There is no need for registration for any interested participants. You can use the above-mentioned meeting id and password (Microsoft teams) also stated in the attached invitation poster.

This is the first (Part 1/6) 60 minutes duration lecture, within the webinar on Hydrogen storage and transportation: Challenges and Solutions organized by "Advanced Materials and Characterization Research Group", Tata Steel Limited, part of the Tata Group , India.

Tata Steel group is among the top global steel companies with an annual crude steel capacity of 34 million tons per annum. It is one of the world's most geographically-diversified steel producers, with operations and commercial presence across the world.

My webinar/lecture content:

1. What is hydrogen embrittlement?
2. Hydrogen embrittlement mechanisms in steel and their synergy.
3. Hydrogen embrittlement effects on mechanical properties.
4. The problems of hydrogen embrittlement in new and old (aged) oil and gas pipelines transporting hydrogen-gas mixture and 100% hydrogen.
5. How can hydrogen embrittlement be predicted and avoided?
6. Summary about materials, hydrogen transportation in pipelines, hydrogen embrittlement, challenges, safety, and solutions.

Summary of my webinar/lecture:

Blending hydrogen into existing natural gas pipelines and hydrogen transport is now actively considered as part of the decarbonization strategy in Europe, Australia, and the United States. The key impediment is the possibility of hydrogen embrittlement and hydrogen-induced cracking of steel pipelines. This lecture also provides recent results and the current state of the art in understanding the synergistic action and interplay of hydrogen embrittlement mechanisms in steel, experiments, and models. It also summarizes hydrogen transportation in pipelines, hydrogen embrittlement, challenges, safety, and solutions.

Motivation

A selection of suitable materials is critical for the safety of any hydrogen application. Most engineers know that hydrogen embrittlement and other hydrogen-specific damaging mechanisms of various metallic materials represent serious threats. Nevertheless, a handful of people have understood the highly complex physics of hydrogen-materials interactions to predict and prevent hydrogen embrittlement and other hydrogen damage. The deleterious hydrogen effects and provoked degradation of mechanical properties of steel are expressed in diverse forms and often in opposite ways, including both softening and hardening phenomena, depending on three main factors: material, mechanic, and environmental [1-3].?
