Aviation does not use that much energy. In fact if you look at it from pure energy point of view it would be very easy to generate the energy used by all aviation in the world by wind and solar. The problem with aviation is that it is hard to store energy for the actual planes. Since everything on a plane must be light, then the energy per weight (i.e., energy density) is crucial, and fossil fuels thus far have unparalleled energy density. So the solution is to make some kind of fuel that is similar to fossil fuels but is carbon neutral. What Rolls Royce is suggesting is that their nuclear plants will be perfect to power the factories that make this green fuel. But of course that is not true. Any grid connected generator can power these factories including renewables that are already much cheaper and safer than nuclear.
