ISO has published a new Technical Specification ISO/TS 19880-1, Gaseous hydrogen — fueling stations — Part 1: General requirements, which is a key document for the building of hydrogen fueling stations worldwide. (Earlier post.) The TS was prepared by ISO/TC 197 WG 24, led by co-conveners Jesse Schneider (BMW) and Guy Dang-Nhu (Air Liquide), along with Nick Hart (ITM Power) as secretary.
The scope of the TS covers the processes from hydrogen production and delivery to compression, storage and fueling of a hydrogen vehicle. It is essentially a safety and performance guideline for hydrogen stations, including the interface to fuel vehicles. The level of safety specified in the TS is similar to the level of safety of stations fueling with conventional fuels.

The TS is the first step towards standardizing hydrogen filling stations. It supersedes the earlier ISO/TS 20100:2008 and is part of a series of standards for the components necessary for a fueling station as shown in the diagram below.
The WG comprises experts from hydrogen suppliers, hydrogen organizations, local and national governments and automakers (OEMs) from North America, Europe and Asia.
WG 24 is already working on the next step—the development of an International Standard (IS) to be published in 2017. The IS will be especially important for the adoption into the EU Alternative Fuels Directive for hydrogen stations in Europe. There are plans to build several hundred stations in Europe by 2020.
ISO/TS 19880-1 is a milestone technical specification that provides general safety and performance guidance for the hydrogen station, as well as specific recommendations regarding for fueling a fuel cell electric vehicle (FCEV). It also provides a means for validation of hydrogen quality at the station. Thus, it is an important basis for the implementation of hydrogen infrastructure for FCEVs worldwide.—Jesse Schneider
