Insight into China’s offshore wind power industry in 2022 From 36 krypton Research Institute

The following is the Insight into China’s offshore wind power industry in 2022 From 36 krypton Research Institute recommended by recordtrend.com. And this article belongs to the classification: new energy.

Offshore wind power is an important development direction of the new generation of wind power. Compared with traditional power generation methods, offshore wind power has the advantages of clean and low carbon, high power generation efficiency, no occupation of land resources, suitable for large-scale development, convenient water transportation of wind turbines, proximity to coastal power load centers, etc. The development of offshore wind power is of great significance for achieving the goals of “carbon peaking” and “carbon neutralization”, promoting the transformation of China’s energy structure and cultivating new drivers of green economic development.

China is rich in offshore wind energy resources. In recent years, the scale of offshore wind power development has been expanding. According to the data of the national energy administration, China’s offshore wind power installed capacity increased from 0.59gw in 2016 to 16.9gw in 2021, with an average annual compound growth rate of 95.6%; The cumulative installed capacity increased from 1.63gw in 2016 to 26.39gw in 2021, with an average annual compound growth rate of 74.5%. China has become the country with the largest cumulative installed capacity of offshore wind power in the world.

Policy driven

The implementation of a number of top-level plans and supporting policies has pointed out the development direction for the development of the wind power industry. In January, 2020, the Ministry of finance, the national development and Reform Commission and the Energy Administration issued several opinions on promoting the healthy development of non-aqueous renewable energy power generation (CJ [2020] No. 4), stipulating that new offshore wind power projects from 2020 will no longer enjoy the central financial subsidy, while inventory projects will not enjoy the central financial subsidy until all units are connected to the grid before December 31, 2021, which will lead to the tide of offshore wind power installation in 2021, In 2021, the newly added installed capacity increased by 452% year-on-year. In January, 2022, the national development and Reform Commission and the National Energy Administration issued the “14th five year plan” for modern energy system, proposing to promote the layout of offshore wind power in deep water and far shore areas, promote the R & D and demonstration application of offshore wind power development technology in far-reaching sea areas, and focus on the construction of offshore wind power bases in Guangdong, Fujian, Zhejiang, Jiangsu, Shandong, etc. The release of a series of policies has helped China’s offshore wind power industry move towards a period of low-cost, large-scale and affordable development.

Industrial chain structure

The offshore wind power industry chain consists of three parts: upstream parts suppliers, midstream machine assembly enterprises, and downstream operation and maintenance parties.

(1) Upstream: offshore wind power related parts include hub, blade, generator, gearbox, bearing, casting, tower, etc. 1) Blade. The blade of wind turbine is one of the key core components of wind turbine. The design, manufacture and operation status of the blade directly affect the performance and power generation efficiency of the whole machine, and have a significant impact on the operation cost of the wind farm. 2) Gearbox. According to the working principle of wind power generation, the larger the wind turbine radius, the greater the power of a single machine, the lower the power generation cost, and the large-scale wind turbine is the trend; The gearbox of wind turbine generator is located in the engine room. It is a weak link in the transmission chain of MW wind turbine. It is a component prone to overload and high damage rate. The reliability of offshore high-power wind turbine gearbox plays a decisive role in the service life of the wind turbine. 3) Bearings. At present, the high-end bearings supporting high-power models in China mainly rely on imports, and the premium of high-end bearings is obvious. 4) Castings. China is the main producer of castings. However, due to the stricter environmental protection policies and the long production expansion cycle of castings, the growth rate of domestic casting capacity in the past two years is low.

In terms of the cost distribution of wind farms, according to the data of Ping An Securities, wind turbines including parts and components will be the largest part of China’s offshore wind power costs in 2021, accounting for 48%. In terms of the degree of localization, except for the main shaft bearings, other links have basically achieved localization, and some high-quality enterprises in the casting and forging links such as main shafts and hubs have achieved export.

(2) Midstream: the overall assembly industry of offshore wind turbine is highly concentrated. The top four manufacturers with the highest market share of offshore wind turbines in the global market are Siemens COMESA, Mitsubishi Vestas, Shanghai Electric and Goldwind technology. In terms of domestic offshore wind turbine manufacturers, Shanghai Electric, vision energy, Goldwind technology and Mingyang intelligent occupy a large share in the new installed capacity.

(3) Downstream: the downstream of the offshore wind power industry chain includes offshore wind power operation and equipment maintenance. Compared with onshore wind power, offshore wind power has higher technical barriers, large initial investment, long project cycle, and more complex development process, which requires the coordination and approval of relevant departments. Therefore, it has higher requirements on the wind power development experience of developers. Offshore wind power operators and operators are mainly large central enterprises, such as Guodian power, Three Gorges new energy, state power investment, Datang new energy, China Guangdong nuclear power, etc. In terms of regional distribution, Zhejiang, Jiangsu, Guangdong, Shanghai and other regions are rich in wind energy resources, which has become a hot distribution area for offshore wind power. At present, the distribution density in the south is greater than that in the north.

Industry development trend

(1) Market growth trend: China’s offshore wind power will maintain a stable growth trend in the future

With the official withdrawal of state subsidies in 2022, the growth of China’s offshore wind power market is expected to slow down significantly. The future growth will mainly depend on local support and the industry’s competitiveness in the power market. According to GWEC (Global Wind Energy Association), China’s offshore wind power will maintain a stable growth trend in the future. It is estimated that the cumulative installed capacity of China’s offshore wind power will reach about 60GW by 2030.

(2) Technology development trend: many technologies such as unit design and offshore power transmission need to be broken through to help the offshore wind power industry reduce costs and increase efficiency

Offshore wind power technology includes wind turbine unit, offshore power transmission, offshore engineering and operation and maintenance technology. Due to the limited development experience and technical maturity, the development of offshore wind power often faces high investment and high risk, and the cost problem is still the primary problem restricting the development of offshore wind power.

In the future, the offshore wind power industry will continue to focus on the above four types of technologies and drive the whole industry to achieve cost reduction and efficiency increase through technological breakthrough and innovation. Among them, through the design of new and special wind turbines and the improvement of offshore related construction technology, the utilization efficiency of wind energy can be improved and the installation cost can be reduced; Through the breakthrough of power prediction technology, fan intelligent torque and blade control and intelligent operation and maintenance, the reliability and power generation of the unit can be improved and the operation cost of the unit can be reduced; Through the overall design and construction optimization of the new large capacity floating offshore wind farm station, the offshore wind energy resources can be fully utilized to help the long-term offshore wind power parity on the Internet.
