ISO/TC 197 Plenary Meeting is held in Essen, Germany
Karen Hall, National Hydrogen Association


The 2010 ISO/TC 197 Plenary Meeting was held in conjunction with the World Hydrogen Energy Conference on Sunday, May 16.  There were 44 participants from 10 countries.

Here are the highlights from the meeting.

There are currently twenty participating countries and twelve observing countries in ISO/TC 197.

The Chairman, Randy Dey, is forming an advisory committee on hydrogen storage.  It will include matters relevant to Working Group (WG) 6 and WG11 and coordinate work with Technical Committee (TC) 22 and TC58/SC3. Participating Countries may nominate members.
 

ISO DIS 17268 Hydrogen land vehicle refuelling connection devices, Revision of 1st edition of the International Standard is currently out for comment and voting until June 25. This revision adds a 70 MPa profile and removes the 50MPa profile. The target for the Final Draft International Standard (FDIS) is October 2010.

ISO TS 15869 Gaseous hydrogen and hydrogen blends – land vehicle fuel tanks. The technical specification (TS) was published in February 2009. In order to ensure that this ISO work continues, the work item was registered as a new project on June 29, 2009. An effort to restructure the working group is ongoing. The goal is to reflect a membership that is more directly related to tanks, vehicles, and regulation.  ISO/TC 197 expects names to be released within a month or two and expects to proceed with document development.  The convener will be someone representative of the industry.

DIS ISO 22734-2 Hydrogen generators using water electrolysis process- Part 2: Residential applications, was approved and will be submitted for FDIS later in the year.  The next meeting is anticipated for sometime in the fall. At the end of this work, ISO 22734-1 will be looked at to harmonize terminology and other learnings from 22734-2.

ISO 16110-2 Hydrogen generators using fuel processing technologies — Part 2: Test methods for performance was published on February 15, 2010.

ISO/TS 20100:2008 Gaseous hydrogen — Fuelling stations. The Technical Specification was published in December 2008. WG 11 has been addressing comments in preparation for a Draft International Standard. Task Group 1 is addressing separation distances.  Frederic Barth gave an update that recognized the contributions from Sandia National Laboratories. He indicated the technical issues have been resolved. The US agreed to look into whether this is the case, as the US experts do not believe agreement has been reached on all the issues.

Steven Rouvroy provided the status of Task Group 2 of WG11, which is addressing issues relating to dispensing.  Re-drafting should be complete for Chapter 7 (compression) in June and Chapter 11 (dispensers) in July.

There was a discussion regarding the use of “stand-alone” in the scope of WG11.  Many, perhaps most hydrogen stations are expected to be retrofit into existing stations.  The convener indicated that the current scope would remain for document development but work would begin even before the standard is published to fast track the retrofit provisions.

ISO 14687-2 Hydrogen Fuel —Product Specification — Part 2: Proton exchange membrane (PEM) fuel cell applications for road vehicles.  The WG12 draft International Standard (DIS) is expected by end of year.  A draft (with test methods) is expected by the end of June.                                          

Work on ISO 14687-3 ISO 14687-3 Hydrogen Fuel — Product Specification — Part 3: Proton exchange membrane (PEM) fuel cell applications for stationary appliances by WG14 has started.  A scope change was going to be proposed but has been withdrawn pending further discussion.  There is a concern over the number of grades of hydrogen proposed within the document to cover a range of hydrogen generators and purification systems.

It was agreed that after WG14 sorts out what they need with regard to stationary, a review of the general issue would be conducted with the goal of simplifying the number of hydrogen standards.  All 3 parts of ISO 14687 will be examined once part 2 has advanced.

New Work Items
Germany proposed to re-constitute WG7 and begin revision/update on the technical report for ISO TR 15916: Basic Considerations for Safety of Hydrogen Systems.  The plan is to keep the document as a technical report.

China is planning to submit a New Work Item Proposal for Pressure Swing Absorption (PSA) system requirements.

The next plenary meeting will be held in China (2011).
