As the field of hydrogen fuel is fast-growing there is a need for updated knowledge of this subject. This book covers recent developments in solar hydrogen production such as solar thermal and solar photo-assisted methods. It provides an engineering approach to the analysis of solar hydrogen including solar photo-assisted hydrogen and solar thermal hydrogen production. Other topics associated with solar hydrogen are covered including storage and transportation, risk analysis and detection of hydrogen, techno-economic analysis and sustainable assessment, and LCA/environmental impact analysis.
