* Explains how to use nuclear process heat for industrial applications, especially process heat for hydrogen production * Illuminates the issue of waste heat in nuclear plants, offering a vision for how it can be used in combined-cycle plants * Undertakes the thermal analysis of intermediate heat exchangers throughout the life cycle, from the design perspective through operational and safety assurance stages This book describes recent technological developments in next generation nuclear reactors that have created renewed interest in nuclear process heat for industrial applications. The author's discussion mirrors the industry's emerging focus on combined cycle Next Generation Nuclear Plants' (NGNP) seemingly natural fit in producing electricity and process heat for hydrogen production. To utilize this process heat, engineers must uncover a thermal device that can transfer the thermal energy from the NGNP to the hydrogen plant in the most performance efficient and cost effective way possible. This book is written around that vital quest, and the author describes the usefulness of the Intermediate Heat Exchanger (IHX) as a possible solution. The option to transfer heat and thermal energy via a single-phase forced convection loop where fluid is mechanically pumped between the heat exchangers at the nuclear and hydrogen plants is presented, and challenges associated with this tactic are discussed. As a second option, heat pipes and thermosyphons, with their ability to transport very large quantities of heat over relatively long distance with small temperature losses, are also examined.
This book combines issues several critical ones in the energy field (low-energy technologies, renewable energies such as the hydrogen economy, and geothermal energy).
Moving towards a more sustainable world requires a complete revolution in the way we manage energy and resources. However, from an academic perspective, this theme is so broad that most educators and researchers tend to focus on just one aspect, and maintaining the broad viewpoint which is necessary for making strategic judgments becomes difficult. Tohoku University addressed this challenge when developing a new education and training program for environmental leaders and brought together the extensive range of expertise available in specific fields into one special course which forms the basis of this book. Now in one volume, both students and educators can be brought up to date on a wide range of critical issues currently being addressed in the field of energy and resources. Chapters on resources include availability (for instance, rare earth metals), extraction and recycling of metals and plastics, and technological solutions to specific waste-disposal problems. In addition, broader strategic issues such as limits to growth and the interaction between the economic system and environmental issues are addressed. Even though each chapter provides topical data and knowledge from disparate and specialized fields, the book is written at a level that is readily understandable by students from all scientific, engineering, and humanities fields.
Energy is crucial to the functioning of any human society and central to understanding East Asia's 'economic miracle'. The region's rapid development over the last few decades has been inherently energy-intensive and the impact on global energy security, climate change and the twenty-first-century global system generally is now very significant and will become more so over foreseeable years and decades to come. The region is already the world's largest energy consumer and greenhouse gas emitter, so establishing cleaner energy systems in East Asia is both a regional and global challenge, and renewable energy has a critically important part to play in meeting it.
This book presents a comprehensive study of renewable energy development in East Asia. It begins by examining renewable energy development in global and historic contexts, and situates East Asia's position in the recent worldwide expansion of renewables. This same approach is applied on sector-specific chapter studies on wind, solar, hydropower, geothermal, ocean (wave and tidal) and bioenergy, and to general trends in renewable energy policy. Governments play a critical role in promoting renewables and their contribution to tackling climate change and other environmental challenges. Christopher M. Dent argues this is particularly relevant to East Asia, where state capacity practice has been increasingly allied to ecological modernisation thinking to form what he calls 'new developmentalism', the principal foundation on which renewables have developed in the region as well as how East Asia's low carbon development is being generally promoted.
Renewable Energy in East Asia will be of huge interest to students and scholars of Asian studies, economics, political economy, energy studies, business, development, international relations and environmental studies. It will also appeal to researchers working on the subject matter in government, business, international organisations, think tanks and civil society organisations.
These lecture notes provide a detailed treatment of the thermal energy storage and transport by conduction in natural and fabricated structures. Thermal energy in two carriers, i.e. phonons and electrons - are explored from first principles. For solid-state transport, a common Landauer framework is used for heat flow. Issues including the quantum of thermal conductance, ballistic interface resistance, and carrier scattering are elucidated. Bulk material properties, such as thermal and electrical conductivity, are derived from particle transport theories, and the effects of spatial confinement on these properties are established.
This book focuses on the fundamental principles and latest research findings in hydrogen energy fields including: hydrogen production, hydrogen storage, fuel cells, hydrogen safety, economics, and the impact on society. Further, the book introduces the latest development trends in practical applications, especially in commercial household fuel cells and commercial fuel cell vehicles in Japan. This book not only helps readers to further their basic knowledge, but also presents the state of the art of hydrogen-energy-related research and development. This work serves as an excellent reference for beginners such as graduate students, as well as a handbook and systematic summary of entire hydrogen-energy systems for scientists and engineers.
