Analysis of Hydrogen Gas Injection at Various Compositions in an Existing Natural Gas Pipeline

The lack of hydrogen (H 2 ) transportation infrastructure restricts the development H industry. Owing to high investment building specific facilities, using existing natural gas (NG) pipelines transport a blend and NG (H2NG) is viable means approach for large-scale long-time storage. However, variation in thermo-physical properties an H2NG will impact performance pipeline appliances. To address gaps transmission via system context energy consumption, present paper, one-dimensional model proposed predict blended flow real (Shan–Jing I, China). data components were derived from fields. Furthermore, influence fractions on coefficient layout pressurization stations are comprehensively analyzed. In addition, case intermediate injection investigated, effects positions studied. This study serves as useful reference design system. reveals that with increasing fraction, distance between pressure increases. when arrangement original maintained, overpressure occur. Intermediate results inlet subsequent reducing. Using network H2NG, it necessary make appropriate adjustment.
