Abstract Metal hydrides are regarded as one of the most attractive options for thermal energy storage (TES) materials concentrated solar applications. Improved performance such systems is vitally determined by effectiveness heat exchange between metal hydride and transfer fluid (HTF). This paper presents a numerical study supported experimental validation on magnesium reactor fitted with helica...

Here, the authors report results of their study on key characteristics microscale periodic Ni-Mg-Ni-Mg film structures as metal-hydride hydrogen accumulators, namely, microstructure, phase state, operation temperatures and rate sorption/desorption processes, complete reversible mass content hydrogen, enthalpy metal hydrides’ phase-formation. The has shown that hydride-formation films can be sat...
