This book advances the use of biodiesel-more environmentally friendly than traditional fossil fuels-by showing how it can be synthesized at a lower cost, with greater efficiency and as a more pure and stable product. It presents methods based on fluorescence spectroscopy, which are less time-consuming than the traditional Rancimat analysis for monitoring stability, and are therefore less prone to allowing oxidative decay in the biofuel. Biodiesel exploits a variety of raw materials, from freshly harvested cottonseed to recycled cooking oil. These are cheap to produce and generate fuel lower in polluting sulphur and aromatic compounds than its petroleum-based equivalent. Beginning by addressing different protocols for synthesis based on fatty acids, methyl and ethyl esters, it then describes chemical analyses essential to establishing the purity of the biodiesel. It highlights in detail the use of multifunctional and synthetic antioxidants, and investigates the impact of synthetic chalcones and their derivatives on the oxidative stability of biodiesel. The author goes on to explain how to ameliorate various influences - UV irradiation and metal contaminants for example - which increase the hazards of oxidation, such as degradation and instability. New pre-treatment procedures performed using ultrasonic energies, thermostatic bath and vortex stirring are not only more environmentally friendly, but cut down on the time-consuming process of determining metal content, and allow for the use of more environmentally friendly aqueous reagents. The book investigates and demonstrates these techniques on the basis of real-world results. Further, it suggests the practical uses of byproducts of biodiesel production, for example, using glycerol as a source of energy and high valuable chemicals. These useful techniques aid any researcher exploring the production process of biodiesel and its stabilization and characteristics.
Over the last century, energy storage systems (ESSs) have continued to evolve and adapt to changing energy requirements and technological advances. Energy Storage in Power Systems describes the essential principles needed to understand the role of ESSs in modern electrical power systems, highlighting their application for the grid integration of renewable-based generation. Key features: Defines the basis of electrical power systems, characterized by a high and increasing penetration of renewable-based generation. Describes the fundamentals, main characteristics and components of energy storage technologies, with an emphasis on electrical energy storage types. Contains real examples depicting the application of energy storage systems in the power system. Features case studies with and without solutions on modelling, simulation and optimization techniques. Although primarily targeted at researchers and senior graduate students, Energy Storage in Power Systems is also highly useful to scientists and engineers wanting to gain an introduction to the field of energy storage and more specifically its application to modern power systems.
This book describes step-by-step the entire building process of a passive, energy-efficient house in a Mediterranean climate. It chronicles the creation of the Fiorita Passive House in Cesena, Italy, offering designers valuable tips and practical advice for their own projects. Written as a logbook, it not only provides essential technical information but is also an exciting story of the challenges encountered and the solutions that were found. ´´How and where do I start when building a passive house? Do I need consultants? Will it cost too much? What precautions should I take in a Mediterranean region? What tools do I need? I want to build in wood, but what technical solutions should I use? What must I do regarding plants and equipment? And then, finally, will it really work?´´ These and many other questions filled the head of the author and designer when he tried his hand at building a passive house in the Mediterranean. The designer, S. Piraccini, had long sought a book that would answer these answers - in vain. So he decided to brave these dangerous waters alone, and after successfully completing his project, he decided to write a book to help others in the same situation. The book is accompanied by detailed information on building physics and HVAC systems by his fellow architect, K. Fabbri.
Photovoltaic Power System: Modelling, Design and Control is an essential reference with a practical approach to photovoltaic (PV) power system analysis and control. It systematically guides readers through PV system design, modelling, simulation, maximum power point tracking and control techniques making this invaluable resource to students and professionals progressing from different levels in PV power engineering. The development of this book follows the author´s 15-year experience as an electrical engineer in the PV engineering sector and as an educator in academia. It provides the background knowledge of PV power system but will also inform research direction. Key features: Details modern converter topologies and a step-by-step modelling approach to simulate and control a complete PV power system. Introduces industrial standards, regulations, and electric codes for safety practice and research direction. Covers new classification of PV power systems in terms of the level of maximum power point tracking. Contains practical examples in designing grid-tied and standalone PV power systems. Matlab codes and Simulink models featured on a Wiley hosted book companion website.
In this updated edition of a groundbreaking text, concepts such as energy return on investment (EROI) provide powerful insights into the real balance sheets that drive our ´´petroleum economy.´´ Hall and Klitgaard explore the relation between energy and the wealth explosion of the 20th century, and the interaction of internal limits to growth found in the investment process and rising inequality with the biophysical limits posed by finite energy resources. The authors focus attention on the failure of markets to recognize or efficiently allocate diminishing resources, the economic consequences of peak oil, the high cost and relatively low EROI of finding and exploiting new oil fields, including the much ballyhooed shale plays and oil sands, and whether alternative energy technologies such as wind and solar power can meet the minimum EROI requirements needed to run society as we know it. For the past 150 years, economics has been treated as a social science in which economies are modeled as a circular flow of income between producers and consumers. In this ´´perpetual motion´´ of interactions between firms that produce and households that consume, little or no accounting is given of the flow of energy and materials from the environment and back again. In the standard economic model, energy and matter are completely recycled in these transactions, and economic activity is seemingly exempt from the Second Law of Thermodynamics. As we enter the second half of the age of oil, when energy supplies and the environmental impacts of energy production and consumption are likely to constrain economic growth, this exemption should be considered illusory at best. This book is an essential read for all scientists and economists who have recognized the urgent need for a more scientific, empirical, and unified approach to economics in an energy-constrained world, and serves as an ideal teaching text for the growing number of courses, such as the authors´ own, on the role of energy in society.
