The book explores the role of energy storage systems in energy networks with large-scale renewable energy systems such as solar, wind, hydropower and tidal energy. Some of the storage scenarios included in the book include various energy storage technologies, including batteries, super-capacitors, hydrogen, fuel cells, desalination, compressed air energy storage, and heat exchangers. The theory, practices, and applications of storage systems in conjunction with renewable energy sources are also included. Plenty of presentations and analyses of particular case studies, best practices, technical solutions, and techno-economic evaluations are also covered. This book is a perfect reference for researchers, practitioners, professionals, and graduate students interested in the most recent research on energy storage devices.
