As of May 19, 2025, Nippon Steel Corporation announced that 16 more organizations, including University of Tokyo, Kobe Steel, ClassNK, JFE Steel Corporation, JERA Co., and Tokyo Gas Network, among others, have jointly established a Social Collaboration Program entitled “Materials for Future Energy Infrastructure Trust (MEIT) to elucidate and standardize the material reliability of energy infrastructure to support a carbon-neutral society. [1] The research commenced on the 1st of May 2025. Kobe Steel, JFE Steel Corporation, and ClassNK play lead roles. The program aims to evaluate the material reliability essential for ensuring the long-term integrity of infrastructure and cargo or fuel tanks for decarbonized energy carriers like liquefied hydrogen, ammonia, and liquefied and high-pressure CO2 in carbon capture and storage (CCS) projects. The program will establish material selection criteria, post-weld heat treatment omission standards and fracture prevention criteria to optimize construction costs and promote international standardization that contributes to a sustainable energy society.
