Supersonic Airliner A2 hydrogen powered

We've seen a lot of cars powered by alternative energy sources: electric cars, hybrid cars, hydrogen cars on the move. Aviation, being the area is much more responsible, will not hurry with such a radical innovation. Apparently, now come and turn.

Aircraft A2 can move up to 300 passengers from Brussels to Sydney in less than 4:00. It is equipped with engines that work in two modes: a turbojet engine and air-jet accelerator. This means high efficiency and at low speeds and during acceleration in the supersonic range. Correct combination of these two modes allows the model A2 smoothly accelerate from Mach (speed of sound) 2.5 to 5. Installed around the engine cooling system, which includes an additional turbine compressor and preventing excessive overheating.

There are, however, and the unpleasant effect of this development. Company Reaction Engine, created this concept would have to find a way to produce hydrogen on a large industrial scale, without carbon dioxide emissions, not very pleasant for the atmosphere.
