What was the capacity of this A30X? Is this 4 AB CRJ-side, 5 AB (A220), 6AB (A320) or 8AB (A330 size)?
How do you think about the safety of the emergency exit's right in front of the rear mounted engines?
I totally disagree on airbus developing a Battery Electric plane. I think that's a nogo because of safety and energy mass density.
The most I expect to see is hybrid architectures, with more engines. The E-fan-X demonstrator with rolls-royce being the example.
But if CO2 emissions are a problem, it's because often a good supply of CO2 is wasted!
I think CO2 is one of the solutions of our energy problem. Indeed we must reduce our reliance on fossile hydrocarbons. But we can also create hydrocarbons using surplus renewable energy and CO2. In greenhouses CO2 levels are raised to increase crop output.
The next 50 years I expect most aviation will remain relying on combustion, because of the high power, high energy mass and volume density requirements. Besides the high safety and reliability demands.
I expect only small regional planes (<40pax) will be fully electrified. All larger planed and longer range planes will remain using hydrocarbons, but how they are sourced will change. E-Fan X
is a hybrid plane demonstrator replacing one or two of the engines with an electric fan. I expect that when planes are made more hybrid, we'll se the return of tri and quad engine planes.
AFAIK this is also a concept of a hybrid, with a giant APU/ fan generator in the center and 6 electric fans on the U-tale.

And let's make clear that I'm totally against decabonisation. Atomic element 6 is a crucial part of our lives. If you want to stop CO2 emissions, first study what you breath in and what you breath out. And it hypocritical to push for decarbonisation and CFRP, it's decarbonise or CFRP you can't have both.
