Feasibility of the use of gas phase inhibition of hydrogen embrittlement in gas transmission pipelines carrying hydrogen

R&D Focus Areas:
Hydrogen embrittlement, Pipeline materials and performance

Lead Organisation:
University of Queensland

Funding:
Future Fuels CRC

Status:
Active

Start date:
February 2022

Project summary description:
This research will provide critical knowledge regarding the inhibition of hydrogen embrittlement (HE) by small amounts of added gases (O₂, CH₄, CO, CO₂). If 100% inhibition of HE was practical, then the mechanical behaviour of the pipeline steel for a hydrogen carrying pipeline would be exactly the same as that of a gas transmission pipeline with no hydrogen and the operating characteristics would remain the same as at the present time, regardless of the hydrogen content of the gas inside the gas transmission pipeline.
