This article presents a brief review of the integrated approach to the development of hydrogen fuel in various fuel systems. The authors disclose the notion of optimality of the fuel system and explain the necessity of forming a common ground infrastructure for hydrogen fuel supply of ground and air transport with the use of composite cylinders of the same type and pressure level (up to 70 MPa). Necessity to cool hydrogen gas, which is being pumped into a high-pressure balloon, is shown. Calculation of the nitrogen-hydrogen heat exchanger according to the traditional method in a stationary setting is carried out. A non-stationary mathematical model of the heat state of a heat exchanger is given. Calculation and experimental results of tests of a heat exchanger for cooling hydrogen gas with liquid nitrogen are presented. The estimation of the received results is presented.
