Abstract
present study evaluates the important -role that can be played
the process of energy storage . Energy storage in the form of
drogen presents many advantages over the other forms of energy
s-orage . This work studies the storage of hydrogen in a metal hydride
A convective bed model is assumed and its mathematical
Formulation is developed to simulate the dynamic phenomenon of
hydrogen discharge. The partial differential equations that describe
both mass and heat transfer phenomena encountered in the model are
solved using an implicit finite difference technique . A computer
code is developed to obtain the temperature distribution along the
bed length the hydrogen — to — metal atom ratio and the total
accumulated hydrogen at any time level
Three metal hydrides are used in this study and their performance
during the discharging process is established . These metal hydrides
are : La Nis H6 t Fe Ti Hl .6 and M92 Ni H4 .
Using the developed computer code , major factors affecting the rate
of hydrogen release,from the used metal hydrides , are studied
and found to be ordered according to their potential impact on
hydrogen discharging rate as : inlet hydrogen temperature , bed
pressure , inlet hydrogen mass flow rate , bed length and bed void
fraction This parametric analysis can be utilized to get the
optimum conditions for operation .
