Summary

The paper presents a numerical model to evaluate the dynamic behaviour of heat and mass transfer in metal hydride energy systems. At first, with reference to each metal hydride reactor (i.e. heat exchanger filled with metal hydride), both the equations which describe the hydrogen absorption-desorption and the heat transfer are derived. Then, the "core" of metal hydride energy systems, i.e. coupled metal hydride reactors, has been considered and the complete numerical modelling has been carried out. The complete model has been implemented by assembling the dynamic model of heat and mass transfer between two coupled hydrides, previously developed by the author, with the model developed to describe all feasible cyclic operations occurring in metal hydride energy systems, such as heat pumps, temperature upgrading devices, refrigeration plants, etc. It seems that a reasonable compromise between accuracy and simplicity, has been attained.
