Hydrogen Embrittlement Reduced by Oxygen and Moisture (HEROM)

Project Code: 35410

Start date and planned duration: April 2023, 24 months


  • To understand what data are available concerning the effect of oxygen and moisture on the susceptibility of a wide range of steels to Hydrogen Environmental Embrittlement (HEE).
  • To propose and carry out a number of tests to help increase our understanding.

Project Outline

To perform a literature search and review in order to determine the extent of knowledge already available on the effect of oxygen and moisture on HEE and recommend a suitable testing programme.

Suitable material to be sourced and recommended testing performed.

Benefits to Industry

At present NetZero is proving to be a tremendous driver to the decarbonisation of almost everything in our daily lives. There is huge interest in hydrogen as a carbon-free energy vector and yet there is a large gap in our working knowledge of the use of both existing and new assets in hydrogen. Standards organisations and operators are exploring what existing infrastructure or new systems will be suitable for storage and transmission of hydrogen-rich gases. This project aims to provide knowledge to support this transition.
