The Hydrogen Incidents and Accidents Database (HIAD) is a knowledge management platform jointly managed by the Clean Hydrogen Partnership and the European Commission’s Joint Research Centre (JRC). The JRC is responsible for the ongoing maintenance, updates, and continuous enhancement of the platform.
HIAD serves as a comprehensive repository of hydrogen-related unwanted events, gathering information from a wide range of primary and secondary sources, including news reports, inspection reports from public authorities, publicly available databases, and scientific publications. Whenever possible, each entry includes a traceable link to its original source, ensuring transparency and facilitating further investigation.
The database is designed as a valuable resource for safety experts, researchers, educators, students, policymakers, and technology developers working in the hydrogen sector. Its purpose is to support knowledge sharing, safety assessment, and risk management across the hydrogen value chain.
HIAD is not intended to be used to assign blame to individual companies, organisations, or countries involved in specific incidents. Promoting a culture of learning rather than blame is essential to encourage the open sharing of safety-related information. Furthermore, in the absence of established benchmarks, the database should not be used to compare the safety performance of hydrogen technologies with that of other technologies.
All events included in HIAD are reviewed and validated by JRC experts before publication. However, users should note that the quality and completeness of the information ultimately depend on the reliability of the original sources from which the data are derived.
To support the correct interpretation and use of the data, detailed guidance and documentation are available to users of the platform.
Since its inception, HIAD has continuously evolved to improve both the quality and comprehensiveness of its content. The platform's development history, including major updates and enhancements, has been carefully documented and is available for users seeking further information.
