Plans unveiled today show three different options on the table, with 2035 suggested as the entry-into-service:

Option 1: turbofan, 200 passengers, using liquid hydrogen stored in tanks

Option 2: propellors, 100 passengers

Option 3: the blended wing. Creates lots of space for hydrogen tanks

There is big interest in the blended wing concept, given the big fuel savings its promises. KLM is working on a prototype but it& #39;s a radical departure from conventional designs, so the technical/regulatory etc obstacles are mighty

There are also doubts about Airbus& #39; "zero emission" claims already. Hydrogen combustion releases water vapour and NOx, both of which can have climate impacts at altitude. Non-CO2 emissions get little focus, great piece here via @CarbonBrief on them https://www.carbonbrief.org/guest-post-calculating-the-true-climate-impact-of-aviation-emissions?utm_content=buffercca22&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer">https://www.carbonbrief.org/guest-pos...
