Traditionally, energy is associated with its collection and conversion, as well as its distribution and consumption. As the production of energy from intermittent renewable sources, such as solar and wind, increases in the context of achieving climate neutrality, the need for energy storage increases in terms of the quantity of stored energy and the required storage time. As depicted on the cover of the book, energy storage is a new emerging scientific and technologically applied field that connects the main activities of energy collection, distribution, and consumption.

This book presents the basic concepts and principles of operation of the main methods of energy conversion and storage in various forms, such as thermal, mechanical, electrical, electrochemical, and chemical. For a better understanding of the different energy storage technologies, the book includes many useful and explanatory examples, problems, and solutions. The book is intended for undergraduate students, graduate students, professional engineers, and scientists working in the field of energy, as well as doctoral students with the necessary scientific background who would like to have a better understanding of these processes from an engineering perspective.
