Geographic islands share common issues regarding space limitation on land to install renewable energy plants, isolated power grids and few natural resources. This result in a high dependency on imported oil, with high costs for the population and the environment. As the costs of wind and solar energy fall, many governments have set targets to increase renewable energy production from the ocean (wave and tidal), trying also to alleviate the challenges of solar and wind intermittence through the introduction of wave and tidal technology, these resources are more predictable in terms of potential energy to be generated. Ocean energy can play an important role when it comes to accessing green hydrogen production or drinking water through desalination. This project arises in this context in order to investigate viable business models involving synergies between related markets by coupling photovoltaic energy, green hydrogen and offshore energy to reduce energy dependence and energy costs, as well as increase the efficiency of the electricity grid.
