Research on the Offshore Renewable Energy Island System

In the case of shortage of fossil energy, the energy island integrating renewable energy such as photovoltaic and wind energy has attracted wide attention from all countries in the world. The energy island is a comprehensive energy utilization system, which can realize the collection and utilization of natural energy. It mainly includes energy utilization (power generation system), energy consumption (power consumption system) and energy balance (energy storage and micro-grid system). Building an energy island into an energy storage, conversion and transportation center can reduce the cost of land and sea energy transmission. In addition to transmitting energy to the land in the form of traditional electricity, the energy island can also be used as a base to build factories for centralized preparation, transportation and storage of hydrogen. The establishment of the energy island is conducive to further development of marine resources and marine experiments. Combine offshore ranching in the high seas with offshore wind power, take energy supply as the main body, and fishery and tourism as the auxiliary, to explore more potential value of the energy island. The offshore renewable energy island can improve the overall economic benefits, and make contributions to ensuring energy security and promoting the energy revolution.
