Working Group #11

Gaseous Hydrogen – Service Stations
ISO TS 20100

 
Scope

This international standard specifies the design, operation and maintenance characteristics of stand-alone outdoor public and non-public, and indoor warehouse fueling stations that dispense gaseous hydrogen used as fuel onboard land vehicles of all types.

Residential and home applications to fuel land vehicles are excluded from this technical specification.

The fueling station may comprise, as applicable, the following:

  • Delivery of hydrogen by pipeline, trucked in gaseous and/or liquid hydrogen,
  • On-site hydrogen generation using water electrolysis process or hydrogen generators using fuel processing technologies,
  • Liquid hydrogen storage, pumps and vaporizer,
  • Gaseous hydrogen compression and purification systems
    • Note: When the fueling station comprises an on-site hydrogen generator, a compressor/purifier system is commonly integrated into it.
  • Gaseous hydrogen buffer storage, pre-cooling device
  • Gaseous hydrogen dispensers.
Status Technical Specification published in 2008.

The Working Group is continuing activity to publish an International Standards.

Two Task Groups have been formed.

                   Task Group 1 – safety distances & hazardous area

                   Task Group 2 – dispensing systems & fuelling protocols

 

The scope will temporarily be limited for the upcoming ballot in February or March 2011 of the Draft International Standard. Indoor fueling and operations & maintenance will not be included.

 

In August 2011, ISO/DIS 20100 failed its ballot to move to the Final Draft International Standard phase. The course of action this document will take is unclear at this time.
