| Objectives | The desired result is the development of new best practice for lowering methane emissions during planned venting activities on the NTS. Expected Benefits: The programme will provide a comprehensive set of experimental and design information relating to the behaviour of large scale ANG natural gas capture. The results will confirm whether ANG is a viable natural gas capture technology and will provide valuable design information for the assessment of suitable utilisation technologies for the captured gas. The delivery of the ANG programme will provide National Grid with a fundamental building block towards a venting capture and fugitive emissions road map giving the company the opportunity of employing a holistic natural gas capture strategy across the network. |

| Abstract | Planned venting can arise from a number of sources around the network, including venting at compressor sites and pipeline decommissioning for repair, replacement or modification. Planned venting at compressor sites is monitored and recorded through the on-line control system. For 2011/12, this was reported as 2984 tonnes of natural gas. For pipeline decommissioning current best practice employed by the Pipeline Maintenance Centre (PMC) involves transfer of gas from the decommissioned section to an active section by means of a compressor but this is only feasible until the decommissioned section pressure reaches 7 bar. At this pressure the Portable Recompression Equipment operation cannot increase the pressure sufficiently to transfer the gas to the active section. So the final operation during decommissioning is to then vent the remaining gas. To improve the environmental performance of final stages of the decommissioning process several options are available including:
