"Comprehensive technical/scientific assessment programs must be developed and applied to examine the suitability, integrity, and safety of the existing (aged) and new gas pipelines, for both H2 blending and future 100% H2 transport conditions.

However, despite the fact that gaseous H2 transport via existing gas pipelines is a low-cost option for delivering large volumes of H,?there is a serious threat of hydrogen damage, particularly for old-aged gas pipelines with corrosion and other mechanical damages, after future long-term blended or 100% H service".

Technical Committee TC21 Hydrogen Embrittlement and Transport Page

for the latest updates.

Our aim is to bring together top scientists and researchers in the field of hydrogen embrittlement of structural materials, hydrogen technology, and hydrogen transport in order to present the latest achievements, the current state of the art, and the future research framework for a better understanding of hydrogen embrittlement phenomena and complex hydrogen-material interactions.

ESIS Technical Committees work on different aspects of Structural Integrity matters. They are the most important part of the ESIS organization. Their activities are supported by ESIS. The strength of each TC is indicated by the number and scientific quality of Committee members together with their output in terms of reports, recommendations, procedure documents, Special Technical Publications, and the regularity of their technical meetings.

The main objective of ESIS TC21 is to enable open and productive dialogue between all disciplines which study hydrogen embrittlement phenomena from any scientific or technological perspective and which in turn are being transformed by continuous advances in materials science and materials engineering.

The main topics:

Hydrogen-materials interactions

Hydrogen-deformation interactions

Hydrogen embrittlement (HE) mechanisms

Hydrogen embrittlement and fatigue

Hydrogen mapping and novel critical experiments

Materials' mechanical response at different scales

HE-resistant alloys

Multiscale, computational, and atomistic modeling of hydrogen embrittlement

Hydrogen embrittlement prediction and prevention

Oil and gas pipelines transporting hydrogen-gas mixture and 100% hydrogen: HE and

HE-assisted fatigue Hydrogen embrittlement and damage - industrial case studies (HE, HIC, HSC, HTHA,...).
