“…Other safety criteria related to the use of hydrogen, for example, in fuel cell vehicles, have been formed in earlier works (Corfu et al, 2007;Brosha et al, 2013). Hydrogen has been used for more than a century in various industries.…”

“…Studies by the University of Miami [28], Ballard Power Systems [29], Defence R&D Canada [30] and SNL [31] have established that mixtures below~8% vol. of H 2 in air are not robust enough to propagate a flame throughout an entire mixture, independent of geometry.…”

Computational fluid dynamics a b s t r a c t The International Energy Agency's Hydrogen Implementing Agreement (IEA HIA) was established in 1977 to pursue collaborative hydrogen research and development and information exchange among its member countries. Information and knowledge dissemination is a key aspect of the work within IEA HIA tasks, and case studies, technical reports and presentations/publications often result from the collaborative efforts. The work conducted in hydrogen safety under Task 31 and its predecessor, Task 19, can positively impact the objectives of national programs even in cases for which a specific task report is not published. The interactions within Task 31 illustrate how technology information and knowledge exchange among participating hydrogen safety experts serve the objectives intended by the IEA HIA.

“…The average concentration is to be calculated as a 3-second rolling average so as to accommodate extremely short, non-hazardous transients that cannot exceed 8 vol% H 2 . This value was deemed acceptable based on an investigation quoted in GTR Number 13 that demonstrated that hydrogen flame propagation will not occur below 8 vol% H 2 [14]. To verify compliance with the discharge requirement, a hydrogen detector with a response time of 300 ms was recommended so as to detect hydrogen pulses up to 8 vol% of one second duration.…”

The United Nations Economic Commission for Europe Global Technical Regulation (GTR) Number 13 (Global Technical Regulation on Hydrogen and Fuel Cell Vehicles) is the defining document regulating safety requirements in hydrogen vehicles, and in particular, fuel cell electric vehicles (FCEVs). GTR Number 13 has been formally adopted and will serve as the basis for the national regulatory standards for FCEV safety in North America (led by the United States), Japan, Korea, and the European Union. The GTR defines safety requirements for these vehicles, including specifications on the allowable hydrogen levels in vehicle enclosures during in-use and post-crash conditions and on the allowable hydrogen emissions levels in vehicle exhaust during certain modes of normal operation. However, in order to be incorporated into national regulations, that is, to be legally binding, methods to verify compliance with the specific requirements must exist. In a collaborative program, the Sensor Laboratories at the National Renewable Energy Laboratory in the United States and the Joint Research Centre, Institute for Energy and Transport in the Netherlands have been evaluating and developing analytical methods that can be used to verify compliance with the hydrogen release requirements as specified in the GTR.
