Volume 1 of a 4-volume series is a concise, authoritative and an eminently readable and enjoyable experience related to hydrogen production, storage and usage for portable and stationary power. Although the major focus is on hydrogen, discussion of fossil fuels and nuclear power is also presented where appropriate. This monograph is written by recognized experts in the field, and is both timely and appropriate as this decade will see application of hydrogen as an energy carrier, for example in transportation sector. The world's reliance on fossil fuels is due to the ever growing need for energy to sustain life and on-going progress; however exploitation also brings consequences such as emission of carbon, nitrogen and sulfur dioxides into the atmosphere. The collective influence of these photochemical gases is production of acid rain and an alternation of global temperatures, leading to record high temperatures in many parts of the world. The fossil fuel is unsustainable and thus there is a critical need for alternative sustainable energy resources. One universal energy carrier is hydrogen, which is the focus of this volume. This book is suitable for those who work in the energy field as technical experts, including engineers and scientists, as well as managers, policy and decision-makers, environmentalists and consultants. Students and practitioners such as lectures, teachers, legislators and their aids in the field of energy will find this book invaluable and a practical handbook or guide in the field of sustainable energy with emphasis on hydrogen as an energy carrier.

MATERIALS FOR HYDROGEN PRODUCTION, CONVERSION, AND STORAGE Edited by one of the most well-respected and prolific engineers in the world and his team, this book provides a comprehensive overview of hydrogen production, conversion, and storage, offering the scientific literature a comprehensive coverage of this important fuel. Continually growing environmental concerns are driving every, or almost every, country on the planet towards cleaner and greener energy production. This ultimately leaves no option other than using hydrogen as a fuel that has almost no adverse environmental impact. But hydrogen poses several hazards in terms of human safety as its mixture of air is prone to potential detonations and fires. In addition, the permeability of cryogenic storage can induce frostbite as it leaks through metal pipes. In short, there are many challenges at every step to strive for emission-free fuel. In addition to these challenges, there are many emerging technologies in this area. For example, as the density of hydrogen is very low, efficient methods are being developed and engineered to store it in small volumes. This groundbreaking new volume describes the production of hydrogen from various sources along with the protagonist materials involved. Further, the extensive and novel materials involved in conversion technologies are discussed. Also covered here are the details of the storage materials of hydrogen for both physical and chemical systems. Both renewal and non-renewal sources are examined as feedstocks for the production of hydrogen. The non-renewal feedstocks, mainly petroleum, are the major contributor to date but there is a future perspective in a renewal source comprising mainly of water splitting via electrolysis, radiolysis, thermolysis, photocatalytic water splitting, and biohydrogen routes. Whether for the student, veteran engineer, new hire, or other industry professionals, this is a must-have for any library.

The announcement of a hydrogen fuel initiative in the President's 2003 State of the Union speech substantially increased interest in the potential for hydrogen to play a major role in the nation's long-term energy future. Prior to that event, DOE asked the National Research Council to examine key technical issues about the hydrogen economy to assist in the development of its hydrogen R&D program. Included in the assessment were the current state of technology; future cost estimates; CO2 emissions; distribution, storage, and end use considerations; and the DOE RD&D program. The report provides an assessment of hydrogen as a fuel in the nation's future energy economy and describes a number of important challenges that must be overcome if it is to make a major energy contribution. Topics covered include the hydrogen end-use technologies, transportation, hydrogen production technologies, and transition issues for hydrogen in vehicles.

The gradual increase of population and the consequential rise in the energy demands in the recent years have led to the overwhelming use of fossil fuels. Hydrogen has recently gained substantial interest because of its outstanding features to be used as clean energy carrier and energy vector. Moreover, hydrogen appears to be an effective alternative to tackle the issues of energy security and greenhouse gas emissions given that it is widely recognized as a clean fuel with high energy capacity. Hydrogen can be produced by various techniques such as thermochemical, hydrothermal, electrochemical, electrolytic, biological and photocatalytic methods as well as hybrid systems. New Dimensions in Production and Utilization of Hydrogen emphasizes on the research, development and innovations in the production and utilization of hydrogen in the industrial biorefining, hydrotreating and hydrogenation technologies, fuel cells, aerospace sector, pharmaceuticals, metallurgy, as well as bio-oil upgrading. Moreover, the supply chain analysis, lifecycle assessment, techno-economic analysis, as well as strengths and threats of global hydrogen market are covered in the book. This book provides many significant insights and scientific findings of key technologies for hydrogen production, storage and emerging applications. The book serves as a reference material for chemical and biochemical engineers, mechanical engineers, physicists, chemists, biologists, biomedical scientists and scholars working in the field of sustainable energy and materials. - Discusses the efficient usage of hydrogen as standalone fuel or feedstock in downstream processing - Outlines key technologies for hydrogen production and their emerging applications - Includes innovative approaches to the research and applications of hydrogen, including hydrotreating technologies, fuel cell vehicles and green fuel synthesis, the aerospace sector, pharmaceuticals, carbon dioxide hydrogenation, and bio-oils upgrading - Serves as a reference for chemical, biochemical, and mechanical engineers, physicists, chemists, biologists, and biomedical scientists working in sustainable energy and materials
