Metal hydrides hydrogen transport

The fuel and labor costs of metal hydride truck transport are found using the same calculations as those used for gaseous hydrogen transport, adjusting for the number of trips necessary based on the capacities of the vehicles. Therefore, total cost is found in the same way, with the annual capital cost adjusted for the unit differences. 

Because the metallic hydrides release their hydrogen (as H2 gas) when heated or treated with acid, they are being investigated for storing and transporting hydrogen. Both saline and metallic hydrides have the high enthalpy densities desirable in a portable fuel. 

Fernandez and Sanchez [18] investigated the kinetics of hydrogen absorption and desorption by activated magnesium powder (several cycles of hydrogen absorp-tion/desorption at 375°C) using a volumetric technique. They pointed out that for-mation/decomposition of metal hydrides comprises a number of steps taking place in series transport to the surface, dissociation, H chemisorption, surface-... 

Traditionally, hydrogen has heen stored, transported and used in the form of compressed gas or cryogenic liquid. Recharge-ahle metal hydrides have heen proposed as an alternative solid state storage method. A dynamic research community has assembled to explore the scientific basis and evaluate the technology of this hydrogen-metal reaction Metal hydride topics have...
