Overview
EN 17928-2:2024 - "Gas infrastructure - Injection stations - Part 2: Specific requirements regarding the injection of biomethane" is a CEN standard that supplements EN 17928-1:2024 with functional and safety requirements specific to the injection of biomethane into gas transmission and distribution systems operated with gases of the second gas family (per EN 437). It defines technical safety principles for chemical and physical properties of biomethane, risk controls for inadmissible gas compositions from biogas upgrading, and monitoring/operational expectations for new injection stations (not retroactive to stations operating before publication).
Key Topics
- Scope & applicability
- Applies to new biomethane injection stations into transmission/distribution grids (second gas family); intended to be used alongside national rules.
- Risk assessment
- Mandatory risk analysis for possible inadmissible gas compositions from the upgrading process and other failure modes.
- Protection against underpressure
- Prevention of inadmissible underpressure to avoid air intrusion, explosion hazards and mechanical damage; automatic safe-mode actions when limits are reached.
- Handling inadmissible composition
- Requirement that components upstream of the 3‑way valve are resistant to potential inadmissible gas; safety systems must prevent such gas from reaching downstream network.
- Biomethane quality monitoring
- Composition must comply with EN 16723-1; composition checks and calorific value measurement per EN ISO 6974 (where applicable) based on the station risk assessment.
- Contaminant & hazard controls
- Hydrogen sulfide (H2S): tightness, monitoring and local alarm requirements where workplace limits may be exceeded.
- Biological hazards: referenced to CEN/TR 17238 for bacteria-related considerations.
- Water and hydrocarbon dew point: monitored per downstream operator requirements.
- Odorization
- Biomethane composition and injection must not adversely affect the grid’s odorization strategy; national odorization rules apply.
Applications
Who uses EN 17928-2:2024:
- Gas network operators and distribution/transmission system owners specifying injection interfaces
- Designers and integrators of biomethane injection stations and upgrading plants
- Equipment manufacturers (compressors, valves, analyzers) ensuring material compatibility and monitoring functions
- Safety engineers and consultants performing risk assessments and safety concepts
- Regulators, certification bodies and asset owners aligning installations with CEN guidance and national legislation
Practical benefits include improved safety for grid injection, standardized quality checks, prevention of contaminant entry, and guidance for system-level alarm and shut‑down behavior.
