Within the framework of IEA Hydrogen TCP Task 43-C (Safety Distance Methodologies), Rely’s HSE Design expert Jérôme Hocquet – along with 18 co-authors – conducted a survey to assess the applicable regulations and practical approaches used for defining Safety Distances in Green Hydrogen plants.
Their proposals are outlined in the article “Recommendations for Safety Distances Methodology for Alkaline and PEM Electrolyzers” published in the International Association for Hydrogen Safety (HySafe) journal. They include:
- Proposition of strategies for the necessary harmonization of practices (technical alignment on assumptions such as leak size, effect thresholds, models...);
- Identification of best practices regarding mitigation measures to be included in the design of hydrogen production plants;
- Emphasizing the most impactful scenarios that should be considered when defining safety distances.
Rely is very proud to contribute to this international expert collaboration and remains committed to further enhancing the safety of green hydrogen and Power-to-X plants.
