The issue of fulfilling the growing worldwide energy demand while minimizing environmental consequences through the exploration of hydrogen fuel's potential as a sustainable energy solution. Hydrogen, produced through electrolysis, offers a promising way to decrease carbon emissions without contributing to climate change. The research considers the complexities of hydrogen transportation, recognizing the need for specialized infrastructure due to hydrogen's high diffusivity. The primary emphasis of the study revolves around incorporating hydrogen into the existing natural gas pipeline system as a financially viable option. The research utilizes tools like the General Algebraic Modeling System (GAMS) and design expert tools to identify the most suitable blend ratios of hydrogen and natural gas for secure and effective transportation. The analysis also evaluates the economic implications of different blend proportions, including the costs associated with modifying the infrastructure. Through computational analysis, the study quantifies the energy and cost requirements for compressing and transporting the gas blends, considering variables such as pipeline diameter, hydrogen injection ratio, and flow rate. The findings reveal that an optimal mix, comprising a 20% hydrogen injection rate, a flow rate of 616.459 million standard cubic feet per day, and a 36-inch pipeline diameter, results in the lowest energy use of 13831.097 HP and transportation cost of 314.673 million $/yr., with a desirability of 87.1%. This optimal configuration promotes a balanced approach to energy security, accessibility, and sustainability.
