Hydrogen Energy

Due to global energy and climate problems, efficient, clean and economical technologies that increase the diversity of energy sources are gaining importance. This requires significant innovations in energy generation, conversion, distribution, storage and end-use. Hydrogen energy is an excellent potential solution to meet the global energy demand. Hydrogen power can enable a world where our emissions and other environmental damage issues are eliminated or minimized, and our demand for affordable, efficient, reliable and clean energy is met. To fully understand “hydrogen energy”, it is necessary to grasp all aspects of hydrogen, from its characteristics to its difference from available fuels. Therefore, this chapter provides information on the properties of hydrogen and its comparison with other fuels and energy sources. In addition, hydrogen production, storage and end-use methods are described. And at the end of this chapter, the research directions and methods needed for more sustainable energy systems are given.
