Abstract

There has been increasing interest in using simplified tools for safety assessment of available engineering solutions for hydrogen applications in lieu of significantly more time consuming and expensive tools such as computational fluid dynamics. Currently there are few existing hazard and risk assessment tools that contain models that have been developed and validated for use in small-scale hydrogen applications. However, in the past several years, there has been significant progress in developing and validating deterministic physical or engineering models for hydrogen dispersion, ignition, and flame behavior. In parallel, there has been progress in developing defensible probabilistic models for the occurrence of events such as release and ignition of hydrogen. While models and data are available, using this information is difficult due to a lack of readily available tools for integrating deterministic and probabilistic components into a single analysis framework. This paper discusses early steps initiated within IEA HIA Task 31 Hydrogen Safety in the development of an integrated toolkit for performing hazard assessment and quantitative risk assessment (QRA) on hydrogen transportation technologies and potential directions for extending the toolkit.
