Blue Energy Spearheading the Energy Transition: the Case of Crete

In the framework of the energy transition, in Europe now supported also by European green deal, energy systems are going to be transformed from fossil-fuel based, with the dispatchable generation, to variable renewable energy-based, with variable and non-dispatchable generation. This change is possible in case the abundant resource is available. Blue energy, and in particular offshore wind power, is yet to be employed in the amounts that could be relevant. In this research, offshore wind power is considered the main driver of the energy transition for the case of the island of Crete. The energy systems’ development scenarios are modeled using an energy planning software EnergyPLAN, starting from a reference model developed for the year 2017. The model was validated using the data provided by EUROSTAT and IEA. The large intake of variable energy from offshore wind was shown to provide more energy than it is possible to integrate into the local system using only storage and demand response. For this reason, additional scenarios were modeled to investigate the production of electrofuels from excess electricity. Such transformations enabled system-wide decarbonisation.
