Book Description
This book explains why conventional energy analysis and statistics are not useful for generating robust energy scenarios and effective assessments of the quality of alternative energy sources. Then it presents an innovative multi-scale approach, illustrated with empirical results, for effectively dealing with sustainability in face of the coming energy crisis.

Book Description
The fields covered by the hydrogen energy topic have grown rapidly, and now it has become clearly multidisciplinary. In addition to production, hydrogen purification and especially storage are key challenges that could limit the use of hydrogen fuel. In this book, the purification of hydrogen with membrane technology and its storage in "solid" form using new hydrides and carbon materials are addressed. Other novelties of this volume include the power conditioning of water electrolyzers, the integration in the electric grid of renewable hydrogen systems and the future role of microreactors and micro-process engineering in hydrogen technology as well as the potential of computational fluid dynamics to hydrogen equipment design and the assessment of safety issues. Finally, and being aware that transportation will likely constitute the first commercial application of hydrogen fuel, two chapters are devoted to the recent advances in hydrogen fuel cells and hydrogen-fueled internal combustion engines for transport vehicles. - Hydrogen from water and biomass considered - Holistic approach to the topic of renewable hydrogen production - Power conditioning of water electrolyzers and integration of renewable hydrogen energy systems considered - Subjects not included in previous books on hydrogen energy - Micro process technology considered - Subject not included in previous books on hydrogen energy - Applications of CFD considered - Subject not included in previous books on hydrogen energy - Fundamental aspects will not be discussed in detail consciously as they are suitably addressed in previous books - Emphasis on technological advancements - Chapters written by recognized experts - Up-to date approach to the subjects and relevant bibliographic references

Book Description
Imagine fuel without fear. No climate change. No oil spills, no dead coalminers, no dirty air, no devastated lands, no lost wildlife. No energy poverty. No oil-fed wars, tyrannies, or terrorists. No leaking nuclear wastes or spreading nuclear weapons. Nothing to run out. Nothing to cut off. Nothing to worry about. Just energy abundance, benign and affordable, for all, forever. That richer, fairer, cooler, safer world is possible, practical, even profitable-because saving and replacing fossil fuels now works better and costs no more than buying and burning them. Reinventing Fire shows how business-motivated by profit, supported by civil society, sped by smart policy-can get the US completely off oil and coal by 2050, and later beyond natural gas as well. Authored by a world leader on energy and innovation, the book maps a robust path for integrating real, here-and-now, comprehensive energy solutions in four industries-transportation, buildings, electricity, and manufacturing-melding radically efficient energy use with reliable, secure, renewable energy supplies.Popular in tone and rooted in applied hope, Reinventing Fire shows how smart businesses are creating a potent, global, market-driven, and explosively growing movement to defossilize fuels. It points readers to trillions in savings over the next 40 years, and trillions more in new business opportunities.Whether you care most about national security, or jobs and competitive advantage, or climate and environment, this major contribution by world leaders in energy innovation offers startling innovations will support your values, inspire your support, and transform your sense of possibility.Pragmatic citizens today are more interested in outcomes than motives. Reinventing Fire answers this trans-ideological call. Whether you care most about national security, or jobs and competitive advantage, or climate and environment, its startling innovations will support your values, inspire your support, and transform your sense of possibility.

Book Description
The Energy Return on Energy Invested (EROI or EROEI) is the amount of energy acquired from a particular energy source divided by the energy expended, or invested, in obtaining that energy. EROI is an essential and seemingly simple measure of the usable energy or “energy profit” from the exploitation of an energy source, but it is not so easy to determine all of the energy expenditures that should be included in the calculation. Because EROI values are generally low for renewable energy sources, differences in these estimates can lead to sharply divergent conclusions about the viability of these energy technologies. This book presents the first complete energy analysis of a large-scale, real-world deployment of photovoltaic (PV) collection systems representing 3.5 GW of installed, grid-connected solar plants in Spain. The analysis includes all of the factors that limit and adjust the real electricity output through one full-year cycle, and all of the fossil fuel inputs required to achieve these results. The authors’ comprehensive analysis of energy inputs, which assigns energy cost estimates to all financial expenditures, yields EROI values that are less than half of those claimed by other investigators and by the solar industry. Sensitivity analysis is used to test various assumptions in deriving these EROI estimates. The results imply that the EROI of current, large-scale PV systems may be too low to seamlessly support an energy and economic transition away from fossil fuels. Given the pervasiveness of fossil fuel subsidies in the modern economy, a key conclusion is that all components of the system that brings solar power to the consumer, from manufacturing to product maintenance and life cycle, must be improved in terms of energy efficiency. The materials science of solar conversion efficiency is only one such component. Sunny Spain represented an ideal case study as the country had the highest penetration of solar PV energy at 2.3 percent of total national demand as well as state-of-the-art expertise in solar power including grid management of intermittent, modern renewable systems. This book, written by a uniquely qualified author team consisting of the chief engineer for several major photovoltaic projects in Spain and the world’s leading expert on the concept and application of EROI, provides a comprehensive understanding of the net energy available to society from energy sources in general and from functioning PV installations under real-world conditions in particular. The authors provide critical insight into the capacity of renewable energy sources to fill the foreseeable gap between world energy demand and depletion rates for fossil fuels. · Presents the first comprehensive study of the EROI of large-scale solar PV systems in a developed country · Uses real-world operational data rather than laboratory approximations and extrapolations · Describes the dependence of one alternative energy source on the goods and services of a fossil-fueled economy · Has global implications for the potential of renewable energy sources to replace dwindling reserves of fossil fuels · Written with the first-hand knowledge of the chief, on-site engineer for many solar installations in Spain together with the leader in the development and application of the concept of EROI
