HyRRAC brings together hydrogen risk research experts, industry, and enthusiasts in one place to share their findings, experience, and research progress towards risk and reliability of large-scale hydrogen storage plants and systems. Submissions are accepted into the following areas:

This topic covers scientific study of hydrogen dispersion, fire, and explosion.


This topic covers a range of education and workforce development activities, including public education, workforce training, and university programs.


This topic includes sharing insights and lessons learned from conducting failure analysis and incident investigations. Papers will include both scientific approaches to incident investigation and engineering analysis of recent hydrogen incidents or failure analysis. The emphasis is on sharing insights that can help enhance safety and prevent future failures and incidents.


This topic covers data, methods, and analysis involved in planning and optimizing maintenance, operations, and testing activities to improve system reliability and long-term performance.


The purpose of hydrogen codes and standards is to protect people and property from the risks and hazards associated with hydrogen. This topic includes papers in the areas of codes and standards developments, research-based revisions to codes and standards, permitting installations, reviews, gap analysis, and resolution of such gaps.


PHM consists of a variety of mathematical and computational methods used to support data-driven decision-making to increase the safety, availability, and reliability of complex engineering systems. PHM can provide crucial insight into equipment trends and imminent failure, enabling diagnosis, prognosis, reliability prediction, and more. This topic includes papers involving advances in PHM methods, data sources, and novel hydrogen applications.


Quantitative risk assessment (QRA) is a family of methods for identifying and evaluating potential hazards and scenarios, determining the likelihood of hazards and pivotal events occurring, and estimating the consequences of each scenario. The results of QRA are used to improve the safety of hydrogen systems by identifying and addressing the most important hazards, failures, and mitigation opportunities. This topic includes papers involving advances in data and methods for QRA and application of QRA to novel hydrogen problems.


Reliability analysis focused on development of models and data sources to assess and predict component or system reliability and availability, often based on operational data, accelerated testing, or physics of failure models. This topic includes methods for conducting reliability analysis, new data sources, hydrogen component and system reliability models, and more.


Involving stakeholders and engaging communities is a key aspect in the planning, development, and operation of hydrogen facilities. This can help to ensure that the plant is designed and operated in a way that meets the needs of all stakeholders, and that any potential risks are identified and mitigated. This topic includes papers involving engaging different stakeholders, including local residents, businesses, government agencies, environmental groups, and community organizations.


System safety, process safety, and other related methods focused on operational improvements to hydrogen facilities.
