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: 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.

Summary: This study simulates the dispersion of hydrogen leakage and the minimum safe distance of explosion in a mobile hydrogen refueling station. A 3D full-scale geometry is established and experimental data validates the numerical models. The effects of ventilation scenarios and ambient wind on hydrogen volume and diffusion distance are analyzed. The investigation provides valuable insights for evaluating and preventing hydrogen leakage accidents in mobile hydrogen refueling stations.

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: With the increasing number of hydrogen fuel cell vehicles, the installation of necessary infrastructure such as hydrogen refueling stations (HRSs) is crucial. However, the use and storage of high-pressure gaseous hydrogen in conventional HRSs have limitations and safety risks. Ammonia, with its high storage capacity and ability to be stored as a liquid, is considered a potential solution as a carrier for hydrogen. However, ammonia is toxic and can be fatal if accidentally exposed to humans. Therefore, this study aims to develop a process and safety design for HRSs using ammonia as the hydrogen carrier.

Summary: This study investigates hydrogen diffusion in different wind conditions, finding that constant wind velocity and variable wind velocity have different effects on hydrogen diffusion. Variable wind velocity may lead to a more dangerous situation with a larger flammable gas cloud volume. Additionally, wind conditions have a significant impact on the distribution of hydrogen mass fraction along the radial direction.
