| Abstract: | The North Sea has a large potential for offshore wind power. One way to connect offshore wind farms to shore is via offshore energy hubs. At an energy hub, energy can be collected, distributed, converted and/or stored. In this thesis, an optimisation study has been performed on the system role of energy hubs in the North Sea. The energy system of the North Sea region has been modelled using the modelling framework PyPSA. The offshore nodes in the model configuration can be connected to each other and to shore via AC connections, DC connections and/or hydrogen pipelines. A scenario study was performed to test the model extensions and different model configurations. AC connections hardly play a role in the optimised energy system of the future in the North Sea. A synergy was found between electrical DC connections and offshore hydrogen conversion and distribution. With the implementation of the model extensions the total annual energy system cost of the North Sea countries has been reduced with 967 M€. Moreover, the introduction of offshore electrolysis reduces the installed electrical transmission capacity in the North Sea by 23%. |
