Accuracy of electronic volume conversion systems when metering blends of hydrogen and natural gas

Abstract

This project focuses on ensuring accurate volume conversion within gas metering processes, as hydrogen is blended into the natural gas network across Great Britain. Accurate measurement is essential for fair billing and maintaining customer trust during the energy transition. The project will study real world metering installations, assess potential errors caused by hydrogen blending, and develop practical mitigation strategies. Findings will inform updates to industry guidance (IGEM/GM/5), supporting regulatory compliance and operational integrity.

This project offers significant opportunities for new learning across the gas industry as hydrogen blending becomes more prevalent. Key areas of learning include:

  • Real World Performance of Metering Systems: Understanding how electronic volume conversion systems behave under varying hydrogen blends and operational conditions.
  • Error Quantification and Impact: Generating evidence on the scale and nature of inaccuracies caused by fixed gas compositions versus live hydrogen correction.
  • Effectiveness of Mitigation Strategies: Evaluating which technical and operational solutions deliver the best balance of accuracy, cost, and practicality.
  • Guidance Development: Informing updates to IGEM/GM/5 and other industry standards with robust, evidence-based recommendations.
  • Stakeholder Engagement Insights: Learning how to effectively collaborate with Meter Asset Managers, GDNs, and regulators to implement changes that support the energy transition.

These insights will not only address immediate challenges but also shape future metering practices, ensuring the GB gas network remains fit for purpose in a low carbon future.
