Summary: This study aims to develop a CFD model capable of predicting the maximum pressure in the blast wave after the rupture of a liquid hydrogen storage tank in a fire. The research concludes that the maximum pressure is generated by a gaseous phase starting shock enhanced by the combustion reaction of hydrogen. The CFD model is updated to account for the cryogenic conditions of LH2 storage.

Summary: Exploration of the thermal performances of composite high-pressure hydrogen storage tanks under fire exposure is crucial for reducing the risk of tank rupture. This study conducted bonfire tests on type III tanks and presented detailed data on tank wall temperature and inner pressure. The results showed the failure pressure limits of the tanks and the consequences of exceeding these limits in fire scenarios.

Summary: Hydrogen embrittlement is a well-known phenomenon in high-strength and storage materials, causing subcritical crack growth, fracture initiation, loss in mechanical properties, and catastrophic failure. The fundamental mechanism of hydrogen embrittlement remains unclear, although various mechanisms responsible for crack development, growth, and fracture have been discussed and reported.

Summary: This study published experimental data on the catastrophic rupture consequences of high-pressure hydrogen storage tanks in fire environments, filling the gap in the verification of traditional theoretical prediction models and numerical simulations. The study analyzed the fireball parameters, fragment characteristics, and blast wave attenuation patterns resulting from tank rupture to reveal the mechanism of high-pressure tank explosion and corresponding characteristics of hydrogen explosion. The proposed methodology and experimental results were of practical importance in ensuring the safety of high-pressure hydrogen storage systems in various applications.

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: A one- and three-dimensional coupled model considering the impact of oil velocity and temperature on the internal heat and mass transfer during the hydrogen desorption process was developed to simulate the large-scale oil-heating type Mg-based hydrogen storage tanks. The simulation results showed that the oil velocity has a significant impact on the hydrogen desorption performance, and a recommended oil velocity of 4 m/s was identified.

Summary: The paper discusses the challenge of temperature rise in hydrogen tanks during fast fill for hydrogen-powered vehicles and proposes an innovative solution of using porous infill to slow down heat transfer. The presence of infill effectively reduces tank wall temperature but increases gas temperature, with the combined effect of internal gas temperature and gas-phase effective thermal conductivity largely determining the final temperature distribution. Further studies on infill design are suggested to seek more effective solutions.

Summary: This study investigates the electronic structure, activation, and kinetic properties of TiZrHfMoNb high-entropy alloy doped with active metals. The results demonstrate that electron transfer occurs between active metal atoms and other metal atoms, leading to the destabilization of the surface oxide and improved activation performance. It is believed that this electron transfer process optimizes the electron density of interstitial sites, allowing for increased hydrogen storage capacity. This research provides new insights into the hydrogen storage properties of high-entropy alloys and highlights the potential for further increasing the storage capacity through doping.

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.
