“…In addition to the costs associated with hydrogen fuel production and fuel cells, it is critical to assess the material costs, which constitute a significant part of the storage and transportation system's overall expenses, to ensure commercial viability. Similar approaches have been observed in LNG storage systems where efforts have been made to use materials with lower nickel content or to replace them with high-manganese steel [13][14][15][16][17][18][19][20]. While using 316L stainless steel, known for its excellent hydrogen resistance, may be a safe choice for material selection, applying it universally across all hydrogen environments can be inefficient.…”

As the maritime industry’s emphasis on sustainable fuels has increased, liquid hydrogen (LH2) has emerged as a promising alternative due to its high energy density and zero-emission characteristics. While the experience of using natural gas in ships can serve as a basis for the introduction of hydrogen, the different risks associated with the two fuels must also be considered. This review article provides a methodology for selecting suitable metal materials for shipboard LH2 storage and piping systems based on operational requirements. The effects of both liquid and gaseous hydrogen environments on metal materials are first comprehensively reviewed. The minimum requirements for metal materials in liquefied natural gas (LNG) storage systems, as stipulated in the IGC and IGF codes, were used as a baseline to establish minimum requirements for liquid hydrogen. The applicability of austenitic stainless steel, a representative metal material for cryogenic use, to a liquid hydrogen environment according to nickel content was examined. In order to apply liquid hydrogen to the marine environment, the minimum requirements for liquid hydrogen were organized based on the minimum requirements for metal materials in the LNG storage system covered by the IGC and IGF codes. Finally, to expand the material selection criteria for low-temperature cargo and fuel storage facilities at sea, slow strain tensile testing, fatigue life, and fracture toughness considering the hydrogen environment and cryogenic temperature were derived as evaluation items.

“…Due to the growing demand for energy, natural gas has become an important commodity to satisfy this demand [1][2][3][4][5][6]. It is estimated that the LNG demand will grow faster than the gas demand [7], which has led to huge investments in developing floating vessels [2,4].…”

Refrigeration effects lower than − 20°C can be traditionally achieved using a vapor-recompression refrigeration cycle with various refrigerants having their own supply temperatures. In this study, the values contained in the liquefied natural gas (LNG) cold heat have been estimated when more than 30 pure refrigerants are liquefied by exchanging heat with LNG instead of using a vapor-recompression refrigeration cycle. There was a total of 35 selected refrigerants for evaluation of cold heat price contained in LNG, which includes n-butane, propane, propylene, ammonia (NH3), 1,1,1,2-tetrafluoroethane (R-134a), hydrochlorofluorocarbon (R-22) etc. Simulation works have been carried out for each single refrigeration cycle using the Peng-Robinson equation of state in combination with TWU’s alpha function. PRO/II with PROVISION V2021, a steady-state simulation tool from Aveva Company, was used to model the refrigeration cycle and LNG cold heat value estimation. It was concluded that the estimated values of the LNG cold heat were inversely proportional to refrigerant supply temperature since the compressor power is proportionally increasing when the refrigerant supply temperature is lower and vice versa.
