Methane emissions

MEEM DSO

The "Development of an Accurate and Consistent Method for Methane Emission Estimation from the Gas Distribution Grid" project – or MEEM DSO for short – is aimed to develop a pan-European method to estimate gas grid methane emissions.  

Phases I and II of the project are now finished, and the final documents are available (see below).  

Main results of the project:  

  • An Excel model was developed, which includes all relevant equations and assumptions to support national or company emission estimates. 
  • MEEM is as accurate as possible with reasonable effort, enabling a consistent pan-European application.   
  • MEEM provides the potential for estimation with different levels of detail. 
  • Some challenging input parameters have been identified. Those parameters are currently estimated by expert assumptions from the group and should be validated in future follow-up research.  
  • Not all relevant input parameters are available in every country, the need for further measurements, updating of statistics, etc. has been identified.  

Methane emission quantification for transmission

Developing standardized methods of quantification of methane emissions from natural gas transmission systems requires easy to use and reliable tools for detection and measurement.

This project, led by the Polish company Gaz System, has for objective to choose the best available methods and devices for fugitive methane emissions detection and for Transmission System Operators and to perform tests of selected devices. A laboratory and field test programme will lead to the preparation of guidelines on methods for the assessment of fugitive emissions.​

The results of the project are expected for September 2020.

Quantifying underground leakages from (gas) pipelines

This project is a follow up of the MEEM DSO work, with the objective to validate the MEEM technique.  Led by Kiwa, the project partners aim to develop an approach for a European set of measurements of underground leakages, to be used in a methane emission evaluation method.​

The current set of measurements and the measurement method are being analysed, and the model assumptions will be validated by a test program of suctions measurement in Apeldoorn.

The results of the project are expected for January 2020.
