Hydrogen - Diffusion, Permeability, Hydride Formation and Metallic Embrittlement - Part 1

Broadcast Date: 06 September 2022

A Metallurgical Perspective on Hydrogen Issues

Part I - Containment, Diffusion & Permeability

The growing use of hydrogen in the energy industry sets in motion a myriad of metallurgical issues and problems. The metallurgical community has long been dealing with problems associated with hydrogen interaction with metals; from containment in its liquid state at cryogenic temperatures to its burning as a fuel at high temperatures and everything in between. This two-part webinar series addresses some of the more complex metallurgical issues related to hydrogen.

Part I of this webinar deals with issues associated with cryogenic containment, diffusion, and permeability. A discussion of cryogenic materials selection and processing is presented addressing proper containment of hydrogen at extremely low temperatures. The nature of hydrogen gas is covered with a discussion revolving around the very small and very reactive nature of the hydrogen atom. It can diffuse through any material and permeate its microstructure. You can't stop it, but maybe you can slow it down and control it.
