How to resolve the offshore wind cost crisis?

Offshore wind energy is an inexhaustible treasure trove, but compared with onshore wind power, the high cost is a difficult
problem to develop offshore wind power.
Comparing the project cost composition of the two, it can be found that wind turbines account for 60%-80% of the cost of onshore wind power, while wind turbines account for less than half of the cost of offshore wind power, of which other costs such as research and development, approval, licensing, and consulting account for about
30%.

According to relevant data, offshore wind power has a high wind speed and generates 50% more power than onshore wind power, although this can partially offset its higher investment costs, but in order to pursue better wind resources, offshore wind farms are located farther and farther offshore, and the water is getting deeper and deeper, which has brought a series of costs such as foundation, grid connection and installation

On April 22, the "Fifth Annual Conference of the National Offshore Wind Power Engineering Technology Research Center Committee and International Offshore Wind Power High-level Technology Forum" was held in Beijing, Qin Haiyan, Secretary-General of the Wind Energy Professional Committee of the China Renewable Energy Society, Yang Benxin, General Manager of Chongqing Shipbuilding Industry Company, Yao Xingjia, Director of the Wind Energy Professional Committee of Shenyang University of Technology, and Yao Xingjia, Director of the Wind Energy Professional Committee of China Renewable Energy Society, and many other industry celebrities delivered relevant keynote speeches
。 Qin Haiyan pointed out that offshore wind power represents the frontier and commanding heights in the field of wind power technology, and strengthening technological innovation is an important driving force for reducing the cost of
wind power generation.
For example, the design and application of large units with higher reliability and output, more reasonable wind farm layout design and the development of intelligent control technology all provide realistic possibilities
for offshore wind power cost reduction.
At the same time, the formation of a mature supply chain in the industry, the cooperation between upstream and downstream of the industry, and the innovative investment and financing methods in the field of renewable energy are also necessary
to solve the cost problem.

Yang Benxin believes that the current on-grid electricity price of offshore wind power is low, and the risk and high cost of offshore wind power projects are high, and it is precisely because of the uncertainty brought by these risks and costs that developers have pressed the purchase price of wind power equipment very low, which in turn puts pressure
on wind power equipment manufacturers.
From the experience of this industrial development in Europe and the United States, the government should have the responsibility to help the maturity of the market, should concentrate funds, support several manufacturers with high technological maturity in the industry, carry out centralized demonstration, and cultivate and improve the industrial market
as soon as possible.

At present, most of the offshore wind power field still relies on the investment of the enterprise field, and the investment of hundreds of millions of dollars often overwhelms enterprises, Yao Xingjia suggested that the government should support more from the policy support, on the other hand, in order to avoid irreversible results, do a good job in technology, market, operation and maintenance and other aspects of preparation, to seek speed in stability, can not just pursue speed
