Summary: Hydrogen is becoming increasingly important in the clean energy transition, and the safe and high-density storage of hydrogen is crucial in the hydrogen ecosystem. Metal hydride storage appears to be superior to compressed gas storage, but thermal management is a challenge that needs to be addressed. This study provides a comprehensive review of heat transfer, thermal management techniques, and studies on the thermal management of metal hydride tanks in integrated systems with fuel cells and/or electrolyzers.

Summary: This study investigates the performance of a hybrid energy storage system composed of a metal hydride tank and a lithium-ion battery pack, aiming to replace the conventional battery pack in a plug-in fuel cell electric scooter. The concept is to use the endothermic hydrogen desorption in metal hydrides to cool the battery pack during operation. Numerical analysis is conducted to assess the thermal management capabilities of the proposed solution under realistic operating conditions. The results demonstrate that the hybrid energy storage system effectively controls the battery pack temperature and increases the on-board storage energy density.

Summary: The thermal management between the metal hydride (MH) tank and the proton exchange membrane fuel cell (PEMFC) has been investigated. A lumped parameter model for the PEMFC-MH system has been developed and validated to predict the system performance. The results indicate the feasibility of using waste heat from the PEMFC to heat the MH bed. The effect of valve's opening degree on system performance has been studied and shown to be an effective control measure in thermal management to improve energy efficiency of the PEMFC-MH system.

Summary: This study parameterized, experimentally validated, and applied a model to accurately simulate the absorption and desorption processes in a double-layered annulus metal hydride tank. The results showed that the hydrogen absorption performance can be enhanced by increasing initial porosity and decreasing initial particle radius, temperature, and hydrogen concentration. On the other hand, hydrogen desorption performance mainly depends on increasing the hydrogen concentration.

Summary: The thermal coupling system (TCS), which transfers the heat generated by proton exchange membrane fuel cell (PEMFC) to a metal hydride (MH) tank, has been proven to be beneficial in terms of system compactness and capital cost. However, there has been limited attention given to regulating hydrogen desorption to increase the efficiency of hydrogen-to-power/heat (hh-p), especially in distributed energy systems (DES) that combine power and heat. This study proposes an energy saving control strategy for a TCS applied in a DES, aiming to increase the hh-p while satisfying the cosine-form hydrogen demand. A threshold temperature is introduced to represent the maximum hh-p, and a prediction framework for the threshold temperature is proposed based on its functional relationship with five operation parameters and the Fourier decomposition method (FDM). The study also discusses the operation strategy of a two-tank TCS and suggests supplying the rated hydrogen demand using both MH tanks to increase hydrogen utilization and extend the supply duration.

Summary: High-temperature metal hydride (MH), such as magnesium hydride, is seen as a promising technology for hydrogen storage. However, low hydrogen absorption rate and reactor capacity are major challenges. This study proposes a novel MH reactor configuration to improve hydrogen absorption performance through CFD simulation and sensitivity analysis. Increasing the number of air passages significantly reduces charging time, and a recommended configuration using four air passages achieves approximately 30 minutes loading time.

Summary: Various thermal management methods are widely adopted in the metal hydride (MH) system to release the thermal effect and obtain acceptable hydrogen storage performance. In this study, an axisymmetric numerical model for a simple MH system without a heat exchanger (HE) has been established and validated to study the system performance during dehydriding. The coiled-tube heat exchanger (CTHE) shows more obvious impact than the phase change material heat exchanger (PCMHE) in improving the performance of the MH system during dehydriding.

Summary: The configuration of phase change materials in hydrogen storage tanks affects the storage performance. Sandwiched MH-PCM units have faster heat transfer and reaction rates due to larger transfer area and smaller thermal resistance. The amount of PCM affects the reaction fraction and can slightly impact absorption and desorption rates when reduced within sufficient limits.

Summary: This study investigates the process parameters that affect the improvement of hydrogen storage material properties. The thermal conductivity of the storage materials has been improved to accelerate the hydrogen charge/discharge processes and obtain the required hydrogen at desired flow rates in a short time. The experimental results show that coating the storage material with copper increases heat transfer, reduces the hydrogen charging time, and improves stable discharge time in the metal hydride reactor.
