DESCRIPTION

PD CEN/TR 17797:2022


This standard PD CEN/TR 17797:2022 Gas infrastructure - Consequences of hydrogen in the gas infrastructure and identification of related standardisation need in the scope of CEN/TC 234 is classified in these ICS categories:
  • 01.120 Standardization. General rules
  • 75.180.01 Equipment for petroleum and natural gas industries in general
This document is written in preparation of future standardization and provides guidance on the impact of the injection of H2 into the gas infrastructure from the input of gas into the on­shore transmission network up to the inlet connection of gas appliances.  Furthermore, it identifies the expected revision need of the existing CEN/TC 243 standards as well as the need of further new standardisation deliverables.  It examines the effects on each part of the gas infrastructure in the scope of the CEN/TC 234 Working Groups 1 to 12 inclusive, based on available studies, reports and research. Due to several limitations at different hydrogen concentrations, the impacts are specified.  For some specific impact, pre­standardization research is needed.  By convention, for this technical report, the injection of pure hydrogen, i. e. without trace components is considered.  The information from this report is intended to define the CEN/TC 234 work program for the coverage of H2NG in relation to the scope of the CEN/TC 234 and its WGs.  NOTE Progress on hydrogen will develop over time. In principle this will be reflected in the standardisation process in CEN/TC 234.
