Blending hydrogen with natural gas in distribution networks: technical and safety considerations
Original language description
This review presents a comprehensive assessment of hydrogen blending into natural gas (NG) networks as a transitional strategy to support the decarbonization of energy systems. The review addresses key technical, environmental, and operational aspects of hydrogen-enriched natural gas (HENG). It covers the motivation for hydrogen blending, the role of hydrogen in managing renewable energy intermittency, its impact on gas grid dynamics, flammability and explosion behavior, leakage and safety concerns, and end-use appliance compatibility. The findings confirm that hydrogen blending up to 20 % is technically feasible and can reduce greenhouse gas emissions while using existing infrastructure. However, success depends on updated standards, advanced monitoring technologies, and coordinated regulatory frameworks. The review concludes with a synthesis of knowledge gaps and recommendations for future research and deployment.
