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.

Zero-carbon, hydrogen-based power technology offers the most promising long-term solution for a secure and sustainable energy infrastructure. With contributions from the world’s leading technical experts in the field, Hydrogen Storage Technology: Materials and Applications presents a broad yet unified account of the various materials science, physics, and engineering aspects involved in storing hydrogen gas so that it can be used to provide power. The book helps you understand advanced hydrogen storage materials and how to build systems around them. Accessible to nonscientists, the first chapter explains how a hydrogen-based energy carrier and storage infrastructure is required to address fuel resource and political insecurities as well as global climate change. The second chapter describes high-efficiency hydrogen conversion devices, including internal combustion engines and fuel cells, for producing power and electricity. The book then dives into the state of the art in hydrogen storage technology. It covers recent hydrogen storage materials research and hydrogen storage methods, with an emphasis on solid-state techniques. It also reviews codes and standards and explores engineering approaches for creating zero-emission, hydrogen-fueled power systems. Collecting recent results from around the globe, this book gets you up to date on the latest hydrogen-based technology for mitigating energy and environmental risks. It provides a deep science and engineering-based description of hydrogen storage materials and clearly explains how the materials are engineered for zero-emission, carbon-free power systems.

This book provides a comprehensive introduction to numerical modeling of size effects in metal plasticity. The main classes of strain gradient plasticity formulations are described and efficiently implemented in the context of the finite element method. A robust numerical framework is presented and employed to investigate the role of strain gradients on structural integrity assessment. The results obtained reveal the need of incorporating the influence on geometrically necessary dislocations in the modeling of various damage mechanisms. Large gradients of plastic strain increase dislocation density, promoting strain hardening and elevating crack tip stresses. This stress elevation is quantified under both infinitesimal and finite deformation theories, rationalizing the experimental observation of cleavage fracture in the presence of significant plastic flow. Gradient-enhanced modeling of crack growth resistance, hydrogen diffusion and environmentally assisted cracking highlighted the relevance of an appropriate characterization of the mechanical response at the small scales involved in crack tip deformation. Particularly promising predictions are attained in the field of hydrogen embrittlement. The research has been conducted at the Universities of Cambridge, Oviedo, Luxembourg, and the Technical University of Denmark, in a collaborative effort to understand, model and optimize the mechanical response of engineering materials.
