Book Description
The support for polygeneration lies in the possibility of integrating different technologies into a single energy system, to maximize the utilization of both fossil and renewable fuels. A system that delivers multiple forms of energy to users, maximizing the overall efficiency makes polygeneration an emerging and viable option for energy consuming industries. Polygeneration Systems: Design, Processes and Technologies provides simple and advanced calculation techniques to evaluate energy, environmental and economic performance of polygeneration systems under analysis. With specific design guidelines for each type of polygeneration system and experimental performance data, referred both to single components and overall systems, this title covers all aspects of polygeneration from design to operation, optimization and practical implementation. Giving different aspects of both fossil and non-fossil fuel based polygeneration and the wider area of polygeneration processes, this book helps readers learn general principles to specific system design and development through analysis of case studies, examples, simulation characteristics and thermodynamic and economic data. - Detailed economic data for technology to assist developing feasibility studies regarding the possible application of polygeneration technologies - Offers a comprehensive list of all current numerical and experimental results of polygeneration available - Includes simulation models, cost figures, demonstration projects and test standards for designers and researchers to validate their own models and/or to test the reliability of their results

Book Description
It is widely believed that a large proportion of greenhouse gas emissions originated anthropogenically from the use of fossil fuels with additional contributions coming from manufactured materials, deforestation, soil erosion, and agriculture (including livestock). The global society actively supports measures to create a flexible and low-carbon energy economy to attenuate climate change and its devastating environmental consequences. In this Special Issue, the recent advancements in the next-generation thermochemical conversion processes for solid fuels and renewable energies (e.g., the operational flexibility of co-combustion of biomass and lignite, integrated solar combined cycle power plants, and advanced gasification systems such as the sorption-enhanced gasification and the chemical looping gasification) were shown.

Book Description
Esta investigación se centra en la evaluación termoeconómica para la producción conjunta de electricidad, agua, refrigeración, y calor de proceso en plantas de poligeneración solar, con el fin de crear una base de conocimiento científico para el desarrollo de tecnologías de plantas de potencia de concentración solar (CSP) en zonas con altas condiciones de irradiación solar, y el uso racional y óptimo de recursos en esquemas de poligeneración para aumentar la eficiencia global de conversión de energía del sistema, y minimizar los costos de los productos finales. El objetivo principal de esta disertación es modelar, evaluar y optimizar plantas de poligeneración solar, configuradas con una planta CSP con un campo de colectores solares cilindro parabólico, almacenamiento térmico de energía y un sistema de respaldo, un módulo de destilación multi-efectos (MED), un módulo de refrigeración de absorción de simple efecto (REF), y un módulo de calor de proceso (PH), donde el motor impulsor es la planta CSP, considerando que las plantas de poligeneración se localiza en una zona con altas condiciones de irradiación solar y de demanda de energía y agua. Las plantas de poligeneración solar se simulan en un régimen transitorio, en una ubicación representativa con altas condiciones de irradiación solar, como en el norte de Chile. En el desarrollo de esta disertación se utilizaron los programas IPSEpro, Microsoft Excel, MATLAB, EES, y el módulo ExIO como complemento de Microsoft Excel. Para ampliar el análisis termoeconómico en la evaluación de esquemas de poligeneración solar, la metodología incluye el uso de dos métodos termoeconómicos; el primero, basado en el método de costo de exergía, se utilizó para evaluar el costo real de cada producto, en el análisis de sensibilidad del costo de inversión, costo de combustible y de la demanda, y para evaluar los efectos del tamaño del campo solar y el dimensionamiento del almacenamiento de energía térmica. Se investigaron tres configuraciones: dos esquemas de poligeneración y uno de sistemas independientes. Además, se comparó con el método de costo nivelado en términos de asignación de costos y del costo especifico unitario de cada producto. Mientras que el segundo método, basado en el método de exergoeconomía simbólica, se utilizó para analizar en profundidad el proceso de formación de costos de exergía, comparándolo con sistemas independientes, y para establecer la mejor configuración en cogeneración, trigeneración y poligeneración. En el cual, se investigaron veintiún configuraciones: ocho de cogeneración, ocho de trigeneración, cuatro esquemas de poligeneración, y uno de sistemas independientes. Esta disertación fue desarrollada a través de tres artículos científicos. Este estudio revela que una planta de poligeneración solar es más eficiente y rentable que las plantas independientes para una zona con altas condiciones de irradiación solar y proximidad a centros de consumo, como las industrias mineras, que requieren operación continua y suministro de energía y agua con una demanda fundamentalmente constante. Además, de acuerdo con el mercado del norte de Chile, las configuraciones de poligeneración solar son competitivas en cuanto a la producción de electricidad, agua dulce, refrigeración y producción de calor. A su vez, las plantas de poligeneración solar podrían aumentar el beneficio económico vendiendo créditos de carbono y créditos de cuotas de energía renovable basados en el Protocolo de Kyoto y la legislación chilena, respectivamente. También revela que el método termoeconómico es un método de asignación de costos equitativo y racional que es adecuado para ser aplicado en una planta de poligeneración solar. Otro resultado es que este método se recomienda cuando se necesita un análisis más preciso para evaluar los costos de los diferentes productos y para evaluar los beneficios de una planta de poligeneración, en comparación con las plantas independientes. Por otro lado, el método de costo nivelado es un método simple y rápido, y no se requiere un profundo conocimiento de termodinámica, siendo recomendable cuando es necesario realizar un primer acercamiento de los costos de cada producto. Otro resultado importante es que los equipos claves en los cuales el diseño debería ser mejorado en las plantas de multi-generación solar son: colectores solares, subsistemas productivos (plantas MED, REF, y PH), evaporador, y recalentador. También, las configuraciones recomendadas en las plantas de multi-generación solar (cogeneración, trigeneración, y poligeneración) son aquellas en las cuales la planta MED reemplaza al condensador, y la planta REF, así como el módulo PH, se acoplan a las extracciones de turbina. Los resultados obtenidos brindan información útil para señalar el potencial que ofrece la poligeneración solar y podría constituir una guía para comprender estos métodos.

Book Description
A growing proportion of the world’s population is dependent on Seawater Desalination as a source of fresh water for both potable and civil use. One of the main drawbacks of conventional desalination technologies is the substantial energy requirement, which is facing cost increases in the global energy market. "Seawater Desalination" presents an overview of conventional and non-conventional technologies, with a particular focus on the coupling of renewable energies with desalination processes. The first section of this book presents, in a technical but reader-friendly way, an overview of currently-used desalination processes, from thermal to membrane processes, highlighting the relevant technical features, advantages and disadvantages, and development potential. It also gives a rapid insight into the economic aspects of fresh water production from seawater. The second section of the book presents novel processes which use Renewable Energies for fresh water production. From the first solar still evaporators, which artificially reproduced the natural cycle of water, technology has progressed to develop complex systems to harness energy from the sun, wind, tides, waves, etc. and then to use this energy to power conventional or novel desalination processes. Most of these processes are still at a preliminary stage of development, but some are already being cited as examples in remote areas, where they are proving to be valuable in solving the problems of water scarcity. A rapid growth in these technologies is foreseen in the coming years. This book provides a unique foundation, within the context of present and future sustainability, for professionals, technicians, managers, and private and public institutions operating in the area of fresh water supply.

Book Description
After decades of research and development, concentrating solar thermal (CST) power plants (also known as concentrating solar power (CSP) and as Solar Thermal Electricity or STE systems) are now starting to be widely commercialized. Indeed, the IEA predicts that by 2050, with sufficient support over ten percent of global electricity could be produced by concentrating solar thermal power plants. However, CSP plants are just but one of the many possible applications of CST systems. Advances in Concentrating Solar Thermal Research and Technology provides detailed information on the latest advances in CST systems research and technology. It promotes a deep understanding of the challenges the different CST technologies are confronted with, of the research that is taking place worldwide to address those challenges, and of the impact that the innovation that this research is fostering could have on the emergence of new CST components and concepts. It is anticipated that these developments will substantially increase the cost-competiveness of commercial CST solutions and reshape the technological landscape of both CST technologies and the CST industry. After an introductory chapter, the next three parts of the book focus on key CST plant components, from mirrors and receivers to thermal storage. The final two parts of the book address operation and control and innovative CST system concepts. - Contains authoritative reviews of CST research taking place around the world - Discusses the impact this research is fostering on the emergence of new CST components and concepts that will substantially increase the cost-competitiveness of CST power - Covers both major CST plant components and system-wide issues
