Many modern energy systems are reliant on the production, transportation, storage, and use of gaseous hydrogen. The safety, durability, performance and economic operation of these systems is challenged by operating-cycle dependent degradation by hydrogen of otherwise high performance materials. This important two-volume work provides a comprehensive and authoritative overview of the latest research into managing hydrogen embrittlement in energy technologies. Volume 2 is divided into three parts, part one looks at the mechanisms of hydrogen interactions with metals including chapters on the adsorption and trap-sensitive diffusion of hydrogen and its impact on deformation and fracture processes. Part two investigates modern methods of modelling hydrogen damage so as to predict material-cracking properties. The book ends with suggested future directions in science and engineering to manage the hydrogen embrittlement of high-performance metals in energy systems. With its distinguished editors and international team of expert contributors, Volume 2 of Gaseous hydrogen embrittlement of materials in energy technologies is an invaluable reference tool for engineers, designers, materials scientists, and solid mechanicians working with safety-critical components fabricated from high performance materials required to operate in severe environments based on hydrogen. Impacted technologies include aerospace, petrochemical refining, gas transmission, power generation and transportation. Summarises the wealth of recent research on understanding and dealing with the safety, durability, performance and economic operation of using gaseous hydrogen at high pressure Chapters review mechanisms of hydrogen embrittlement including absorption, diffusion and trapping of hydrogen in metals Analyses ways of modelling hydrogen-induced damage and assessing service life

Hydrogen embrittlement is the process whereby various metals, particularly high strength steels, become brittle and crack following exposure to hydrogen at high temperatures. The process has increasingly been recognized as a key factor in fatigue and failure of components in the energy sector, including developing technologies using hydrogen as an alternative fuel source. This comprehensive reference summarizes the wealth of recent research on how hydrogen embrittlement affects particular industries, its mechanisms and how it can be predicted to prevent component failure.

Owing to the limited resources of fossil fuels, hydrogen is proposed as an alternative and environment-friendly energy carrier. However, its potential is limited by storage problems, especially for mobile applications. Current technologies, as compressed gas or liquefied hydrogen, comprise severe disadvantages and the storage of hydrogen in lightweight solids could be the solution to this problem. Since the optimal storage mechanism and optimal material have yet to be identified, this first handbook on the topic provides an excellent overview of the most probable candidates, highlighting both their advantages as well as drawbacks. From the contents: ? Physisorption ? Clathrates ? Metal hydrides ? Complex hydrides ? Amides, imides, and mixtures ? Tailoring Reaction Enthalpies ? Borazan ? Aluminum hydride ? Nanoparticles A one-stop reference on all questions concerning hydrogen storage for physical and solid state chemists, materials scientists, chemical engineers, and physicists.

Measuring the hydrogen content in materials is important both for research and for various applications in material and surface sciences, such as hydrogen embrittlement of steel, controlled thermonuclear reaction first wall studies, and changed material properties caused by dissolved hydrogen. Hydrogen is the most difficult atomic species to analyze by traditional methods, but nuclear physics methods are particularly suited for this purpose. President of the Uzbek SSR Academy of Sciences P.K. Khabibullaev and Professor B.G. Skorodumov discuss in this book the characteristics of these methods, such as lower detection limits, selectivity in respect to different isotopes, accuracy, depth resolution and maximum detection depth. Examples of applications that are dealt with include the determination of material humidity, the dating of objects, the study of hydrogen diffusion including non-stationary processes, and the investigation of changes in material properties like superconductivity, plasticity and electrical properties due to contamination by hydrogen.

This book is the first comprehensive treatment of hydrogen embrittlement of metallic materials, mainly of steels. The subject is increasingly important with regard to recent requirements for hydrogen energy equipment. Recent progress in revealing the nature of hydrogen embrittlement is remarkable, and this book provides students and researchers engaging in hydrogen problems with a comprehensive view of hydrogen embrittlement covering basic behaviors of hydrogen in materials and their various manifestations in degradation of mechanical properties. Previous studies are critically reviewed and recent advances including new ideas on the mechanism of embrittlement are presented. Emphases are put on experimental facts, but their meanings rather than phenomenological appearance are given particular attention. Experiments are noted on adopted conditions since the operating mechanism of hydrogen might differ by materials and environments. For theories, assumptions and premises employed are noted so as to examine their versatility. Because of the interdisciplinary nature of the subject, brief descriptions of fundamental ideas are presented when necessary.

Hydrogen offers a promising alternative for supplying clean and sustainable energy to meet increasing demands worldwide. However, materials are key to transforming the technology into a viable industry. Materials for the Hydrogen Economy describes the technical challenges and the current efforts in developing materials possessing the properties required for handling each stage of the hydrogen fuel chain. Thorough coverage offers newcomers as well as experienced engineers and researchers a reliable and fully scalable foundation in this field. This book covers all seven of the current hydrogen production methods, as well as distribution, storage, and utilization technologies, particularly fuel cells. It details the chemical reactions, processes, types of feedstock, and commercial equipment involved in hydrogen production. It also covers methods, membranes, liners, and sensors used for separating, sealing, and purifying hydrogen. Several chapters examine corrosion effects in pipeline steels and other storage and transportation vessels, leading to discussions of hydrogen permeation barriers, barrier coatings, and hydrides for on-board hydrogen storage. The final chapters focus on electrolytes and component materials for solid-oxide fuel cells (SOFCs) and H2/O2 PEM fuel cells. Materials for the Hydrogen Economy provides a broad review of material requirements for handling hydrogen from production to market. It explores the development of these materials alongside essential considerations and issues associated with their deployment.
