A hydrogen economy, in which this one gas provides the source of all energy needs, is often touted as the long-term solution to the environmental and security problems associated with fossil fuels. However, before hydrogen can be used as fuel on a global scale we must establish cost effective means of producing, storing, and distributing the gas, develop cost efficient technologies for converting hydrogen to electricity (e.g. fuel cells), and creating the infrastructure to support all this. Sorensen is the only text available that provides up to date coverage of all these issues at a level appropriate for the technical reader.

The book not only describes the "how" and "where" aspects of hydrogen fuels cells usage, but also the obstacles and benefits of its use, as well as the social implications (both economically and environmental). Written by a world-renowned researcher in energy systems, this thoroughly illustrated and cross-referenced book is an excellent reference for researchers, professionals and students in the field of renewable energy.

Updated sections on PEM fuel cells, Molten carbonate cells, Solid Oxide cells and Biofuel cells Updated material to reflect the growing commercial acceptance of stationary and portable fuel cell systems, while also recognizing the ongoing research in automotive fuel cell systems A new example of a regional system based on renewable energy sources reflects the growing international attention to uses of renewable energy as part of the energy grid Examples of life cycle analysis of environmental and social impacts

While solar is the fastest-growing energy source in the world, key concerns around solar power's inherent variability threaten to de-rail that scale-up . Currently, integration of intermittent solar resources into the grid creates added complication to load management, leading some utilities to reject it altogether, while other operators may penalize the producers via rate increases or force solar developers to include storage devices on-site to smooth out power delivery at the point of production. However these efforts at mitigation unfold, it is increasingly clear to parties on all sides that energy storage will be pivotally important in the drive to boost the integration of variable renewable sources into power infrastructures across the globe. Thoughtfully implemented storage technologies can reduce peak demand, improve day-to-day reliability, provide emergency power in case of interrupted generation, reduce consumer and utility costs by easing load balance challenges, decrease emissions, and increase the amount of distributed and renewable energy that makes it into the grid. While energy storage has long been an area of concern for scientists and engineers, there has been no comprehensive single text covering the storage methods available to solar power producers, which leaves a lamentable gap in the literature core to this important field. Solar Energy Storage aims to become the authoritative work on the topic, incorporating contributions from an internationally recognized group of top authors from both industry and academia, focused on providing information from underlying scientific fundamentals to practical applications, and emphasizing the latest technological developments driving this discipline forward.

Expert contributing authors explain current and emergent storage technologies for solar, thermal, and photovoltaic applications Sheds light on the economic status of solar storage facilities, including case studies of the particular challenges that solar energy systems present to remote locations Includes information on: chemical storage mechanisms, mechanical storage tactics, pumped hydro, thermal storage, and storage strategies for systems of all sizes-from centralized utilities to distributed generation

Bent S�rensen, one of the world's leading experts in the field of renewable energy systems, explores the current hurdles to the universal adoption of renewable energy sources and proposes solutions to the current situation in this new inspiring work. He discusses the social, political and economic issues that make sustainability seem like such an attainable goal, and explores the ways through which change can be achieved without loss of welfare.

Even though the author has written several scientific monographs covering the technical issues behind the energy and social transitions mentioned in this book, and bases his conclusions on solid facts and analysis, S�rensen avoids specialist jargon in this text. He therefore addresses scientists and engineers directly involved in sustainable technologies, as well as energy planners and decision makers in industry and government, and also those interested in the direction in which our societies are moving. This book can be a good basis for discussions and debate, whether in academic or in political circles, and may even be used as complementary reading for students in the field of energy generation, implementation, planning, management, markets and policy.

One of the world's leading experts in renewable energy systems looks into economic, social and political factors that influence the current state of renewable energy implementation in the world. S�rensen examines the reasons why reaching 100% renewable and sustainable energy sources might seem like an unattainable goal, and proposes alternative solutions that would allow the world to proceed towards energy sustainability without losing welfare.

In this seminal book, Bent Sørensen views human society as driven by the quest for, and control of, energy. From allowing our prehistoric ancestors to survive harsh northern European winters to more recent global energy security and climate concerns, the control and effective harnessing of energy sources has played a central role in human development. Using the written and archaeological record and, from earlier times, inferring the energy needs of humans through modeling of climatological conditions and other indirect parameters, Sørensen unwraps this previously little-explored field. Based on detailed studies of northern Europe – and in particular the case of Denmark – the focus moves from the stone age, through the development of agriculture and trade, migration and exploration, medieval society and the renaissance, into industrial times and present-day debates around the transition to low-carbon forms of energy supply. This riveting examination of a nascent field of study provides a new perspective for historians and those wishing to gain a deeper understanding of the background to present-day energy debates.
