Enhancing safety of liquid and vaporised hydrogen transfer technologies in public areas for mobile applications

缺少与移动的应用（卡车、船舶、固定罐的加注）低温氢转移技术有关的国际标准，经验有限或根本不存在。ELVHYS旨在通过提出创新的安全战略，包括选择有效的安全屏障和危险分区战略，为移动的应用提供内在更安全和高效的低温氢技术和协议的指示，这些都是详细风险分析的结果。这是通过应用一个跨学科的方法和进行实验，理论和数值研究的低温氢转移程序和可能出现的现象，从一件含氢设备的遏制损失。将对以下方面进行独特的调查：（一）选定的移动的应用的低温氢转移操作;（二）设备和材料对液氢（LH 2）转移和事故根源的反应;以及（三）释放、燃烧和爆炸现象。将首次利用一些合作伙伴的内部数据库对液氢转移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有价值的信息。此外，液化空气合作伙伴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，这些数据将超越几年来获得的低温氢转移知识。通过这种方式，可以为制定国际标准提供关键投入，为低温氢转移技术制定安全和优化的程序和准则。ELVHYS的成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、准则和标准的制定。

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.
