A method is provided for producing a tank, in particular a motor vehicle tank, for storing a fuel in a low-temperature state. The tank has an inner tank receiving the fuel, an outer skin surrounding the inner tank and an insulating layer arranged between the inner tank and the outer skin. The method i) introduces fuel into the inner tank, a temperature of 30° C. to 120° C., preferably of 70° C. to 85° C., being obtained by the fuel in the inner tank, and ii) generates negative pressure in an insulating layer arranged between the inner tank and the outer skin.

1. A method for producing a tank for storing fuel in a low-temperature state, the tank having an inner tank receiving the fuel, an outer skin surrounding the inner tank, and an insulating layer arranged between the inner tank and the outer skin, the method comprising the acts of: introducing fuel into the inner tank, a temperature of 30° C. to 120° C. being obtained by the fuel in the inner tank; andgenerating a negative pressure in the insulating layer arranged between the inner tank and the outer skin with a vacuum pump;wherein the act of generating the negative pressure or the acts of introducing the fuel and generating the negative pressure are carried out in a vehicle tank arranged on a vehicle. 2. The method according to claim 1, further comprising the act of: preheating the fuel before the fuel is introduced into the inner tank in order to obtain the temperature of 30° C. to 120° C. 3. The method according to claim 1, further comprising the act of: heating the fuel introduced into the inner tank in the inner tank in order to obtain the temperature of 30° C. to 120° C. 4. The method according to claim 1, wherein the act of generating the negative pressure is carried out to an absolute pressure in the insulating layer of 10−3 mbar to 10−5 mbar. 5. The method according to claim 1, wherein a temperature of the fuel introduced into the inner tank upon introduction is between 0° C. to 70° C. 6. The method according to claim 5, wherein the temperature is between 20° C. to 50° C. 7. The method according to claim 1, wherein the temperature being obtained by the fuel in the inner tank is between 70° C. to 85° C. 8. The method according to claim 1, wherein the vacuum pump is a turbomolecular pump. 9. The method according to claim 1, wherein the acts of introducing the fuel and generating the negative pressure are carried out in accordance with a first filling of fuel into the vehicle tank. 10. The method according to claim 9, wherein the vehicle tank is a cryopressure tank configured to receive hydrogen in a supercritical state as the fuel. 11. The method according to claim 1, wherein the vehicle tank is a cryopressure tank configured to receive hydrogen in a supercritical state as the fuel.
