According to the "12th Five-Year Plan" energy plan and renewable energy plan currently being formulated, it is expected that by 2015, China's offshore wind power capacity will reach 5 million kilowatts, and by 2020 it will reach 30 million kilowatts. At the same time, the National Energy Administration will start the bidding preparation for the second batch of offshore wind power concession projects in the second half of this year. It is expected that the bidding will be completed in the first half of next year and the total construction scale will be between 1.5 million and 2 million kilowatts.
In this regard, industry insiders unanimously believe that offshore wind power is at the forefront of global wind power technology development and industrial competition. China’s relevant departments and relevant parties must accelerate the research and industrialization of offshore wind power technology from the perspective of national strategies, and establish advanced technologies and supporting facilities. Complete offshore wind industry system to achieve large-scale development of offshore wind power.
The potential of offshore wind power "Wind power has unparalleled advantages of other energy sources." Shi Pengfei, vice chairman of the Wind Energy Special Committee of the Chinese Renewable Energy Society, told China United Business Daily that wind power has more potential for development than hydropower, which is more than nuclear power construction cycle. Short, safe, and more energy-efficient than traditional solar energy. Compared with onshore wind power, offshore wind power is close to the traditional power load center, which facilitates power grid consumption and eliminates the trouble of long-distance power transmission.
It is understood that China has relatively rich offshore wind resources. According to the results of the China Meteorological Administration's detailed investigation, the installed capacity of wind power at a depth of 50 meters in China’s seas with water depths of 5 to 25 meters is about 200 million kilowatts, and the installed capacity of wind power at depths of 5 to 50 meters and 70 meters is about 500 million kilowatts.
“China is the most promising country for developing offshore wind power. It is estimated that by 2020, China's offshore wind power market capacity will be basically equal to that of EU countries.†Gemey Global Offshore Wind Power Operation Officer Javier Perea stated that China’s 12th Five-Year Plan emphasizes The quality of development of wind power, rather than the pursuit of speed, Gemeji will consistently support the Chinese government's wind power development policy, to help China's wind power development in a healthy and sustainable manner.
In fact, not just Javier Perea, many people in the industry regard China as the only offshore wind power market outside of Europe that will develop rapidly by 2020.
According to the plan of the Chinese government, it is expected that by the end of 2015, China's offshore wind power capacity will reach 5 million kilowatts, and by the end of 2020 it will reach 30 million kilowatts. In the next five years, China's offshore wind power industry will focus on the development of Jiangsu and Shandong wind power bases.
During this period, offshore wind power construction in Hebei, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi, and Hainan will also be promoted. According to preliminary objectives, offshore wind power in Shanghai, Jiangsu, Zhejiang, Shandong, and Fujian provinces will have an installed capacity of about 10.1 million kilowatts in 2015, of which offshore wind power is 5.9 million kilowatts, and intertidal wind power is 4.2 million kilowatts; other provinces are set to target 5 million and 10 million kilowatts.
The wind turbine manufacturing industry will benefit The industry has once calculated an account: If calculated on a stand-alone capacity of 5 MW, China will need at least 6,000 wind turbines by 2020. Therefore, the implementation plan for offshore wind power has attracted many wind turbine manufacturing companies for R&D and investment.
Recently, Guodian United Power Technology Co., Ltd. announced that the 6 MW wind turbines positioned at sea will go offline within the year. Next year, the company will begin to develop 12 MW wind turbines; Shanghai Electric announced that it will release 5 MW offshore permanent-magnet direct-drive wind turbines at the end of this year or early next year; Goldwind said its first 6 MW direct drive wind turbine Magnetic offshore wind turbine prototypes will be rolled out at the end of this year or early next year, and will be mass-produced in 2014; China Shipbuilding Industry (Chongqing) Haifeng Wind Power Equipment Co., Ltd. announced that it will release a 5 MW turbine in October this year.
In October last year, 5 MW wind turbines independently developed and manufactured by Sinovel Wind Power went offline. In May of this year, the 6 MW wind turbine unit independently developed by the company will be officially produced. In August, the 5 MW wind turbine will be installed on site at the Donghai Bridge, and Huarui's 10 megawatt and above ultra-large wind turbines are also under development. Xiangdian Wind Power Co., Ltd. also launched a 5 MW permanent-magnet direct-drive offshore wind turbine in October last year. By the end of June this year, Xiangdian Wind Power will build offshore demonstration wind farms in the Netherlands and Fujian, China, respectively. It is expected that the power generation will be realized in the second half of this year. .
In fact, it is not only these wind turbine manufacturers that benefit, but also the upstream industrial chain that provides technical support for the manufacture of these wind turbines. Dow Chemical's AIRSTONE system combination for wind energy is a good example.
“The production of larger wind blades requires high-tech support. As a result, wind turbine manufacturers have adopted the Dow AIRSTONE wind energy system to create stronger, lighter, and easier-to-produce wind turbine blades.†Dow Chemical Company stakeholders According to China Union Business Daily.
It is understood that compared with polyester matrix composites, epoxy resin system materials represented by “AIRSTONE WIND ENERGY SYSTEM†have superior performance and can achieve the same strength with lighter weight, thus becoming the first choice for fan blades. material. Larger fan blades place higher demands on materials and processing; for this reason, Dow has introduced advanced impregnation systems based on epoxy resins and hardeners to help manufacturers meet various needs.
Although the prospects for the development of offshore wind power are very attractive, many people in the industry have stated to “China’s Joint Business Daily†that the development of offshore wind power is faced with great technical challenges in terms of the wind turbine itself, construction, transportation and installation. If the availability of equipment cannot be guaranteed, the development of offshore wind power will be difficult.
According to Javier Perea, Gomez Global Offshore Wind Power Operations Officer, the offshore operating environment is very harsh and offshore wind turbines are much more difficult to manufacture than onshore wind turbines. Once the wind turbines have problems, the cost of maintenance will be very high.
