    Experimental verification to developing safety technology for liquefied hydrogen: Project 'STACY' ; Experimental verification to developing safety technology for liquefied hydrogen: Project 'STACY': Global efforts are underway to decarbonize the energy sector. Liquefied (cryogenic) hydrogen (LH2) has high storage density, making it excellent for large-scale storage and transportation, and is expected to play a fundamental role in the hydrogen economy. However, liquid hydrogen has several properties that are potential safety risks.An international collaboration between Germany, France, and Japan is underway in the project 'Towards the Safe Storage and Transport of Cryogenic Hydrogen' (acronym 'STACY'). Project activities are allocated to five work packages to achieve specific goals. This paper reports on the development of hydrogen safety technology using a catalyst (WP3).This technology is called 'Passive Autocatalytic Recombiner: PAR' because it works autonomously without external heating, blowing, or stirring. Liquid hydrogen has the characteristics of extremely low temperature and high energy density, and in the event of a leak, it will expand highly. To achieve the PAR required for these safety measures, the crystal structure of the catalyst was designed from the atomic level, and an actual catalyst was prototyped, and repeated tests were carried out in a large reaction vessel as well as laboratory evaluations. As a countermeasure against the unlikely event of a liquefied hydrogen leakage, progress is being made in the development of catalysts that can oxidize hydrogen even in extremely low temperatures, high expansion, and low-oxygen environments, are resistant to catalyst poisons, and can prevent spontaneous ignition due to heat generation. The catalyst technology uses not only general alumina supports, but also ceria and perovskite-type oxides to control the surface state of precious metals, suppressing hydrogen ignition through multi-stage configuration and showing resistance to contamination from oxygen and carbon monoxide. Furthermore, the mechanism of catalyst poison resistance was elucidated using synchrotron radiation.
