Hydrogen energy, as a kind of high energy density, clean and efficient secondary energy, is considered as an ideal green energy. In hydrogen energy application, large-scale hydrogen production, storage and transportation can significantly reduce the energy consumption and cost of hydrogen market application. The energy consumption and energy efficiency of high-pressure hydrogen and liquid hydrogen storage technologies in sea and land transportation are investigated. The results show that high-pressure hydrogen has certain advantages in short distance transportation, and its energy consumption and cost increase with the increase of transportation distance. When hydrogen is stored and transported at 20MPa, its energy consumption and cost increase obviously with the increase of transportation distance. Hydrogen liquefaction requires high energy consumption but low energy efficiency, and the evaporation loss of hydrogen is accoMPanied by the whole process of liquefaction. Therefore, it is not suitable for cross-sea and long-distance transportation.
