At the recent International Conference on Advancements in Sustainable Engineering, held in Crete, Greece, from 28 September to 3 October 2025, Dr. Injun Yang from University of Strathclyde presented groundbreaking research titled “Hydrogen Dispersion and Safety Assessment of Vent Mast Releases on an LH₂ Carrier in the LH2CRAFT Project.”
The presentation focused on the dispersion behavior of hydrogen released through vent masts on liquefied hydrogen (LH₂) carriers, combining computational fluid dynamics (CFD) simulations and analytical modeling to evaluate potential safety implications. Dr. Yang highlighted how varying operational and environmental conditions influence hydrogen cloud formation, dilution patterns, and interactions with the surrounding atmosphere.
This research proposed a refined methodology for defining hazardous zones and establishing safe separation distances, providing critical insights for the safety assessment and design of LH₂ carriers. The work represents a key contribution to the LH2CRAFT Project’s mission to improve the safety and feasibility of hydrogen-fueled maritime transport.
Conducted by Dr. Injun Yang and Dr. Hayoung Jang from University of Strathclyde, this study advances the development of a comprehensive safety framework for future LH₂ ship operations and design standards — supporting the transition to cleaner, safer, and more sustainable marine energy systems.
