Fukui Seisakusho Co., Ltd. (FUKUI) and ClassNK have signed a Memorandum of Understanding concerning a joint study on a safety relief valve for a cargo tank of liquefied hydrogen carriers at the “Gastech2023” held in Singapore.
To combat global warming, attention is growing towards hydrogen as an energy source that does not emit CO2 at the point of use. The realization of a hydrogen-based society necessitates the establishment of a secure and efficient supply chain that distributes hydrogen produced in an environmentally friendly manner to consumption areas. As the measure to transport large volumes of hydrogen over long distances efficiently, carrying liquefied hydrogen via ships are considered promising, spurring ongoing advancements in related technologies.
In order to ensure safety in the transport of liquefied hydrogen, the development of safety relief valves that can handle hydrogen’s characteristics including extremely low temperatures, ease of leakage, and hydrogen embrittlement, which leads to a decrease in material strength and toughness, is necessary. Appropriate safety standards are also required. As part of the efforts to establish key technologies for hydrogen transport, FUKUI, and ClassNK have agreed to jointly conduct a study for the installation of safety relief valves for cargo tanks of liquefied hydrogen carriers on actual ships.
