Jan)
30. The representative from OICA introduced GRPE-85-28 and GRPE-85-41 on the addition of hydrogen (H2) as a fuel for internal combustion engines in UN Regulation No. 49. The representative from Germany sought clarifications on how Ugas factors were calculated in the case of H2. The representative from the EC added that the activity was held in common between OICA and the EC, also aiming at capturing potential decarbonization benefits to be included in the European VECTO tool. The representative from the EC, from the Joint Research Center (JRC), added that a validation exercise with OEMs was on-going, and close collaboration with OEMs was needed as the technology was not available on the market at the present time. He added final results were expected by the end of 2022. The representative from the Netherlands was supportive of the intention of the proposal and asked for some editorials corrections to be included (for example on the need to separate gaseous from liquified H2 in some instances).
31. The representative from OICA agreed the text was still in progress and informed GRPE that an update will be provided at the next GRPE session if a final proposal was not prepared on time for adoption by GRPE.
39. The representative from OICA introduced GRPE-85-25 proposing to add hydrogen fuel and associated specifications in UN Regulation No. 85. The representative from AAPC requested more information about the time when market fuel specifications would be determined, whether at type approval or at the time of the test. The representative from OICA clarified that fuel specifications would be determined at the time of the test.
40. The representative from the EC asked whether it should be Grade I or Grade II hydrogen as specified in GRPE-85-28; moreover, he informed GRPE that there is no reference to ISO 14687 in UN Regulation No. 154 that already covers hydrogen. The Chair proposed to resume the discussions on this item at the next session of GRPE. GRPE supported that proposal.

66. The representative from CITA introduced GRPE-85-30 and GRPE-85-31 presenting the main outcomes of a report on emissions tampering using an urea emulator installed in an Euro VI A heavy truck. The representative from OICA stated that they fully oppose the sale and use of emulators, which is bad for the reputation of car manufacturers; He called for a holistic picture to be considered to mitigate the potential for tampering, highlighting that increased stringency during PTI tests might not be sufficient, with some actors proposing to temporarily revert the tampering to pass PTI tests. The representative from CITA agreed and supported the statement from the representative from OICA, and insisted that tampering is a technical and also behavioural issue, and recalled that inspection and approval performed in isolation were not effective to fully prevent tampering.
67. The representative from the EC called for the existing provision on anti-tampering to be effectively enforced, inviting countries to forbid the sale and use of such emulators. The representative from OICA gave the example of the Swiss law which seemed effective with high penalties and strong enforcement.
68. The Co-Chair from the IWG on PTI called for more expertise needed in the IWG on PTI and suggested to create a task force between GRPE and the IWG on PTI to initiate activities on the issue. The Chair highlighted the need for more collaboration between type approval, certification and PTI, and supported the proposal for the Co-Chair from the IWG on PTI to put together ideas towards the creation of a task force during the next session of GRPE.
