This book provides a comprehensive understanding of the process of hydrogen production by water splitting, including materials used, methods and instrumentation. It discusses hydrogen production methods with a focus on water splitting (laboratory/industrial scales) followed by its storage and perspectives. It describes all the methods of hydrogen production, i.e., water electrolysis, steam electrolysis, steam reforming, membrane electrolysis and water splitting. The effects of various radiations (ultraviolet, visible, gamma, X-ray and infrared) on hydrogen production are also included.Features: Presents a complete collection of hydrogen generation and discusses the water spitting process in detail. Explores the effects of the radiation of hydrogen generation. Discusses hydrogen generation and storage on a large scale. Presents a future perspective of hydrogen as fuel. Includes future challenges and perspectives to produce hydrogen economically on a large scale. This book is aimed at graduate students and researchers in materials and chemical engineering, radiation science, physics, chemistry and materials science.
