Please note that this deliverable is in the process of approval by the European Commission, and a final version may replace it at a later date.
This deliverable describes gas leakage monitoring and detection methods for gas networks which are
currently used or planned to be used by gas network operators as well as emission measurement methods
for gas networks. There are many methods available for both gas leak detection and emission measurement
for gas networks which can be used for gas networks transporting natural gas and hydrogen mixtures. It is
impossible to choose one optimal method because each method described in this document has its
advantages and disadvantages. The choice of the optimal method for leak detection or emission
measurement depends on the measurement conditions.
