Airport installation including a plurality of dihydrogen storage tanks

A method of providing hydrogen to one or more aircraft at an airport installation, the method comprising:

• providing an installation including a first storage tank with dihydrogen at a first pressure range, a second storage tank with dihydrogen at a first pressure range, a third storage tank with dihydrogen at a first pressure range, and a fourth storage tank with dihydrogen at a fourth pressure range, the first pressure ranges of the first storage tank, the second storage tank, the third storage tank, and the fourth storage tank being different from each other;
• and,
• filling a tank of an aircraft with dihydrogen,
• wherein when the first storage tank is at a first degree of filling, the first storage tank is at a saturation pressure in a second range of 1.05 bar to 1.2 bar, the second storage tank is at a second degree of filling such that second storage tank is at a saturation pressure in a second range of 2 bar to 3 bar, the third storage tank is at a third degree of filling such that the third storage tank is at a saturation pressure in a second range of 4 bar to 5 bar, the fourth storage tank is at a fourth degree of filling such that the fourth storage tank is at a saturation pressure higher than 5 bar, such that each storage tank passes successively and in parallel from the first degree of filling with a saturation pressure in the second range of 1.05 bar to 1.2 bar to the second degree of filling with a saturation pressure in the second range of 2 bar to 3 bar to the third degree of filling with a saturation pressure in the second range of 4 bar to 5 bar to the fourth degree of filling with a saturation pressure higher than 5 bar and to the first degree of filling with a saturation pressure in the second range of 1.05 bar to 2 bar.
