This document establishes the functional requirements for stations for the injection of biomethane, substitute natural gas (SNG) and hydrogen into gas transmission and distribution systems operated with gases (natural gas, biomethane, SNG, hydrogen, gas mixtures) in accordance with European technical rules that ensure the interoperability of systems. Figure 1 describes the general approach including all the relevant functions that can be installed in different configurations. The injection of Hydrogen is covered separately in EN 17928-3:2024. This document also applies to refeeding stations that feed such gases back into upstream gas supply networks; see Figure 2. This document represents the state of the art at the time of its preparation. This document does not apply to injection stations operating prior to the publication of this document. This document specifies common basic principles for gas infrastructure. Users of this document are expected to be aware that more detailed national standards and/or codes of practice can exist in the CEN member countries. This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles. In the event of terms of additional requirements in national legislation/regulation than in this document, CEN/TR 13737 (all parts) illustrates these terms. CEN/TR 13737 (all parts) gives: — legislation/regulations applicable in a member state; — if appropriate, more restrictive national requirements; — a national contact point for the latest information.
