First of all, it should be pointed out that at the climate protection conferences and half-hearted efforts, neither politicians nor the media landscape seriously addressed this chapter. One can see with great interest at the forthcoming climate conference in Egypt whether this need to use hydrogen as a fuel in existing aircraft will also be on the agenda. Engineers at the engine manufacturer in Munich point to advances in the technology of direct combustion of liquid hydrogen in gas turbines. That would be possible in a few years. The only difficult thing is providing the liquid hydrogen, transporting it and carrying it in tanks on the plane. The engineers concerned assert that the implementation of the new technologies and thus the achievement of the climate targets stands or falls with appropriate financial support at national and European level. This as brief technical information. In any case, this global climate-friendly technology deserves much more public interest. The use of kerosene, which is damaging to the earth, must soon be phased out. Over a hundred years is enough to be exposed to the poisoning of the earth. Airbus aims to be the first aircraft manufacturer to produce a hydrogen-powered passenger aircraft. It is scheduled to go into operation in 2035. The costs for this are in the two billion range. For such a sensible and indispensable investment, it is a must. Summary: In view of the urgency of improving climate protection, this chapter in particular should be given much more priority.
