ABSTRACT

Hydrogen and fuel cell technologies have strong potential to play a significant role in the new energy system that must be defined in the coming years. A future hydrogen based society in which hydrogen is the primary energy vector will soon become a reality. Hydrogen is viewed as an energy storage solution for many of the energy problems over the world. There are currently three main technologies for storing hydrogen as: compressed gas, liquefied cryogenic fluid, or solid in a metal hydride [2]. For automotive applications, most car manufacturers have decided to not use liquid hydrogen as an embedded storage mostly due to the high energy cost of hydrogen liquefaction, which today can add as much as 50% to the cost of H2 [3-5]. The high-pressure storage [300-750bar] causes security and societal acceptance problems. Otherwise, the metal hydride storage offers the possibility to operate at lower pressure [1-10bar] with a very good energy efficiency. The metal hydrides provide a safe way of handling hydrogen. Therefore, an important number of studies has been carried out to develop this technology in the last years. The absorption and desorption process in porous media of hydride material are the principal issue for the operation of this system. In this work, a general review on metal hydrides using both simulation and experimental processes was presented. TiFeMn and otherhydrides synthesized by mechanical alloying, structure, microstructure, composition and morphology were also investigated.
