The transition to low-carbon energy systems is accelerating across the globe, with hydrogen emerging as a key component of future energy infrastructure. One of the most promising strategies involves transporting hydrogen blended with natural gas through existing pipeline networks. However, the effects of hydrogen on pipeline materials, particularly its influence on fracture toughness and fatigue crack growth, remain a major technical uncertainty. This paper presents a comprehensive material property database developed to support hydrogen pipeline assessments. The database combines fracture toughness and crack growth rate data obtained through collaborative testing by Sandia National Laboratories and DNV, with experiments conducted under high-pressure hydrogen environments following fracture mechanics standards. These results are integrated with established models from ASME B31.12 and API 579 to enable simulated remaining life assessments under various hydrogen blend scenarios. This work provides a critical foundation for evaluating pipeline integrity and ensuring safe, long-term operation in hydrogen transport applications.
