The ELVHYS project addresses a critical gap in international standards related to liquid and cryogenic hydrogen transferring technologies for mobile applications such as filling trucks, ships, and stationary tanks. Currently, there is limited or non-existent experience in this area, posing significant challenges for safety and efficiency in hydrogen transfer operations.
The overarching objective of ELVHYS is to develop inherently safer and more efficient liquid and cryogenic hydrogen technologies and protocols for mobile applications. This objective is pursued through innovative safety strategies and engineering solutions, including the selection of effective safety barriers and hazard zoning strategies. The project utilizes an interdisciplinary approach, combining experimental, theoretical, and numerical studies to address various aspects of liquid and cryogenic hydrogen transfer.
Key objectives of the ELVHYS project include:
• Providing a comprehensive report on the state of the art of cryogenic hydrogen transfer operations, including knowledge gaps, international standards, regulatory challenges, and safety strategies.
• Identifying hazards and incident scenarios associated with cryogenic hydrogen transferring operations and prioritizing areas with the highest risk and least knowledge.
• Conducting experimental campaigns to investigate cryogenic hydrogen transfer operations and associated phenomena, such as releases, fires, and explosions.
• Developing and validating numerical simulation models for cryogenic hydrogen transfer operations and mitigation techniques.
• Proposing innovative safety strategies and engineering solutions based on experimental and modeling results.
• Disseminating project results to the fuel cell and hydrogen community, including authorities, standard development organizations, and other stakeholders.
• Contributing to the development of international standards for cryogenic hydrogen transferring technologies.
These objectives are achievable thanks to the expertise and resources of the consortium members, who possess unique experimental facilities, theoretical and numerical research capabilities, and practical experience in hydrogen safety. The project aims to not only fill existing knowledge gaps but also to lay the groundwork for sustainable impact through continued collaboration and dissemination beyond the project duration. By addressing these objectives, ELVHYS seeks to significantly enhance the safety and efficiency of cryogenic hydrogen transferring technologies on a global scale.
