Enhancing Renewable Energy Utilization: Performance Analysis of Hydrogen-Natural Gas Blending with KSM Static Mixer

Renewable energy and hydrogen energy are closely related, and utilizing renewable energy to produce hydrogen and then transporting and storing the hydrogen can effectively address the uneven geographical distribution of renewable energy. Utilizing in-service natural gas pipelines for the delivery of hydrogen generated from renewable energy sources is a current research hotspot. The flow characteristics of natural gas and hydrogen in the KSM static mixer were analyzed using computational fluid dynamics (CFD) method, and the accuracy of the numerical model in this paper was verified. Based on the research results, effective measures to improve the static mixer have been proposed. The findings provide a theoretical foundation for advancing hydrogen blending in natural gas transportation.
