Abstract
In response to global decarbonization imperatives and the rapid advancement of hydrogen technologies, the transmission of hydrogen and hydrogen-natural gas mixtures through existing pipeline infrastructure has emerged as a critical area of investigation. This paper presents a comprehensive analysis of energy transmission dynamics in pipelines conveying pure hydrogen and natural gas-hydrogen mixtures, with particular emphasis on both constant energy stream and isovolumetric flow conditions. The study systematically evaluates the impact of hydrogen admixture on critical energy transmission parameters, including volumetric and gravimetric energy density, calorific value, and hydraulic transport characteristics. Our findings demonstrate that while hydrogen blending inevitably reduces the energy density of the transported medium, at lower concentrations (typically below 20% by volume) it may yield favorable hydraulic effects, notably manifested through reduced pressure gradients and improved flow characteristics. The analytical framework incorporates rigorous thermodynamic modeling and economic assessment, examining various hydrogen blend ratios and their consequent effects on pipeline throughput capacity and operational expenditures. A key focus of this investigation involves comparative analysis of hydrogen and methane (as the principal constituent of natural gas) energy parameters under volumetric constraints. The results indicate that maintaining constant energy flow conditions may effectively negate the hydraulic advantages conferred by hydrogen admixture. Article presents detailed hydraulic simulations for multiple hydrogen-natural gas blend scenarios, contrasting performance under both constant volumetric flow and constant energy flow regimes. The analysis provides critical insights for infrastructure operators and policymakers considering the transition to hydrogen-enriched gas transmission systems.
