ELVHYS - Enhancing safety of Liquid and Vaporised HYdrogen transfer technologies in public areas for mobile applicationS

目前缺乏与移动应用（卡车、船舶、固定储罐的充氢）的低温氢转移技术相关的国际标准，经验有限或根本不存在。ELVHYS旨在通过提出创新的安全策略，包括选择有效的安全屏障和危险分区策略，为移动应用中固有的更安全、更高效的低温氢技术和协议提供指示，这些策略是详细风险分析的结果。这是通过应用跨学科方法，并对低温氢转移程序和可能因含氢设备的安全壳丢失而产生的现象进行实验、理论和数值研究来实现的。将进行以下方面的独特研究：(i)选定移动应用的低温氢转移操作，（ii）设备和材料对液氢（LH2）转移和事件根源的响应，以及（iii）释放，燃烧和爆炸现象。通过利用一些联盟合作伙伴的内部数据库，将首次对LH2传输设备的故障频率进行研究，这些数据库包含过去几十年收集的宝贵信息。此外，液化空气合作伙伴还将分享正在开发的创新安全屏障（例如紧急释放装置）的关键和独家数据，以及几年来在低温氢气转移方面获得的知识。通过这种方式，可以通过为低温氢转移技术创建安全和优化的程序和指南，为制定国际标准提供关键投入。ELVHYS的结果将有助于实现清洁氢JU SRIA的许多目标，例如提高安全水平，支持氢技术和应用的法规规范和标准的制定。

International standards related to cryogenic hydrogen transferring technologies for mobile applications (filling of truck, ship, stationary tanks) are missing, and the experience is limited or non-existent. ELVHYS aims to provide indications on inherently safer and efficient cryogenic hydrogen technologies and protocols in mobile applications by proposing innovative safety strategies including selection of effective safety barriers and hazard zoning strategies, which are the results of a detailed risk analysis. This is carried out by applying an inter-disciplinary approach and conducting experimental, theoretical, and numerical studies both on the cryogenic hydrogen transferring procedures and on the phenomena that may arise from the loss of containment of a piece of equipment containing hydrogen. Unique investigations on (i) cryogenic hydrogen transferring operations for selected mobile applications, (ii) equipment and materials response to liquid hydrogen (LH2) transfer and incident roots, as well as (iii) releases, combustion and explosion phenomena will be pursued. For the first time, a study on the frequency of failure of LH2 transferring equipment will be carried out by exploiting the internal databases of some of the consortium partners which contain valuable information collected in the last decades. In addition, critical and exclusive data on innovative safety barriers (e.g. emergency release device) under development will be shared by Air Liquide partner, beyond knowledge on cryogenic hydrogen transfer gained in several years. In this fashion, critical inputs can be provided for the development of international standards by creating safe and optimised procedures and guidelines for cryogenic hydrogen transferring technologies. The results of ELVHYS will contribute to many objectives of the Clean Hydrogen JU SRIA such as increase the level of safety and support the development of regulations codes and standards for hydrogen technologies and applications.
