Molten Salts: Applications, Challenges, and Future Prospects in Energy Systems provides a comprehensive exploration of one of the most important classes of high-temperature functional materials used in modern science and engineering. Combining fundamental principles with practical engineering applications, this book presents a clear and interdisciplinary treatment of molten salt technologies and their rapidly expanding role in sustainable energy systems.The book begins with the chemistry, classification, thermodynamic behavior, and physicochemical properties of molten salts before examining transport phenomena, heat transfer, electrochemistry, corrosion mechanisms, materials compatibility, and purification techniques. These foundational concepts are then connected to real-world engineering applications, enabling readers to understand how molten salts function in demanding industrial environments.A major focus of the book is the application of molten salts in thermal energy storage, concentrated solar power, advanced nuclear reactors, molten salt reactors, hydrogen production, industrial electrochemistry, high-temperature batteries, metallurgy, and chemical manufacturing. Each topic is supported by discussions of engineering design, operational principles, performance characteristics, safety considerations, and current technological developments. The book also examines economic challenges, commercialization pathways, environmental sustainability, and regulatory issues that influence the large-scale deployment of molten salt technologies.Recognizing the rapid evolution of the field, the book explores emerging innovations including artificial intelligence, machine learning, digital twins, autonomous monitoring, predictive maintenance, advanced computational modeling, and intelligent process optimization. These technologies are transforming the design, operation, and reliability of future molten salt systems while supporting the transition toward carbon-neutral energy infrastructure.Designed for graduate students, researchers, faculty members, practicing engineers, and industry professionals, this volume combines scientific rigor with practical insight. Numerous illustrations, engineering examples, review questions, references, and future research perspectives make it suitable as both a graduate-level textbook and a professional reference.By integrating chemistry, materials science, thermal engineering, electrochemistry, and energy systems into a unified framework, this book demonstrates how molten salts are becoming enabling materials for next-generation technologies. It offers readers a thorough understanding of both the scientific foundations and the engineering challenges of molten salt systems while highlighting their critical role in the future of sustainable energy, advanced manufacturing, and intelligent industrial infrastructure.
