A society with interconnected energy sectors may be a contributing factor to reduce carbon dioxide emissions, while simultaneously meeting the increasing demand for electric energy. This study investigates the possibilities to link a sea-based wind farm with hydrogen gas production in addition to serving as a support function to a transmission systems operator. Using a custom-built model, this interconnected system is simulated for different scenarios where the wind farm, electrolyser and the balanced power market are observed. The model takes into account the economic potential and the different ways of producing hydrogen gas, while also discussing the potential significance of interconnected systems such as this. The result indicated that the economic viability in constructing an interconnected system such as the one included in the study is substantially dependent on the variability of the price for electricity. It is also concluded that out of the modelled scenarios, two could be considered to have the possibility to become economically viable. One case consisted of an electrolyser being fed electric power directly from the wind farm, where the system was constantly available to act as a support system to the power grid. The other scenario considered viable based on the results was when the electrolyser was fed with electric power from the grid and set to be available to run while the spot price was below a threshold value. While the parameters used for sizing the system in the model cannot be considered to be optimized in all cases, the size of the electrolyser did not significantly affect the result of the simulated scenarios.
