Metrology to support standardisation of hydrogen fuel sampling for heavy duty hydrogen transport

氢气可以显著减少运输部门的排放，因为它特别适合作为长途重型（HD）车辆的燃料。为支持欧洲的绿色能源未来，需要进一步标准化重型运输的氢吸收。取样系统和方法已经开发出来，用于轻型（LD）车辆的加氢站（HRS），但缺乏重型运输的技术证据。该项目将提供重型应用氢燃料取样标准化所需的证据。这将包括开发污染物（气态物质和颗粒物质）专用采样系统、验证采样方法的方法、评估采样代表性的准则、不确定性预算、安全考虑和排放协议。这些结果将直接纳入CEN TC 268和ISO TC 197中正在进行的标准化活动。

Hydrogen can significantly contribute to reducing emissions from the transportation sector as it is particularly well suited as a fuel for long haul heavy duty (HD) vehicles. The uptake of hydrogen for heavy duty transport requires further standardisation to support Europe’s green energy future. Sampling systems and methods have already been developed for use at hydrogen refuelling stations (HRS) for light duty (LD) vehicles, however there is a lack of technical evidence for heavy duty transport. This project will deliver the evidence needed for the standardisation of hydrogen fuel sampling for heavy duty applications. This will include the development of dedicated sampling systems for contaminants (gaseous species and particulate matter), methodologies for the validation of sampling methods, guidelines for the evaluation of sampling representativeness, uncertainty budgets, safety considerations and venting protocols. The outputs will be directly fed into ongoing standardisation activities in CEN TC 268 and ISO TC 197.
