Many developed countries around the world are currently competing to find 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 significant impact on the implementation of hydrogen as a fuel substitution on the worldwide fuel market, especially for heavy transportation. The 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 facilities while minimizing the danger to the investor. There are, though, some areas that need to be investigated with such drop-in facilities as storage and delivery mechanisms which this study covers. The key idea of such a system is to provide a safe, affordable and accessible car fuel source equivalent to conventional vehicle fuel on the industry, whether it is renewable. The primary goal of this research is to develop a secure, flexible and environmentally friendly hydrogen fueling facility, this design is regarded to be cost-efficient 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.

Facing global warming and recent bans on the use of diesel in vehicles, there is a growing need to develop vehicles powered by renewable energy sources to mitigate greenhouse gas and pollutant emissions. Among the various forms of non-fossil energy for vehicles, hydrogen fuel is emerging as a promising way to combat global warming. To date, most studies on vehicle carbon emissions have focused on diesel and electric vehicles (EVs). Emission assessment methodologies are usually developed for fast-moving consumer goods (FMCG) which are non-durable household goods such as packaged foods, beverages, and toiletries instead of vehicle products. There is an increase in the number of articles addressing the product carbon footprint (PCF) of hydrogen fuel cell vehicles in the recent years, while relatively little research focuses on both vehicle PCF and fuel cycle. Zero-emission vehicles initiative has also brought the importance of investigating the emission throughout the fuel cycle of hydrogen fuel cell and its environmental impact. To address these gaps, this study uses the life-cycle assessment (LCA) process of GREET (greenhouse gases, regulated emissions, and energy use in transportation) to compare the PCF of an EV (Tesla Model 3) and a hydrogen fuel cell car (Toyota MIRAI). According to the GREET results, the fuel cycle contributes significantly to the PCF of both vehicles. The findings also reveal the need for greater transparency in the disclosure of relevant information on the PCF methodology adopted by vehicle manufacturers to enable comparison of their vehicles’ emissions. Future work will include examining the best practices of PCF reporting for vehicles powered by renewable energy sources as well as examining the carbon footprints of hydrogen production technologies based on different methodologies.
