Greening the gas network - The need for modelling the distributed injection of alternative fuels

A numerical simulation of a regional-scale natural gas transmission system is performed where green gasses are injected into the grid. In the case of hydrogen blending, the maximum quantity of injectable hydrogen in each node is calculated to achieve a 10% blend as an upper constraint. In conclusion, the impact of green fuels injection in the gas network on the resulting natural gas quality (i.e., Wobbe index, gas gravity, higher heating value) is investigated thoroughly.
