Gas Inhibitors for Hydrogen Pipelines - Phase 3

Abstract

The Phase 3 project on gas inhibitors for hydrogen pipelines aims to translate lab-scale findings into practical applications for the UK’s National Transmission System. It focuses on validating the effectiveness of oxygen and alternative inhibitors in mitigating hydrogen embrittlement, addressing unresolved safety and integrity concerns from previous phases, and designing a plan for safe integration into existing infrastructure. The project includes physical demonstration planning, and network design to assess technology implementation.

Phase 3 project will help identify a validating methodology to prove real-world effectiveness of gas-phase inhibitors, particularly oxygen in mitigating hydrogen embrittlement in steel pipelines, which is critical for repurposing the transmission System. It will also generate insights into the safe integration of this technology, develop a testing protocol, and produce a practical framework for inhibitor deployment including supply, injection, and monitoring systems
