Nowadays the call for more sustainable solutions is ever growing. With an uncertain future it hasnever been more important for innovations and changes to the world’s energy generation. Each country must do its part. In Europe the potential for offshore wind power in the Baltic Sea is substantial. Hydrogen can be key in the energy system transition. An investigation into the role of offshore wind to produce green hydrogen in a future integrated energy system was performed including its interaction with other system elements. The paper is based on research-based data implemented in the energy system modelling tool Balmorel. By performing energy system optimization in a model application of the European energy system and the Baltic Sea connected grid towards 2050. It is found that given the right political framework conditions we find that offshore wind could play a significant role in the future, and that offshore wind energy could form the necessary conditions to produce green hydrogen. Demand and costs were given the upmost priority for this synergy to be favored over other energy sources.
