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.
