Science and engineering of hydrogen based energy technologies : hydrogen production and practical applications in energy generation Science and Engineering of Hydrogen Based Energy Technologies explores the generation of energy using hydrogen and hydrogen rich fuels in fuel cells from the perspective of its integration into renewable energy systems using the most sound and current scientific knowledge. The book first examines the evolution of energy utilization and the role expected to be played by hydrogen energy technologies in the worlds energy mix not just for energy generation but also for carbon capture storage and utilization. It provides a general overview of the most common and promising types of fuel cells such as PEMFCs SOFCs and direct alcohol fuel cells. The co production of chemical and electrolysis cells as well as the available and future materials for fuel cells production are discussed. It then delves into the production of hydrogen from biomass including waste materials and from excess electricity produced by other renewable energy sources such as solar wind hydro and geothermal. The main technological approaches to hydrogen storage are presented along with several possible hydrogen energy engineering applications. Science and Engineering of Hydrogen Based Energy Technologiess unique approach to hydrogen energy systems makes it useful for energy engineering researchers professionals and graduate students in this field. Policy makers energy planning and management professionals and energy analysts can also benefit from the comprehensive overview that it provides
