Energy Storage Systems Volume Ii

Energy Storage Systems theme is a component of Encyclopedia of Energy Sciences, Engineering and Technology Resources which is part of the global Encyclopedia of Life Support Systems (EOLSS), an integrated compendium of twenty one Encyclopedias. The Theme is organized into six different topics which represent the main scientific areas of the theme: The first topic, Rationale of Energy Storage and Supply/Demand Matching is devoted to the discussion of essential concepts and the most important aspects of the optimization, establishment and operation of energy storage systems based on six cases as examples. The succeeding four topics are Storage of Thermal Energy; Mechanical Energy Storage; Storage of Electrical Energy; Storage of Chemical Energy and Nuclear Materials. Each of these consists of a topic chapter emphasizing the general aspects and various subject articles explaining the back ground, theory and practice of a specific type of energy storage of that topic. The last topic is transport of energy with emphasis on hydrogen as future energy carrier. It contains detailed review of other modes of energy transport and discussion of environmental effects. Fundamentals and applications of characteristic methods are presented in these volumes. These two volumes are aimed at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

Electricity from renewable sources of energy is plagued by fluctuations (due to variations in wind strength or the intensity of insolation) resulting in a lack of stability if the energy supplied from such sources is used in ‘real time’. An important solution to this problem is to store the energy electrochemically (in a secondary battery or in hydrogen and its derivatives) and to make use of it in a controlled fashion at some time after it has been initially gathered and stored. Electrochemical battery storage systems are the major technologies for decentralized storage systems and hydrogen is the only solution for long-term storage systems to provide energy during extended periods of low wind speeds or solar insolation. Future electricity grid design has to include storage systems as a major component for grid stability and for security of supply. The technology of systems designed to achieve this regulation of the supply of renewable energy, and a survey of the markets that they will serve, is the subject of this book. It includes economic aspects to guide the development of technology in the right direction. Provides state-of-the-art information on all of the storage systems together with an assessment of competing technologies Features detailed technical, economic and environmental impact information of different storage systems Contains information about the challenges that must be faced for batteries and hydrogen-storage to be used in conjunction with a fluctuating (renewable energy) power supply

Thermal, Mechanical, and Hybrid Chemical Energy Storage Systems provides unique and comprehensive guidelines on all non-battery energy storage technologies, including their technical and design details, applications, and how to make decisions and purchase them for commercial use. The book covers all short and long-term electric grid storage technologies that utilize heat or mechanical potential energy to store electricity, including their cycles, application, advantages and disadvantages, such as round-trip-efficiency, duration, cost and siting. Also discussed are hybrid technologies that utilize hydrogen as a storage medium aside from battery technology. Readers will gain substantial knowledge on all major mechanical, thermal and hybrid energy storage technologies, their market, operational challenges, benefits, design and application criteria. Provide a state-of-the-art, ongoing R&D review Covers comprehensive energy storage hybridization tactics Features standalone chapters containing technology advances, design and applications

ENERGY STORAGE Written and edited by a team of well-known and respected experts in the field, this new volume on energy storage presents the state-of-the-art developments and challenges in the field of renewable energy systems for sustainability and scalability for engineers, researchers, academicians, industry professionals, consultants, and designers. The world’s energy landscape is very complex. Fossil fuels, especially because of hydraulic fracturing, are still a mainstay of global energy production, but renewable energy sources, such as wind, solar, and others, are increasing in importance for global energy sustainability. Experts and non-experts agree that the next game-changer in this area will be energy storage. Energy storage is crucial for continuous operation of power plants and can supplement basic power generation sources over a stand-alone system. It can enhance capacity and leads to greater security, including continuous electricity supply and other applications. A dependable energy storage system not only guarantees that the grid will not go down, but also increases efficacy and efficiency of any energy system. This groundbreaking new volume in this forward-thinking series addresses all of these issues, laying out the latest advances and addressing the most serious current concerns in energy storage. Whether for the veteran engineer or the student, this latest volume in the series, “Advances in Renewable Energy,” is a must-have for any library. This outstanding new volume: Is practically oriented and provides new concepts and designs for energy storage systems, offering greater benefit to the researcher, student, and engineer Offers a comprehensive coverage of energy storage system design, which is also useful for engineers and other professionals who are working in the field of solar energy, biomass, polygeneration, cooling, and process heat Filled with workable examples and designs that are helpful for practical applications, also offers a thorough, novel case study on hybrid energy systems with storage Is useful as a textbook for researchers, students, and faculty for understanding new ideas in this rapidly emerging field

This book will provide the technical community with an overview of the development of new solutions and products that address key topics, including electric/hybrid vehicles, ultrafast battery charging, smart grids, renewable energy (e.g., solar and wind), peak shaving, and reduction of energy consumption. The needs for storage discussed are within the context of changes between the centralized power generation of today and the distributed utility of tomorrow, including the integration of renewable energy sources. Throughout the book, methods for quantitative and qualitative comparison of energy storage means are presented through their energy capacity as well as through their power capability for different applications. The definitions and symbols for energy density and power density are given and relate to the volume and weight of a given system or component. A relatively underdeveloped concept that is crucial to this text is known as the theory of Ragone plots. This theory makes possible the evaluation of the real amount of energy that can possibly release out of a given system, with respect to the level of power dependency chosen for the discharge process. From systems using electrochemical transformations, to classical battery energy storage elements and so-called flow batteries, to fuel cells and hydrogen storage, this book further investigates storage systems based on physical principles (e.g., gravitational potential forces, air compression, and rotational kinetic energy). This text also examines purely electrical systems such as superconductive magnets and capacitors. Another subject of analysis is the presentation of power electronic circuits and architectures that are needed for continuously controllable power flow to and from different storage means. For all systems described, the elementary principles of operation are given as well as the relationships for the quantified storage of energy. Finally, Energy Storage: Systems and Components contains multiple international case studies and a rich set of exercises that serve both students and practicing engineers.
