The purpose of research to develop the scientific and technological bases for the creation of a safe transportation and storage of hydrogen-combined system based on the hydride technology, which ensures its high dynamic performance. Research methods and instruments. Methods of mathematical modeling, system analysis, physical modeling. Theoretical and practical results:The maximum value of the power system combined efficiency based on hydrogen hydride technology reaches 8.5% for metal hydride materials at a temperature T = 280 ... 290 K and a specific enthalpy of hydride Н = 30 ... 40 kJ / (mol Н2 ) are founded. The values of specific capacity utilization of the combined power system based on hydrogen hydride technologies expand the powers of the hydrogen expansion engine Pt = 1 ... 350 at the hydrogen inlet temperature T2 = 350 ... 500 K, the inlet pressure P2 = 0,5 ... 15 MPa, with account the real properties of hydrogen are founded. Regeneration mechanical thermal energy can improve heat recovery efficiency of the combined power systems based on hydrogen hydride technology with low speed engine on 3 and 14%, respectively. The method of calculation of the hydrogen expansion machine, account the real properties of hydrogen are developed, the values of the coefficient takes with account the difference between the hydrogen gas from the ideal settings options - imperfection coefficient are founded. Novelty.The scientific and technological basis for the creation of the safe transportation and storage of hydrogen combined system based technologies hydride are developed.
