The National Institute for Materials Science (NIMS) in Tsukuba, Ibaraki Prefecture, Japan, has recently introduced a state-of-the-art facility dedicated to the search for materials suitable for the storage and transportation of liquid hydrogen. This facility is the first in the world to evaluate materials under ultra-low temperatures close to that of liquid nitrogen, adjusting both temperature and pressure simultaneously. The primary goal of this facility is to identify cost-effective and safe materials that can facilitate a hydrogen-powered society in the future. Hydrogen has emerged as a promising next-generation fuel due to its absence of carbon dioxide emissions during combustion. However, challenges arise in storing, transporting, and using hydrogen due to its atoms causing brittleness in materials and the difficulties in handling liquid hydrogen, which requires extremely low temperatures. Japan has established legal standards for materials used with hydrogen, primarily relying on a specific type of stainless steel. The focus is now on reducing costs while ensuring safety to expand the hydrogen economy. The new facility, funded by the government's Green Innovation Fund, was completed at a cost of around 3 billion yen and equipped with four testing devices developed by NIMS and private companies. Experiments at the facility involve analyzing materials filled with liquid hydrogen for durability and breakage susceptibility over various timeframes. By conducting experiments with different metals until fiscal year 2025, researchers aim to build a comprehensive database of materials. This information will be shared with private companies from fiscal year 2026. The ultimate goal is to enhance the range of materials available for the storage and transportation of liquid hydrogen, leading to cost reductions and supporting the realization of a hydrogen society. Yoshinori Ono, a unit leader at NIMS, expressed the aspiration to expand material options for liquid hydrogen storage and transportation while contributing to cost reductions essential for the hydrogen society's success.
