Energy and environmental security are major problems facing our global economy. Fossil fuels, particularly crude oil, are confined to a few regions of the world and the continuity of supply is governed by dynamic political, economic and ecological factors. These factors conspire to force volatile, often high fuel prices while, at the same time, environmental policy is - manding a reduction in greenhouse gases and toxic emissions. Yet incr- sed growth and demand for welfare by developed and developing countries are placing higher pressure on energy resources. In particular, a large fraction of "new consumers" in developing countries already reached a purchasing power high enough as to be able to access to commodity and energy markets worldwide, thus boosting energy consumption and competition for all kinds of resources. Such a trend, although in principle may represent a progress towards diffuse welfare and wealth as well as much needed equity, is at present contributing to a rush for the appropriation of available resources which are directly and indirectly linked to energy and may contribute to planetary instability if it is not adequately understood and managed. A coherent energy strategy is required, addressing both energy supply and demand, security of access, development problems, equity, market dy- mics, by also taking into account the whole energy lifecycle including fuel production, transmission and distribution, energy conversion, and the impact on energy equipment manufacturers and the end-users of energy systems.

Energy appears to be a fundamental driving force of economic and political strategies as well as planetary stability. Energy-related issues such as (1) the availability of new energy sources and viable technologies, (2) the disparity in access to energy sources, (3) the role of energy in our societies (energy societal metabolism), (4) the energy support to the life of our cities (where about half of world population is going to live very soon), and (5) the energy demand for food security all over the world, are "hot" problems that humans will have to face within the framework of sustainability (ecologically sound production and consumption patterns associated with socially acce- able life styles), in terms of policies, technological development and economic processes. A coherent energy strategy is required, addressing both energy supply and demand, security of access, development problems, equity, market dynamics, by also taking into account the whole energy lifecycle including fuel production, transmission and distribution, energy conversion, and the impact on energy equipment manufacturers and the end-users of energy systems. Issues of energy efficiency and rebound effect must also be taken into proper account. In the short term, the aim should be to achieve higher energy efficiencies and increased supply from local energy sources, in particular renewable energy sources.

Compendium of Hydrogen Energy: Hydrogen Energy Conversion, Volume Three is the third part of a four volume series and focuses on the methods of converting stored hydrogen into useful energy. The other three volumes focus on hydrogen production and purification; hydrogen storage and transmission; and hydrogen use, safety, and the hydrogen economy, respectively. Many experts believe that, in time, the hydrogen economy will replace the fossil fuel economy as the primary source of energy. Once hydrogen has been produced and stored, it can then be converted via fuel cells or internal combustion engines into useful energy. This volume highlights how different fuel cells and hydrogen-fueled combustion engines and turbines work. The first part of the volume investigates various types of hydrogen fuel cells, including solid oxide, molten carbonate, and proton exchange membrane. The second part looks at hydrogen combustion energy, and the final section explores the use of metal hydrides in hydrogen energy conversion.

Fuel Cells for Transportation: Fundamental Principles and Applications is the first comprehensive reference on the application of fuel cells for light- and heavy-duty transportation. Addressing the subject from both a materials and engineering perspective, the book examines integration, modeling, and optimization of fuel cells from fundamentals to the latest advances. Chapters address every aspect of fuel cell systems for transport applications, including performance optimization, stack characterization, low-cost materials and catalysts, design of bipolar plates and flow fields, water and thermal management, durability under automotive driving cycles, cold start, state of the art characterization, optimization of various components, and more. Each chapter reviews the fundamental principles of the topic before going on to examine the latest developments alongside current applications and real-world case studies. This is an essential reference for graduate students and researchers working on fuel cells for transport applications, as well as professional engineers involved in the application of fuel cells and clean energy and working in any sector of the transportation industry.
