电-氢-氨协同的海上能源岛:研究进展、技术展望及工程设想OA

As a hub for offshore energy supply and conversion,the energy island can not only mitigate the fluctuation of renewable energy output but also achieve cross-temporal and spatial storage and clean utilization of energy.This paper introduces the basic concept of the energy island and its core features of multi-energy complementarity,spatial intensification and intelligent management.It also analyzes the policy support and research progress.In response to the complexity of the marine environment and the challenges of multi-energy system coupling,key technologies such as energy master planning,flexible electrical interconnection control,bidirectional efficient and flexible conversion of electricity-hydrogen-ammonia,energy management,and platform safety design need to be broken through in the future.This paper also discusses the demonstration project conception of"electricity-hydrogen-ammonia"synergy and engineering implementation risks.The research can provide innovative idea for the efficient utilization of renewable energy in the deep sea and is of great significance for achieving the goals of carbon emission peak and carbon neutrality.
