Design and performance analysis of an annular metal hydride reactor for large-scale hydrogen storage applications

Experimental and numerical study of temperature evolution and hydrogen desorption process on an amorphous alloy Mg50Ni50

“…The proposed model, which describes the H 2 diffusion through the hydride bed, is based on energy balances for the hydrogen-heating model, mass balances for H 2 diffusion model, and heat exchanger metal hydride bed model. In our case, adsorption kinetics depends on pressure is taken into consideration to valid the proposed mathematical model [ [13] , [14] , [15] , [16] ].…”

“…In the extensive exploration of Mg-based alloys conducted to date, despite occasional conflicting results in certain studies, specific elements have emerged as particularly promising due to their notable hydrogen storage capacity. Several experimental and theoretical investigations have delved into the hydrogen desorption characteristics of various Mg-based alloys [ [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] ]. Notably, Orimo et al [ 21 ] focused on examining the H 2 storage properties of the Mg 50 Ni 50 alloy in its amorphous state.…”

State of the Art in Development of Heat Exchanger Geometry Optimization and Different Storage Bed Designs of a Metal Hydride Reactor

“…Prasad J. S. and Muthukumar P. [ 161 ] considered three configurations of annular metal hydride reactors. The first configuration and the second configuration differed in the heat transfer fluid’s flow direction, and the third configuration was the same as the second, but with the addition of radial fins without any specific geometry ( Figure 21 a).…”

Review of thermal management technology for metal hydride reaction beds

“…27 This method does not change the structure of the MHB and it is a simple and fast heat exchange device, which makes it useful both directly as a basic tool and in combination with other thermal management technologies. 28 As compared to the MHR without the cooling jacket, the effective heat transfer coefficient of the MHR with the external cooling jacket may be raised from 5.5 29 and the bed temperature peak is lower, which would enhance the hydrogen absorption rate and shorten the absorption time. 30 The heat transfer effect of the system can be impacted by the uid temperature 27,31 and jacket parameters.…”
