Preface

Energy storage will be a very important part of the near future and its effectiveness will be crucial for most future technologies. Energy can be stored in several different ways and these differ in terms of the type and the conversion method of the energy. Among those methods; chemical, mechanical, and thermal energy storage are some of the most favorable methods for containing energy. Current energy storage devices are still far from meeting the demands of new technological developments. Therefore, much effort has been put to improving the performance of different types of energy storage technologies in the last few decades. This book explores different methods for energy storage and analyzes the main parameters that affect the utilization of energy storage devices, such as energy density, performance, and cost. Modelling on several hybrid energy storage systems is discussed and this is followed by a proposed control mechanism for energy storage devices. Later chapters include several recent topics such as new advancements in lithium-ion batteries, energy storage systems with redox flow battery, and hydrogen energy storage.
