In the future, our energy systems will need to be renewable and sustainable, efficient and cost-effective, convenient and safe. Hydrogen has been proposed as the perfect fuel for this future energy system. The availability of a reliable and cost-effective supply, safe and efficient storage, and convenient end use of hydrogen will be essential for a transition to a Hydrogen Economy. Research is being conducted throughout the world for the development of safe, cost-effective hydrogen production, storage, and end-use technologies that support and foster this transition. This book is a collection of important research and analysis papers on hydrogen production, storage, and end-use technologies that were presented at the American Chemical Society National Meeting in New Orleans, Louisiana, USA, in August 1999.

Until recently, the phenomenal economic development of the Asian tigers, Chile, and Malaysia, as well as the sustained economic growth of the United States, painted a very desirable and optimistic picture of free markets, fiscal responsibility, and, more generally, the entire dogma of neoclassical economics. As of the fall of 1998, however, the economies of many tropical countries have contracted severely, and the enthusiasm of the developing tropics for the free market and all of its ancillary policies is decidedly cooler. Have our traditional approaches to economics been failing the developing world? This interdisciplinary book covers the conditions of the developing tropics, the resistance of some of their problems to earlier attempts at solutions, and the use of new tools to develop a much more comprehensive and empirical framework for analysis and decision making. It also presents the development of cutting edge technology that links GIS and modeling approaches with extensive databases on meteorology, soils, agricultural production, and land use. The book discusses whether development is sustainable through a synthesis of demographic, economic, and resource-specific considerations. Costa Rica is uniquely suited to this study because of its size, stage of development, democratic institutions, and national databases. A CD-ROM containing all data and programs, color images, animated models, large data tables, and references accompanies the book. Key Features * Links economic and biophysical analyses of sustainability * Presents new tools and approaches for analysis and decision-making * Includes a CD-ROM containing data and programs, color images, animated models, and references.
