Nippon Steel Corporation, Kobe Steel, Ltd., JFE Steel Corporation, and ClassNK play roles as the lead organizations.
This program aims to evaluate the material reliability essential for ensuring the long-term integrity of infrastructure and cargo/fuel tanks for decarbonized energy carriers such as liquefied hydrogen and ammonia as well as structures for liquefied and high-pressure CO2 in carbon capture and storage (CCS) projects. Through these efforts, the initiative seeks to accelerate the development of energy infrastructure for a carbon-neutral society, address domestic demand, and enhance international competitiveness.
As society transitions to carbon neutrality, energy infrastructure is shifting significantly from fossil fuels to new systems utilizing hydrogen and ammonia. This includes liquefied hydrogen tanks, ammonia tanks, CO2 tanks, and high-pressure CO2 pipelines, all of which require material reliability evaluations to ensure long-term safety and economic viability. The program will establish material selection criteria, post-weld heat treatment omission standards, and fracture prevention criteria to optimize infrastructure construction costs and promote international standardization that contributes to a sustainable energy society.
