Gas infrastructure - Consequences of hydrogen in the gas infrastructure and identification of related standardisation need in the scope of CEN/TC 234

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.

Infrastruktura za plin - Posledice zaradi vodika v infrastrukturi za plin in ugotavljanje s tem povezanih potreb po standardizaciji na področju CEN/TC 234

Ta dokument je oblikovan kot priprava na prihodnjo standardizacijo in vsebuje smernice o vplivu vbrizgavanja vodika v infrastrukturo za plin od točke vnosa plina v kopensko
plinovodno omrežje do točke vstopnega priključka plinskih naprav.
Poleg tega opredeljuje pričakovane potrebe po reviziji obstoječih standardov CEN/TC 243
ter potrebo po nadaljnjih novih standardizacijskih dokumentih.
Na podlagi razpoložljivih študij, poročil in raziskav preučuje učinke na vsak del infrastrukture za plin v okviru delovnih skupin CEN/TC 234 od 1 do vključno 12. Zaradi več omejitev pri različnih koncentracijah vodika so vplivi določeni.
Za nekatere posebne vplive so pred standardizacijo potrebne raziskave.
Po dogovoru se v tem tehničnem poročilu obravnava vbrizgavanje čistega vodika, torej
brez sestavin v sledovih.
Informacije iz tega poročila so namenjene opredelitvi delovnega programa CEN/TC 234 za zajetje H2NG glede na področje uporabe CEN/TC 234 in njegovih delovnih skupin.
OPOMBA: Napredek na področju vodika bo potekal postopoma. Načeloma se bo to odražalo v postopku standardizacije v CEN/TC 234.
