Optimization of Hydrogen Blending in Natural Gas Networks for Carbon Emissions Reduction
2023 American Control Conference (ACC), 2023 We present an economic optimization problem for allocating the flow of natural gas and hydrogen blends through a large-scale transportation pipeline network. Physical flow of the gas mixture is modeled using a steady-state relation between pressure decrease and flow rate, which depends on mass concentration of the constituents as it varies by location ...
