The Nature of the Hydrogen Bond $130 Hydrogen bond (H-bond) effects are known: it makes sea water liquid, joins cellulose microfibrils in trees, shapes DNA into genes and polypeptide chains into wool, hair, muscles or enzymes. Its true nature is less known and we may still wonder why O-H...O bond energies range from less than 1 to more than 30 kcal/mol without apparent reason. This H-bond puzzle is re-examined here from its very beginning and presented as an inclusive compilation of experimental H-bond energies andgeometries.New concepts emerge from this analysis: new classes of systematically strong H-bonds (CAHBs and RAHBs: charge- and resonance-assisted H-bonds); full H-bond classification in six classes (the six chemical leitmotifs); and assessment of the covalent nature of strong H-bonds. This leads to three distinct but inter-consistent models able to rationalize the H-bond and predict its strength, based on classical VB theory, matching of donor-acceptor acid-base parameters (PA or pKa), or shape of theH-bond proton-transfer pathway. Applications survey a number of systems where strong H-bonds play an important functional role, namely drug-receptor binding, enzymatic catalysis, ion-transport through cell membranes, crystal design and molecular mechanisms of functional materials.

Hydrogen Energy (Hardcover) $163.4 A transition to renewable and low-carbon forms of energy is being widely debated as a means of securing a sustainable future for mankind. Hydrogen Energy Challenges and Prospects, a new book from the authors of Clean Energy, considers the prospects for hydrogen as a universal energy vector and fuel for the decades to come. With no emissions other than water arising from its combustion, the potential virtues of harnessing and utilizing hydrogen correlate with recent growing concern over the security of conventional fuel supply and global climate change. This book sets out to analyze the technical situation in an objective fashion, free from the constraints of political and industrial loyalties. Areas covered include pathways to hydrogen production, prospects for carbon capture and storage, options for hydrogen storage on vehicles, fuel cells, and fuel cell vehicles. Each of the many facets of hydrogen energy is discussed and the challenges to be faced are addressed. The authors acknowledge it is not possible to reach a simple, unequivocal conclusion regarding overall prospects, since the international energy scene is so complex, and predicting long-term futures is so notoriously difficult. Nevertheless, the reader will be given compelling pointers indicative of the way in which events might develop. This topical book is ideal for undergraduates, postgraduates and academics with an interest in hydrogen energy. Government agencies and energy professionals will also find this content to be a useful reference source.

Pathways to a Hydrogen Future $102 Hydrogen may someday fuel our cars and power and heat our homes and businesses and revolutionize the way we use energy. Moving to a hydrogen economy could help reduce our reliance on foreign oil, improve local air quality, and reduce the risk of climate change. Despite the potential of hydrogen, there is no guarantee that the hydrogen economy will happen as the obstacles are considerable and the competing visions are many. Pathways to a Hydrogen Future seeks to untangle the competing visions of a hydrogen economy, explain the trade-offs and obstacles and offer recommendations for a path forward. The results are based on a detailed simulation model developed at Sandia National Laboratories: "The Hydrogen Futures Simulation Model (H2Sim)". The H2Sim is a high-level strategic tool for evaluating the economic and environmental trade-offs of alternative hydrogen production, storage, transport, and end use options in the year 2020. An executive version of H2Sim is included with the book allowing readers to explore the various scenarios discussed. H2Sim's ease of use and its ability to provide answers to these types of questions make it a powerful educational and policy making tool. The model's structure is ideal for exploring "what-if" questions, such as: Can fuel cell vehicles (FCVs) compete economically with current cars if the FCVs are 2.5 times as efficient? Should the hydrogen be produced at fueling stations or at central locations and transported to fueling stations? * Includes an executive version of H2Sim allowing readers to explore the various scenarios discussed * H2Sim's ease of use and ability to provide answers makes it a powerful educational and policy making tool * The model's structure is ideal for exploring "what-if" questions, such as: Can fuel cell vehicles (FCVs) compete economically with current cars if the FCVs are 2.5 times as efficient?

Handbook of Hydrogen Storage $179.99 Owing to the limited resources of fossil fuels, hydrogen is proposed as an alternative and environment-friendly energy carrier. However, its potential is limited by storage problems, especially for mobile applications. Current technologies, as compressed gas or liquefied hydrogen, comprise severe disadvantages and the storage of hydrogen in lightweight solids could be the solution to this problem. Since the optimal storage mechanism and optimal material have yet to be identified, this first handbook on the topic provides an excellent overview of the most probable candidates, highlighting both their advantages as well as drawbacks.

Hydrogen Storage Materials (Hardcover) $234.68 Hydrogen is widely billed as the fuel of the future. For this to be a reality there is a pressing need for a safe, economic and reliable way to transport hydrogen, particularly for automotive applications. This has prompted a world-wide effort to develop novel materials that are re-usable and capable of storing and releasing significant (> 6 wt%) quantities of hydrogen. In addition to compressed (either liquid or gaseous) hydrogen, two main themes are being explored: adsorption of hydrogen by materials and "chemical hydrogen" where hydrogen is reacted with a material. The discussion will focus on both themes, from synthesis and characterisation to application of such novel materials. The focus will be on the wider issues involved in synthetic routes, characterisation, materials properties, rather than simply on examples. The importance of the interplay of theory and experiment will be stressed. Faraday Discussion 151, organised by the Faraday Division, aims to bring together the diverse range of workers in the field of hydrogen storage materials, from those involved in materials discovery and characterisation, to those studying mechanisms or developing applications. The Discussion will both inform people of alternative strategies and encourage new ideas and approaches. The themes cover: -Application of theory and spectroscopic methods to understand hydrogenation/dehydrogenation mechanisms -Novel approaches such as catalysed hydrogenation/dehydrogenation of organic molecules, encapsulation of nanosized materials in carbon or polymers -Chemical hydrogen: characterisation and properties of main group and transition metal borohydrides and alanates, ternary and quaternary metal hydrides, reactive hydride composites -Adsorbed/physisorbed hydrogen on or in MOFs, promoted carbons and other materials with large internal or external surface area -Applications including uses for automotives and novel battery materials
