Stopple-Live trial (Phase 2)

The Stopple technology is a flow stop tool essential for major projects and emergency works across the LTS and NTS gas network. Its capability was tested in 100% hydrogen within a helinite environment, in line with LTS Futures parameters as phase 1. This project focuses on validating flow-stopping technology as an additional deliverable with LTS Futures live hydrogen trial on the Granton to Grangemouth pipeline as a welded tee and hot-tapping operations is already being carried out. The trial will confirm the Stopple train’s effectiveness as a double-block and bleed solution for a 100% hydrogen system which will be available for the UK Gas Network. The findings will provide critical insights into the safe and efficient operation of the hydrogen networks supporting the transition from natural gas to hydrogen.
