Many developed countries around the world are currently competing to fid low-cost, sustainable and clean energy sources. To replace conventional energy sources such as (oil, coal, etc.) for several reasons. mainly, because of the negative environmental impact of the Greenhouse Gas (GHG) emission problem. Also, these resources will deplete soon. As a result, seeking for a better replacement of fossil fuels either by converting to electric vehicles or by using other possible renewable energy sources with low (GHG) emissions is essential. Hydrogen is one of the primary potential future alternatives of current automotive petroleumrelated due to its high mass-energy ratio and abundance since it can be obtained from a broad spectrum of sources and by various techniques, such as anaerobic digestion from organic materials, rendering it a prospective target for safe and renewable energy. Hydrogen fuel stations are predicted to have a signifiant impact on the implementation of hydrogen as a fuel substitution on the worldwide fuel market, especially for heavy transportation. Th primary objective of this innovative station branch is not only to promote the idea of hydrogen fuel on the vehicle fuelling industry but also to enhance the advancement of hydrogen fuel facilitieswhile minimizing the danger to the investor. Thre are, though, some areas that need to be investigated with such drop-in facilities as storage and delivery mechanisms which this study covers. Th key idea of such a system is to provide a safe, affrdable and accessible car fuel source equivalent to conventional vehicle fuel on the industry, whether it is renewable. Th primary goal of this research is to develop a secure, flxible and environmentally friendly hydrogen fueling facility, this design is regarded to be cost-effient compared to other designs by at least 48 percent. Furthermore, this design showed encouraging signs concerning safety procedures and hazard evaluation where is ranked 6.8 on average out of 25 in the FMEA review assuring it’s safe further

-The basic understanding of gas diffusion and technology to predict the diffusion phenomena are needed to prepare against a disaster of leakage of natural gas and to design better consistent and reliable gas supply system in enclosure. The experimental results of British Gas Technology Co. are used in present study as a reference of theoretical study using CFD. The present results of 2D CFD analysis for mass flow rate of nozzle release show good agreement with experimental results within 2.6 % error. 3D CFD analysis for the characteristics of natural gas diffusion in enclosure with various ventilation patterns also gives reasonable agreement with experimental results.

“…Their results indicated the optimal positions for hydrogen sensors and ventilation. Liu et al [13] conducted a CFD simulation on highpressure hydrogen released from storage tanks; furthermore, factors such as wind speed, ambient temperature, leak location, leak hole diameter, and obstructions on hydrogen diffusion were evaluated. Dadashzadeh et al [14] summarized their results on the dispersion behavior of hydrogen gas from a hydrogen fuel cell car in an enclosed area and provided safety measures for using hydrogen in ventilation conditions.…”

Hydrogen is an alternative to conventional heavy marine fuel oil following the initial strategy of the International Maritime Organization (IMO) for reducing greenhouse gas emissions. Although hydrogen energy has many advantages (zero-emission, high efficiency, and low noise), it has considerable fire and explosion risks due to its thermal and chemical characteristics (wide flammable concentration range and low ignition energy). Thus, safety is a key concern related to the use of hydrogen. Whereas most previous studies focused on the terrestrial environment, we aim to analyze the effects of the ship’s motion on hydrogen dispersion (using commercial FLUENT code) in an enclosed area. When compared to the steady state, our results revealed that hydrogen reached specific sensors in 63% and 52% less time depending on vessel motion type and direction. Since ships carry and use a large amount of hydrogen as a power source, the risk of hydrogen leakage from collision or damage necessitates studying the correspondence between leakage, diffusion, and motion characteristics of the ship to position the sensor correctly.
