Towards a Reliability Database for Hydrogen Equipment

Reliability databases for hydrogen equipment are essential for risk and reliability assessments of both established and new hydrogen facilities.Existing hydrogen event databases have significant limitations with respect to quantity and quality of data, hence providing limited value for rigorous assessments.There is a lack of standardization in the hydrogen sector when it comes to data collection and analysis.In addition, there seems to be a lack of stakeholder incentives to perform data collection and sharing.In order to obtain high-quality reliability data for hydrogen equipment, we argue that each of these challenges must be addressed in a structured and holistic manner.In particular, a systematic approach for collection and analysis of failure data should be investigated.Looking at the more mature petroleum industry for inspiration (the OREDA project), we propose a similar setup for hydrogen equipment.Hence, we present an adaptation of the OREDA approach to the hydrogen domain.As an example and test case, we explore the equipment type pressure swing adsorber (PSA) used for (blue) hydrogen purification.The PSA example is detailed in terms of equipment structure (i.e. subunits, components and boundary) as well as failure modes and their criticality.
