The present work summarises the requirements for a Quantitative Risk Assessment (QRA) of a hydrogen facility. This is done within a framework of the recently announced National Hydrogen Strategy in the Republic of Ireland. The proposed framework for risk assessment is based on a probabilistic method called Bayesian networks. This framework is expected to provide permitting authorities with a decision support system and guidance for QRA hydrogen facilities.

Keywords: Quantitative Risk assessment, Hydrogen safety, Bayesian Networks, Hydrogen Economy, Uncertainty Quantification.
