Introduces the field of hydrogen technology and explains the basic chemistry underlying promising and innovative new technologies This new and completely updated edition of Introduction to Hydrogen Technology explains, at an introductory level, the scientific and technical aspects of hydrogen technology. It incorporates information on the latest developments and the current research in the field, including: new techniques for isolating and storing hydrogen, usage as a fuel for automobiles, residential power systems, mobile power systems, and space applications. Introduction to Hydrogen Technology, Second Edition features classroom-tested exercises and sample problems. It details new economical methods for isolating the pure hydrogen molecule. These less expensive methods help make hydrogen fuel a very viable alternative to petroleum-based energy. The book also adds a new chapter on hydrogen production and batteries. It also provides in-depth coverage of the many technical hurdles in hydrogen storage. The developments in fuel cells since the last edition has been updated. Offers new chapters on hydrogen production, storage, and batteries Features new sections on advanced hydrogen systems, new membranes, greenhouse gas sensors and updated technologies involving solar and wind energies Includes problems at the end of the Chapters, as well as solutions for adopters This book is an introduction to hydrogen technology for students who have taken at least one course in general chemistry and calculus; it will also be a resource book for scientists and researchers working in hydrogen-based technologies, as well as anyone interested in sustainable energy.
This manual is designed for the use of hydrogen as a fuel in the fuel cells. The turn of the century has seen a realization of moving towards clean energy due to a variety of considerations ranging from global warming, anxiety to living in a healthy atmosphere, depletion of fossil fuels, oil slick in Gulf of Mexico resulting in disasters and so forth. Innumerable debates in the literature has led to the identification of hydrogen as the safest and efficient fuel over the other available fuels. This fuel can be used in two ways: a) direct combustion like gasoline and b) fuel cells. The use of it by the first method requires pure oxygen to be used for combustion; it is an expensive method involving oxygen storage and transportation. If oxygen is substituted by air in the combustion, it produces nitrogen oxides that are defying the definition of clean energy. The other method is to use it as a fuel cell for easy emission free transportation. Here chemical energy is converted to electrical energy directly in a fuel cell. To illustrate principles of related fuel cells, methanol and borohydride fuel cells are included in this manual. The nine experiments described here are designed for illustrating the concepts for the beginners and those motivated to go for clean energy.DVD displays the actual experimental set up and measurement procedures for Hydrogen safety; Fuel value measurement; Gaseous properties of hydrogen; Proton exchange membrane fuel cell assembly and Dissolved methanol fuel cell.
Understand the future of clean energy with this timely introduction Hydrogen is a clean fuel that can be used to power fuel cells whose only biproduct is water. This flexible energy carrier can be produced from a range of natural processes and domestic energy resources, and it has potentially widespread applications. In an era defined by global climate change and the search for sustainable energy, hydrogen energetics is a field with transformative potential. Hydrogen Energetics provides a cutting-edge introduction to current research and applications in this vital field. It offers an overview of hydrogen energy usage, including both positives and negatives, with a particular emphasis on the economic and infrastructural dimensions. Its up-to-date view of the state of the field and balance of theoretical and practical knowledge make it an essential resource. Hydrogen Energetics readers will also find: A one-stop resource for understanding the scientific foundations, applications, and environmental impacts of hydrogen utilization Detailed discussion of topics including hydrogen properties, hydrogen production, and key characteristics of fuel cells A focus on both technical and economic aspects of hydrogen energetics Hydrogen Energetics is a valuable source for researchers and academics in any field connected to renewable energies, energy storage, and environmental science, as well as for any professionals working with sustainability and natural resource availability.
