31. The expert from OICA made a presentation (GRSP-54-01) to introduce a draft new UN Regulation on hydrogen and fuel cell vehicles (ECE/TRANS/WP.29/GRSP/2013/22), transposing the UN GTR No. 13 into the 1958 Agreement on the same subject. He also presented GRSP-54-12, introducing some corrections to the proposal and GRSP-54-02 (for information only), highlighting the changes introduced with respect to the UN GTR. The expert from Japan made a presentation (GRSP-54-37) on the main objective of the proposal. He also suggested (GRSP-54-22) a separate UN Regulation, to address liquefied hydrogen storage systems and to allow Contracting Parties to apply impact tests already in use at the national level until the conclusion of Phase 2 of the UN GTR. He finally introduced some corrections (GRSP-54-21) to the text of the proposal. GRSP agreed to resume discussion on this subject at its May 2014 session on the basis of a revised official proposal, voluntarily prepared by the experts from EC and OICA, incorporating comments received by interested parties. GRSP also agreed to keep GRSP-54-21 and GRSP-54-12 in the agenda of the next session for reference only.
