Hydrogen Safety highlights physiological, physical, and chemical hazards associated with hydrogen production, storage, distribution, and use systems. It also examines potential accident scenarios that could occur with hydrogen use under certain conditions. The number of potential applications for hydrogen continues to grow-from cooling power station generators to widespread commercial use in hydrogen fuel-cell vehicles and other fuel-cell applications. However, this volatile substance poses unique challenges, including easy leakage, low ignition energy, a wide range of combustible fuel-air mixtures, buoyancy, and its ability to embrittle metals that are required to ensure safe operation. Focused on providing a balanced view of hydrogen safety-one that integrates principles from physical sciences, engineering, management, and social sciences-this book is organized to address questions associated with the hazards of hydrogen and the ensuing risk associated with its industrial and public use. What are the properties of hydrogen that can render it a hazardous substance? How have these hazards historically resulted in undesired incidents? How might these hazards arise in the storage of hydrogen and with its use in vehicular transportation? The authors address issues of inherently safer design, safety management systems, and safety culture. They highlight hydrogen storage facilities -which pose greater hazards because of the increased quantities stored and handled-and the dangers of using hydrogen as a fuel for transport. Presented experiments are included to verify computer simulations with the aid of computational fluid dynamics (CFD) of both gaseous and liquefied hydrogen. The book also provides an overview of the European Commission (EC) Network of Excellence for Hydrogen Safety (HySafe) and presents various case studies associated with hydrogen and constructional materials. It concludes with a brief look at future research requirements and current legal requirements for hydrogen safety.

Scholarly writing on the music of Arvo Part is situated primarily in the fields of musicology, cultural and media studies, and, more recently, in terms of theology/spirituality. Arvo Part: Sounding the Sacred focuses on the representational dimensions of Part's music (including the trope of silence), writing and listening past the fact that its storied effects and affects are carried first and foremost as vibrations through air, impressing themselves on the human body. In response, this ambitiously interdisciplinary volume asks: What of sound and materiality as embodiments of the sacred, as historically specific artifacts, and as elements of creation deeply linked to the human sensorium in Part studies? In taking up these questions, the book "de-Platonizes" Part studies by demystifying the notion of a single "Part sound." It offers innovative, critical analyses of the historical contexts of Part's experimentation, medievalism, and diverse creative work; it re-sounds the acoustic, theological, and representational grounds of silence in Part's music; it listens with critical openness to the intersections of theology, sacred texts, and spirituality in Part's music; and it positions sensing, performing bodies at the center of musical experience. Building on the conventional score-, biography-, and media-based approaches, this volume reframes Part studies around the materiality of sound, its sacredness, and its embodied resonances within secular spaces.

Wireless Power Transfer (WPT) is considered to be an innovative game changing technology. The same radio wave and electromagnetic field theory and technology for wireless communication and remote sensing is applied for WPT. In conventional wireless communication systems, information is "carried" on a radio wave and is then transmitted over a distance. In WPT however, the energy of the radio wave itself is transmitted over a distance. Wireless communication technology has proven to be extremely useful, however in future it should be even more useful to apply both wireless communication and wireless power technologies together. There are various WPT technologies, e.g. inductive near field WPT, resonance coupling WPT, WPT via radio waves, and laser power transfer.

What role will biofuels play in the scientific portfolio that might bring energy independence and security, revitalize rural infrastructures, and wean us off of our addiction to oil? The shifting energy landscape of the 21st century, with its increased demand for renewable energy technology, poses a worrying challenge. Discussing the multidisciplinary study of bioenergy and its potential for replacing fossil fuels in the coming decades, Introduction to Biofuels provides a roadmap for understanding the broad sweep of technological, sociological, and energy policy issues that intermingle and intertwine. Copiously illustrated and with numerous examples, this book explores key technologies, including biotechnology, bioprocessing, and genetic reprogramming of microorganisms. The author examines the future of biofuels from a broader perspective, addressing the economic, social, and environmental issues crucial for studying the sustainable development of bioenergy. Each chapter begins with questions and provides the answers later in the chapter as key informational points. Embedded Science, Technology, Engineering, and Math (STEM) sections provide detailed derivations and equations for a subset of topics that can be found easily as buzzwords in popular media and on web sites. Together, the STEM topics form a thread of essential technologies and a guide to how researchers have established quantitative parameters that are crucial to the ever-growing biofuels database. With so much information scattered throughout the literature, it is often difficult to make sense of what is real and what is an optimistic selling of ideas with no scientific credibility. This book does an excellent job of filtering through volumes of data, providing a historical perspective on which to anchor the information, and outlining the strengths and constraints of the different biofuels.

The rapid increase of cloud computing, high performance computing (HPC) and the vast growth in Internet and Social Media use have aroused the interest in energy consumption and the carbon footprint of Data Centres. Data Centres primarily contain electronic equipment used for data processing (servers), data storage (storage equipment), and communications (network equipment). Collectively, this equipment processes, stores, and transmits digital information and is known as information technology (IT) equipment. Advanced Concepts for Renewable Energy Supply of Data Centres introduces a number of technical solutions for the supply of power and cooling energy into Data Centres with enhanced utilisation of renewable energy sources in order to achieve low energy Data Centres. Because of the high energy density nature of these unique infrastructures, it is essential to implement energy efficiency measures and reduce consumption before introducing any renewable energy source. A holistic approach is used with the objective of integrating many technical solutions such as management of the IT (Information Technology) load, efficient electrical supply to the IT systems, Low-Ex air-conditioning systems, interaction with district heating and cooling networks, re-use of heat, free cooling (air, seawater, groundwater), optimal use of heat and cold storage, electrical storage and integration in smart grids. This book is therefore a catalogue of advanced technical concepts that could be integrated into Data Centres portfolio in order to increase the overall efficiency and the share of renewable energies in power and cooling supply. Based on dynamic energy models implemented in TRNSYS some concepts are deeply evaluated through yearly simulations. The results of the simulation are illustrated with Sankey charts, where the energy flows per year within the subsystems of each concept for a selected scenario are shown, and graphs showing the results of parametric analysis. A set of environmental metrics (as the non-renewable primary energy) and financial metrics (CAPEX and OPEX) as well of energy efficiency metrics like the well-known PUE, are described and used to evaluate the different technical concepts.

Green Energy: Sustainable Electricity Supply with Low Environmental Impact defines the future of the world's electricity supply system, exploring the key issues associated with global warming, and which energy systems are best suited to reducing it. Electricity generation is a concentrated industry with a few sources of emissions, which can be controlled or legislated against. This book explains that a green sustainable electricity system is one whose construction, installation, and operation minimally affect the environment and produce power reliability at an affordable price. It addresses the question of how to build such an electricity supply system to meet the demands of a growing population without accelerating global warming or damaging the environment. The green argument for conservation and renewable energies is a contradiction in terms. Although they produce no emissions, because renewable systems are composed of a large number of small units, a considerable amount of energy is required to produce, erect, and maintain them. This book is a response to that conundrum, answering key questions, such as: How can renewables be exploited to contribute the greatest energy input? Should coal be used for clean fuel and chemical production rather than for power generation? How quickly can we start to build the Green Energy system? The author has more than forty years of experience as an international journalist reporting on power-generating technologies and on energy policies around the world. Detailing the developmental history, and current state, of the global nuclear industry, he discusses the dire, immediate need for large quantities of clean, emission-free electric power, for both domestic and industrial uses. This book details how current technologies-particularly nuclear, combined cycle, and hydro-can be applied to satisfy safely the growing energy demands in the future.

With different intensities, depending on the season, every morning and evening of any weekday there are the same peaks in electricity demand.
