Meeting rooms are available on 10-12 June 2008 for active Working Groups. These are still under consultation and will be announced when they have been confirmed.

Gaseous Hydrogen - Fuelling Stations
A final report of voting on ISO/DTS 20012, Gaseous hydrogen—Fuelling stations was distributed to national TAG members. The vote passed, with Japan, Sweden, the United Kingdom, and the United States voting against. WG 11 was requested to address comments on this vote. Comments for which consensus was deemed easy to reach are included in the final draft. Other comments will be addressed as WG 11 continues its work towards development of an international standard. A draft was circulated that incorporates the agreed comments, and U.S. TAG members are asked to provide input on errors or omissions no later than March 20 to the US TAG Administrator, Debbie Angerman.

Road Vehicles - Compressed Gaseous Hydrogen (CGH2) And Hydrogen/Methane Blends Fuel System Components
Member countries are asked to vote on a New Work Item Proposal (N391) on Road vehicles—Compressed gaseous hydrogen (CGH2) and hydrogen/methane blends fuel system components. Final vote is due by March 31. Participants are requested. This NWIP is to be approved by both TC 22 and TC 197, and work is envisioned in a joint working group structure.

Hydrides
The ISO/TC 197 Secretariat has announced that the ISO/DIS 16111 Transportable gas storage devices — Hydrogen absorbed in reversible metal hydrides has been approved. The comments received are to be returned to ISO/TC 197 WG 10 for its consideration. ISO/TC 197 WG 10 will be working on a tight schedule to make sure that ISO 16111 will be published in time for the December 2008 meeting of the ECOSOC Committee of experts on the Transport of Dangerous Goods (SCETDG).

Hydrogen Fuel Systems for Land Vehicles
As agreed at the last plenary meeting of ISO/TC 197 in Montecatini Terme, an ad hoc group on vehicular hydrogen fuel systems is being formed under the leadership of the ISO/TC 197 Chair. This ad hoc group will be responsible for preparing a strategy paper on how to move forward with the development of an international standard on hydrogen fuel systems for land vehicles.

Experts interested in joining this ad hoc group are encouraged to contact their national TAG administrator as soon as possible. OEMs, fuel tank manufacturers, components manufacturers and regulators are especially encouraged to participate.

At the same time, ISO/TC 197 is encouraging the P-member countries to share any information (test report, analysis) that would facilitate the work of this ad hoc group.

Hydrogen Fuel Quality
ISO TS 14687-2:2008 Hydrogen fuel—Product specification—Part 2: Proton exchange membrane (PEM) fuel cell applications for road vehicles is now published and available through CGA at www.cganet.com.
