Summary: TiFe intermetallic compound is extensively studied due to its low cost, good volumetric hydrogen density, and the ability to tailor hydrogenation thermodynamics through elemental substitution. Increasing titanium content and substituting manganese can improve hydrogen storage performance, with titanium-rich alloys showing enhanced storage capacities as long as a limited amount of beta-Ti is formed.

Summary: Hydrogen precooling is an effective method for fuel cell vehicles, and the estimation of cooling demand is crucial for its configuration and energy analysis. This paper establishes a thermodynamic model to investigate the impact of pipelines on the precooling performance. The results show that flow resistance and heat dissipation through the pipelines have significant effects on the cooling demand.

Summary: The cascade storage system has lower energy consumption compared to the one-buffer system, resulting in approximately 34% energy savings. Total energy consumption in the three-cascade storage system increases nearly linearly with the high-pressure tank pressure, while showing concave curve trends with the increase of low-pressure and medium-pressure levels. The charging sequence from low-pressure to high-pressure tanks decreases total operation energy consumption.

Summary: This paper investigates the performance of a hydrogen refueling system that consists of a polymer electrolyte membrane electrolyzer integrated with photovoltaic arrays, and finds that the efficiency of the station significantly increases when the electric grid empowers the system. The exergy cost of hydrogen production varies from 30% to 4 times higher in different scenarios, with the on-grid station without energy storage having the highest exergy cost.

Summary: In recent decades, the impacts of climate change due to greenhouse gas emissions have become more severe, prompting international authorities to seek green solutions for sustainable economic development. One such solution is the reduction of fossil fuel usage in the transportation sector, with hydrogen emerging as a promising alternative due to its potential as an emission-free fuel when produced using renewable energy sources. However, there are several barriers to overcome, including production costs and the lack of distribution and storage infrastructure. This study proposes a multi-hub configuration for hydrogen production, combining on-site PV-powered electrolysis and centralized steam methane reforming. The results show that the size of the refueling station significantly affects economic performance, with larger stations offering greater benefits such as a reduction of up to 40% in the Levelized Cost of hydrogen. The synergistic effects of SMR and electrolyzer enable limited CO2 emissions per unit mass of hydrogen, and interconnecting multiple stations can further enhance environmental benefits.

Summary: Hydrogen has the potential to be a promising energy carrier, particularly for decarbonizing the economy and the transport sector. Fuel Cell Electric Vehicles (FCEVs) can reduce air pollution and greenhouse gas emissions when powered by hydrogen produced from renewable sources and accessed through a widespread network of refueling stations. This study analyzed the sizing and financial analysis of a hydrogen refueling station supplied with excess electrical energy from a 10 MW wind park. The results showed that a wind-powered refueling station can be a viable solution when sized appropriately.

Summary: The effects of different factors on hydrogen leakage diffusion were studied through numerical simulation, using Ningbo's seaport hydrogen refueling station as the research object. The presence or absence of obstacles significantly influences the leakage angle's impact on hydrogen leakage. Wind direction can greatly affect hydrogen leakage, with downwind and sidewind accelerating discharge and reducing risk. Temperature and humidity have little effect on hydrogen diffusion.
