Abstract
Offshore energy islands,as innovative carriers for the development and utilization of marine renewable energy,are reshaping the global energy landscape through multi-energy complementarity,system integration,and efficient use of resources.This article systematically analyzes the development trends of energy islands and the necessity of constructing offshore energy islands in China from various dimensions,including concept definition,importance,feasibility,foreign cases,considerations,and construction plans.Using islands(natural or artificial)as offshore green energy islands(green energy distribution center)can effectively enhance the storage and transmission solutions for offshore wind energy,increasing overall efficiency by up to 25％and achieving stable power output.With the reduction in production costs,offshore wind energy for green hydrogen production will become one of the main sources of hydrogen energy,with offshore energy islands serving as production and storage bases for green hydrogen.The integration of energy forms like photovoltaic,tidal,and wave energy provides assurance for achieving multi-energy complementary in energy islands.Energy islands and surrounding offshore wind platforms can be equipped with various observation instruments to provide continuous online monitoring services,offering a valuable information platform for marine disaster prevention and reduction.The construction of new offshore green energy islands under high-quality development will contribute to China's dual carbon goals.关键词
