Ultralight tanks for liquid hydrogen allows you to create superliners.
The main advantages of liquid hydrogen as an aviation fuel — high power density and low weight compared to aviation kerosene — are offset by the significant weight of gas fuel tanks.
For example, if we take the total weight of a tank filled with liquid hydrogen, then up to 9 kg of “shell” will fall on a kilogram of fuel. If aircraft designers manage to solve this problem, they will have the opportunity to create airliners flying four times farther than modern jet aircraft.
