Introduction: The principle objective of the working group is the production of an IGEM standard covering UK gas quality specification in order to facilitate a change from GS(M)R that reflects the decline in UKCS, the available alternative sources of gas and aligns with the European standard. The standard will set the Wobbe Index (WI) range appropriate for the UK initially examining the extension of the upper range. The specification will also examine the further widening in the lower range and changes to other quality parameters at an appropriate stage as and when the evidence emerges. Alongside this technical review there is a parallel process reviewing the legislative and regulatory case for change.

Objectives:

The objectives of the project are:

• Set up of a core group to drive the production of the standard and ensure appropriate representation from across the industry and supply chain
• Identify and map relevant industry groups and bodies and develop a robust communication process and feedback method
• Identify links and necessary representation for these both in the UK and in the EU.
• Set up of sub groups (where required) which will examine the specific potential effects of a change in GS(M)R on the supply chain, industry, customers and asset owners
• Develop database of current and previous studies into gas quality and order evidence in accessible format. –August 2019 Provide detailed reports of progress on a six-monthly basis – First report due in December 2019/Jan 2020
• Produce final version for publication of the updated standard -December 2020.
• Evaluate, identify and facilitate projects toward future gas quality changes.

Expected Benefits: The success criteria for the project are:

• Database of current and previous studies into gas quality developed
• Production of 6 monthly progress reports

• Agreement and approval of the IGEM standard covering UK gas quality specification in order to facilitate a change from GS(M)R.

• Completion of the review process of the IGEM standard covering UK gas quality specification in order to facilitate a change from GS(M)R.
• To establish a  platform to evaluate future gas quality projects
