38. The representative of OICA introduced ECE/TRANS/WP.29/GRPE/2024/13 and ECE/TRANS/WP.29/GRPE/2024/14 to amending the 05 and 06 series of amendments to UN Regulation No. 49 to permit the use of hydrogen (H2) in internal combustion engines as fuel. The representative of the EC had some reservations he wanted to clarify before agreeing to the proposals. The representative of Germany underlined the 06 series of amendments to UN Regulation No.49 had a similar testing approach as the European Euro VI regulation, so he did not see any objections to adopt ECE/TRANS/WP.29/GRPE/2024/14. The representative of Italy seconded this remark.

39. Following further consultations, GRPE adopted ECE/TRANS/WP.29/GRPE/2024/13 and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2024 sessions as draft new supplement to the 05 series of amendments to UN Regulation No. 49 (Emissions of compression ignition and positive ignition (LPG and CNG) engines).

40. GRPE adopted ECE/TRANS/WP.29/GRPE/2024/14 and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2024 sessions as draft new supplement to the 06 series of amendments to UN Regulation No. 49 (Emissions of compression ignition and positive ignition (LPG and CNG) engines).

41. The representative of OICA introduced GRPE-90-18. The representative of the EC welcomed the initiative, and remarked that some validation testing were still necessary, for example to measure water content. He praised the clear position of OICA regarding the scope and the engines that would be covered by this proposal and was looking forward to considering a proposal at forthcoming sessions of GRPE.
