Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to assess potential marine biomass sources and their preprocessing requirements. For the assessment of marine biomass sources, apriority list of marine plants was developed based on maximum potential organic yields, maximum potential calorific yields, and chemical composition. Yields were maximized and undesirable chemical properties minimized. The priority list was used to estimate maximum potential yields from U.S. coastal water (from shore tothe 200 -mile limit of the Fisheries Conservation Zone). Preprocessing schemes were compared based on a comparative evaluation of energy consumption for each preprocessing step. The priority list of potential biomass sources produced 13 potential genera; five showed calorific yields far in excess of the other eight. These five (Laminaria, Chondrus, Fucus, Gracilaria, and Macrocystis) had calorific yields in excess of50 x 103 kcal/m2 - yr. No genus was found to be universally applicable to all U.S. territorial waters. It was estimated that maximum potential national yield without mechanical nutrient upwelling could be as high as 30 x 105 Btu/yr (30 quad).Results of the preprocessing study indicated that harvesting and size reduction operations may consume a large proportion of the energy available from the harvested biomass. It was found that biochemical conversion preprocessing incurs the least energy loss. It was also found that thermochemical conversion is probably not appropriate for marine biomass due to preprocessing energy losses.

This book was released on 2012-12-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Countless pages have been written on alternative energy sources since the fall of 1973 when our dependence on fossil petroleum resources became a grim reality. One such alternative is the use of biomass for producing energy and liquid and gaseous fuels. The term "biomass" generally refers to renewable organic matter generated by plants through photosynthesis. Thus trees, agri cultural crops, and aquatic plants are prime sources of biomass. Furthermore, as these sources of biomass are harvested and processed into commercial prod ucts, residues and wastes are generated. These, together with municipal solid wastes, not only add to the total organic raw material base that can be utilized for energy purposes but they also need to be removed for environmental reasons. Biomass has been used since antiquity for energy and material needs. In is still one of the most sought-after energy sources in most of the fact, firewood world. Furthermore, wood was still a dominant energy source in the U. S. only a hundred years ago (equal with coal). Currently, biomass contributes about 15 2 quadrillion Btu (l quad = 10 Btu) of energy to our total energy consump tion of about 78 quad. Two quad may not seem large when compared to the contribution made by petroleum (38 quad) or natural gas (20 quad), but bio mass is nearly comparable to nuclear energy (2. 7 quad).

Available in PDF, EPUB and Kindle. Book excerpt: tions is not possible without first putting the problem into a wider con text. Consequently, before proceeding with detailed critical topical cov erage of individual biomass energy sources, uses, and effects, I will extend this preface with a few pages of rather personal reflections (I will use the same device in closing the book: after providing concise topical summaries in Chapter 8, I will conclude with some essayistic musings on renewable energetics, plants, people, and a scientist's responsibility). Interest in biomass energies is just a part of a broader global trend toward renewable energetics, a trend which has evolved speedily after the crude oil price escalation started in 1973. Yet one must be reminded that for the rich countries fossil fuels are, and for a long period shall remain, the foundation of an affluent civilization, while throughout the poor world the reliance of most people on biomass energies for everyday subsistence has brought many damaging environmental and social ef fects; that the reality of sharp price rises for crude oil (actually not so sharp once adjusted for inflation) should not be misconstrued as an "energy crisis"; that the rise of renew abies and the claims made on their behalf by countless enthusiasts look so much better on paper than in reality; and that the potential of biomass energies, an essential ingre dient of renewable scenarios, has been judged more with proselytizing zeal than with critical detachment.

Book excerpt: An objective, comprehensive, and accessible examination of today's most crucial problem: preserving the environment in the face of society's insatiable demand for energy. In Energy at the Crossroads, Vaclav Smil considers the twenty-first century's crucial question: how to reconcile the modern world's unceasing demand for energy with the absolute necessity to preserve the integrity of the biosphere. With this book he offers a comprehensive, accessible guide to today's complex energy issues—how to think clearly and logically about what is possible and what is desirable in our energy future. After a century of unprecedented production growth, technical innovation, and expanded consumption, the world faces a number of critical energy challenges arising from unequal resource distribution, changing demand patterns, and environmental limitations. The fundamental message of Energy at the Crossroads is that our dependence on fossil fuels must be reduced not because of any imminent resource shortages but because the widespread burning of oil, coal, and natural gas damages the biosphere and presents increasing economic and security problems as the world relies on more expensive supplies and Middle Eastern crude oil. Smil begins with an overview of the twentieth century's long-term trends and achievements in energy production. He then discusses energy prices, the real cost of energy, and "energy linkages"—the effect energy issues have on the economy, on quality of life, on the environment, and in wartime. He discusses the pitfalls of forecasting, giving many examples of failed predictions and showing that unexpected events can disprove complex models. And he examines the pros and cons not only of fossil fuels but also of alternative fuels such as hydroenergy, biomass energy, wind power, and solar power. Finally, he considers the future, focusing on what really matters, what works, what is realistic, and which outcomes are most desirable.

Available in PDF, EPUB and Kindle. Book excerpt: In Volume 6 of the Advances in Solar Energy we have specifically targeted for a review the rich experience of the Power Utilities. Their hands-on experience in a large variety of means to employ solar energy conversion and to evaluate the technical and economical feasibilities is of great importance to their future use. In designing the lay-out for this volume, we wanted to collect all relevant information, including success and failures and wanted to emphasize the lessons learned from each type of experiment. The publication of such a review now has the advantage of a settled experience in the first phase of solar involvement of the utility industry with a large amount of data analyzed. We are confident that this information will be of great value to direct the future development of the solar energy mix within this industry. We have added to this set of reviews three articles which deal with the most promising high-technology part of solar energy conversion using exclusively solid state devices: solar cells. The development over the last two decades from barely 10% to now in excess of 30% conversion efficiency is breathtaking. In addition, the feasibility of economic midrange efficient thin-film technology holds the promise of opening large sc ale markets in the near future. This field will enter head-on competition for large power generation with more conventional technology.
