Feasibility of the Use of Gas Phase Inhibition of Hydrogen Embrittlement in Gas Transmission Pipelines Carrying Hydrogen: A Review

Abstract

This review paper introduces a research project that seeks to quantify oxygen inhibition of gaseous hydrogen embrittlement with possible application for gas transmission pipelines transporting hydrogen. And it summarizes the compelling laboratory evidence that oxygen may inhibit gaseous hydrogen embrittlement. Quantification of oxygen inhibition of gaseous hydrogen embrittlement is needed to allow evaluation of this approach to the inhibition of hydrogen embrittlement in gas transmission pipelines. The experimental approach is explained as the quantification of the amount of hydrogen entering the steel from gas mixtures containing hydrogen using a purpose-built gas phase permeation cell.
