-order changes [in batteries] for us to consider those for long-haul flights.
