    The mandate issued by the European Commission in 2007 invited CEN (the European standardization organization) to draw up standards for gas quality parameters for H-gas that were the broadest possible within reasonable costs. The result was the publication of the standard EN16726 "Gas infrastructure - Quality of gas - Group H" in 2015. Natural gas group L was left out due to the smaller trade volume in Europe. However, this standard neither includes the Wobbe Index nor the Gross Calorific Value, both key combustion parameters of natural gas. The reason for this is that during the drafting of the standard, the different stakeholders involved were not able to reach an agreement on the range of these parameters. No consensus was found due to regional differences (gas composition, installation, service practices) and lack of knowledge about the impact of gas quality variations for a few applications. To solve this lack in the standard, CEN is currently working for an agreement on the Wobbe Index range and on the Wobbe variation rate between all interested stakeholders (a so-called CEN SFGas WG "Pre-normative Study of H-Gas Quality Parameters"). To help this process and with the aim to bring a technical view on issues and remedies, MARCOGAZ (Technical Association of the European Natural Gas Industry) has launched an initiative among its members to identify, collect, and analyze results of current and past investigations related to the influence of natural gas quality on gas applications. This initiative includes the identification of research projects and solutions/technologies on how to deal with the variation in gas quality and its possible impact on the safety, efficiency, and emissions of the applications.
