In a decarbonized society, hydrogen is attracting attention as an energy carrier. There are several forms of hydrogen transportation and storage, including liquefied hydrogen, ammonia, methylcyclohexane, and compressed hydrogen, each of which has its advantages and disadvantages, so it is expected that hydrogen will be used in a form appropriate to the method of use. Of these, attention is...
Angle globe valves have been traditionally used in all cryogenic systems. The energy sector is transitioning towards environmentally sustainable technological facilities. Hydrogen represents a key value chain within this sector's focus. Nevertheless, the expansion of these plants presents certain inherent techno-economic challenges.
Ball valves can offer significant advantages to this...
Hydrogen, as a promising alternative energy carrier, has garnered significant attention. Liquid hydrogen (LH₂) exhibits a high density of 70.9 kg/m³, approximately 1.8 times that of hydrogen compressed at 70 MPa. Its high energy density, efficient transport characteristics, and ability to be stored and transported at low pressures make LH₂ an attractive solution for large-scale commercial...
Liquid hydrogen (LH2), known for its exceptionally high energy density and suitability for long-distance transport, is expected to play a pivotal role in the future of hydrogen energy storage and distribution. Central to this transition are port-based liquid hydrogen receiving terminals, which facilitate the seamless loading and unloading of transport vessels. These terminals integrate...
Liquid hydrogen is considered as one of the most promising carriers for large-scale hydrogen storage and transport. However, boil-off losses that occur during the transfer of liquid hydrogen from the trailer to storage at refueling stations pose a significant challenge to the efficiency and cost-effectiveness of these processes. Therefore, the design of the liquid hydrogen transfer system is...
Metal sealing joints are widely used in cryogenic fluid storage and transportation systems, where their sealing performance is critical under extreme low-temperature conditions. In cryogenic environments, changes in material properties can lead to uneven stress distribution at the contact interface, thereby affecting the sealing effectiveness. This study first investigates the variations in...
Hydrogen engines, compared to traditional gas engines, offer higher energy density and combustion efficiency. These advantages not only significantly enhance the propulsion performance of aircraft but also extend their range, presenting substantial potential for applications in the aviation sector. As a crucial component of hydrogen engine systems, the design and performance of liquid hydrogen...
