HYDROGEN JET FLAMES AND HYDROGEN EXPLOSIONS

As an energy carrier, hydrogen plays a crucial role in decarbonization and the future of a low-carbon society, where hydrogen production is one of the most important steps in the hydrogen chain. Hydrogen itself can be produced from different processes, and different colors were used to identify the environmental impact, where green hydrogen has been identified as the best in the future. However, the green hydrogen covers only about 1% of the world's production, even with increasing interest. Therefore, learning more about the green hydrogen production will be essential to reach the goal. In the course of hydrogen production, different technologies will be briefly discussed, and the green hydrogen production via water electrolysis or biomass gasification will be the focus, where the principle, component, process, together with sector coupling, will be discussed, and the state-of-the-art and the potential will be covered. To combine with specific implementation and special interests, one seminar, together with a report, will be arranged. It is expected that after this course, basic knowledge of hydrogen production technologies as well as their state-of-the-art and challenges will be clarified; Specific knowledge on the green hydrogen product from principle to the process will be provided, and the students can propose their ideas on how to promote green hydrogen production.

Hydrogen will play a major role in the transition to a low-carbon society. Still, it also introduces demanding conditions for materials and components across the entire value chain, from production and compression to storage, transport, and end-use. Many of the most critical technical risks in hydrogen systems are materials-related, including loss of ductility and premature fracture, accelerated fatigue, unexpected leakage, seal degradation, corrosion, and performance degradation over time. Understanding these mechanisms is essential for making safe, reliable, and cost-effective engineering decisions. This course offers a practical, engineering-focused introduction to materials in the hydrogen economy, including catalysts in hydrogen production and materials used in hydrogen storage and transportation, as well as their impact on component lifetime and system safety. You will learn how hydrogen enters materials, how it moves (diffusion and permeation), where it accumulates (trapping sites), and how these processes can trigger degradation. A special focus is placed on hydrogen embrittlement in metals, particularly in steels and welded joints, because these materials are widely used in pipelines, pressure vessels, fittings, and structural components. The course also covers non-metallic materials that are crucial for hydrogen infrastructure, including polymers, elastomers, and coatings used in liners, seals, hoses, gaskets, and protective layers. In addition to the fundamental mechanisms, the course connects theory to real engineering choices. You will discuss which materials are suitable under different hydrogen conditions (pressure, temperature, purity, moisture, cycling), what typical failure modes look like, and what mitigation strategies can be used in practice, such as material selection, heat treatment, surface engineering/coatings, design measures, operating-window choices, and inspection/testing approaches. The course also introduces materials challenges in key hydrogen technologies such as electrolysers and storage solutions, highlighting how degradation and compatibility issues influence performance and maintenance needs. You will also discuss hydrogen carriers and their storage and utilization solutions. The teaching format combines short, focused lectures with seminar discussions and an applied assignment. Participants are encouraged to bring examples from their own work or studies (for example, a pipeline material choice, a valve and seal problem, a storage tank concept, or an electrolyser component, chemical and physical storage systems) and use these as case studies during seminars and in the final assignment. By the end of the course, you will have both the conceptual framework and the practical tools needed to evaluate materials risks in hydrogen applications and make better-informed decisions for real systems. What you will be able to do after the course After completing the course, you will be able to: Explain key mechanisms of hydrogen–materials interactions and their consequencesIdentify materials-related risks in hydrogen production, storage, and transportationEvaluate and justify materials choices for hydrogen components and systemsPropose mitigation strategies (design choices, coatings, operating conditions, testing/inspection approaches)  Course structure (March 2–31) 6 lectures: Overview of hydrogen economy and materials, Materials in hydrogen production, Hydrogen materials interaction-core concepts, mechanisms, and engineering implications, Hydrogen Carriers, and materials selection and design2 seminars: discussion of case studies and participant problems/components1 assignment: applied analysis/report linked to a realistic hydrogen application (can be connected to your work/project)   March 2 Lecture-Introduction 10:00-10:45 Farid Akhtar Introduction March 5 Lecture I 09:30-11:00 Valentina Zaccaria hydrogen production and utilization – An overview March 6 Lecture II 10:00-11:30 Farid Akhtar Materials in Hydrogen Infrastrucutre- An Overview March 12 Lecture III 10:00-12:30 Alberto Vomiero/Marshet Sendeku Materials in Hydrogen production and conversion March 17 Lecture IV 10:00-11:30 Farid Akhtar Hydrogen Embrittlement Mechanism and Theory March 19 Seminar I 10:00-12:00 Farid Akhtar Topic I March 23 Lecture V 10:00-11:30 Farid Akhtar Mitigating Hydrogen embrittlement: Materials selection and development March 26 Seminar II 10:00-12:00 Farid Akhtar Topic II March 30 Discussion/White Board 09:30-11:00 Farid Akhtar Sorting Challenges   For whom Engineers and professionals working with hydrogen technologies (or planning hydrogen projects)Master’s students in relevant fields Entry requirements Recommended background in engineering/natural sciences (materials/mechanics/chemistry/physics or equivalent).
