Abstract: In recent years, under the goal of “carbon peak and carbon neutrality”, the field of renewable energy has made great progress. Offshore wind power technology is expected to become the mainstay of green energy sources in the future due to its advantages of abundant resources and large utilization prospects. But at present, offshore wind farms, especially far-reaching offshore wind farms, are still faced with problems such as difficulty in construction and immaturity of wind power consumption technology. This paper first introduces the current development status of offshore wind power, analyzes the advantages and disadvantages of current offshore wind power transmission technology, introduces the current new technologies in the field of offshore wind power, analyzes and summarizes the offshore wind power hydrogen production technology and hydrogen transfer technology. Combined with the development trend, this paper summarizes the development of offshore wind power in the future, which should be divided into two main lines: offshore wind power and far-reaching offshore wind power, puts forward the view that the development of offshore wind power and hydrogen energy should be closely combined, introduces the idea of combining offshore wind power with hydrogen storage and energy storage, and forecasts the prospect of offshore wind power and far-reaching offshore wind power respectively, which can provide ideas for solving the problems faced by offshore wind power sites. It can also provide reference for the further development of offshore wind power.
