Thermal performance analysis of a metal hydride reactor encircled by a phase change material sandwich bed

Review of thermal management technology for metal hydride reaction beds

“…With the same total weight of MH and the PCM, the MHR with the addition of PCMs inside and outside the MHB had a better heat transfer rate, in which the MHR with PCMs wrapped by cylindrical tubes had the largest improvement in hydrogen uptake time of 58.1%. Alqahtani et al 198 and Ye et al 199,200 developed sandwich MH-PCM structures, respectively, as shown in Fig. 12c and d.…”

Parametric study of a metal hydride reactor with phase change materials and heat pipes

“…We consider the same assumptions considered in the literature 28,29,36 to establish the governing equations for the MHR and the PCM domains.…”

Thermal Energy Storage technologies for the optimal management of metal hydride hydrogen storage systems

“…Starting from the experiences of the authors about PCM [12] and MH [4] [13] applications and being inspired by other studies that have already investigated this concept of coupling TES and MH for their optimal thermal management [14] (both thermochemical [15] and latent heat energy storage [16]) , this study proposes a simplified modelling procedure for the sizing and the techno-economic feasibility assessment of the coupling of MH and PCM (starting from materials main thermodynamic properties) for their optimal thermal management and minimization of OPEX. Such approach was applied to a 1 MW PEM electrolyser coupled to a 1 MW PV rooftop (with Hydrogen used in an industrial process), sizing PCM system that could guarantee a proper management of the MH storage without any support by a compressor also in order to investigate which could be the cost that PCM should target to make this integrated PCM+MH storage techno-economically viable.…”
