Heat transfer from/to the metal hydride bed is a
significant factor affecting the performance of metal hydride
storage tanks (MHSTs for short). This study presents a novel
design for metal hydride tank equipped with a heat pipe. The
experimental study explains the use of heat pipe to enhance the
heat transfer in MHST, which built using LaNi4.75Al0.25 as the
storage media and under various hydrogen pressure supplies in
range of 2 to10 bar. This study also presents comparisons
between the two different MHSTs which are designed with and
without heat pipe. Methanol is used as a working fluid inside the
heat pipe. Results show that the usage of heat pipes can be a good
choice to increase hydrogen storing performance in both
absorption and desorption. The absorption time at 10 bar
hydrogen inlet pressure was reduced more than 30%, and the
mass of hydrogen storage increased by 15%
