Hydrogen is becoming more important as a source of energy for many applications. Hydrogen storage is a challenge task in developing this technology. There are many methods for hydrogen storage. The most common method to store hydrogen is complex hydrides. In this study, the analytical hierarchical process (AHP) is used to select the best material for hydrogen storage device. The model is built using four criteria, including: mechanical properties, physical properties, chemical properties and cost. LiBH4, NaAlH4, LiNH2, Mg4NiPd, KAlH4, Mg (AlH4), Li3AlH6, Na2LiAlH6 were used as alternatives to select among them. The results show that Mg4NiPd is the best material. Both inconsistency and sensitivity analysis were done and showed that model is robust

Air-to-air fixed plate enthalpy membrane exchanger is considered one of the equipment used in energy recovery services. Thermal performance of air-to-air energy recovery ventilator is examined numerically using a 3D CFD simulation. Air flow inside the exchanger is tested using four numerical turbulence models: Standard k-ε, k-ε renormalization group (RNG), k-ε realizable and k-ω shear-stress transport (SST) models. The adopted heat and mass exchange element within the ventilator (membrane) is a thin 98 µm porous 60 gsm Kraft paper. A user defined function (UDF) has been developed to enable the CFD model to estimate amounts of mass exchanged between the two sides of the membrane. Grid dependency study is conducted and results have shown that a perpendicular distance of 50 m or less from the membrane surface would result in a negligible variation in the ERV thermal effectiveness. The validated CFD model and UDF code against experimental measurement resulted in a maximum difference in thermal effectiveness of 3.6%. Results have shown that the SST k-ω turbulence models under enhanced wall treatment showed more sensitivity to flow at all Re values when compared with the k-ε simulated models.
