Simulation and Analysis of Low Pressure Gas Networks with Decentralized Fuel Injection

Understanding the impact of injecting substitute fuels in the gas distribution network is important in the transition to a low carbon energy supply. A model was developed to identify the effects of decentralized, alternative fuel injections on the steady state operation of the low pressure gas network. A case study was designed to investigate the impact of hydrogen injection on the network compared to the normal operation. The results show the sensitivity of the network pressure distribution and the penetration of hydrogen to the amount and location of hydrogen injection. The study shows that the impact of hydrogen injection can be localized and managed by appropriately choosing the location of injection.
