Summary

Documents

This project will help to inform the GDNs, and wider industry on the mechanism for potential air ingress into gas-conveying downstream pipework, particularly during periods of isolation (e.g., if a consumer manually shuts their ECV before then going on holiday for a number of weeks). The work will investigate the phenomena/behaviour for pure natural gas, hydrogen blends (20%), and pure hydrogen - to inform a holistic view for all gas scenarios.
The findings will help enable any proactive mitigation measures to be considered and/or implemented in future, to help maximise the safety of consumers in any future scenario and engineer-out any possible risks.


The work is supported by all 4 GDNs, and will collaborate with, and leverage, a preliminary project led by SGN.
