The era of "wind power+" has come!
According to the report of the 20th National Congress of the Communist Party of China, China will actively and steadily promote carbon peaking and carbon neutralization. Based on China's energy and resource endowment, China will adhere to the principle of "standing first and breaking down later", and implement the carbon peaking action in a planned and step-by-step manner. As an important part of China's new energy industry, the development prospect of wind power industry is particularly broad.
Comprehensive energy integration development, such as wind power+pasture, wind power+hydrogen energy, wind power+energy storage, integration of wind, water, fire and storage, wind power+rural revitalization, is also promoting low-carbon and green development of regional energy. Now please follow me to explore.
Offshore wind power+marine ranch Recently, the construction of the 220 kV land booster station of Yantai Laizhou City offshore wind power and marine ranch integrated development research pilot project has been completed, and the project has entered the peak period of electrical equipment commissioning; Electric Wind Power won the bid for the world's first floating offshore wind power and fishery aquaculture integration equipment research and demonstration project, and will provide host equipment and towers for this project; The Longyuan Fujian Floating Fan Foundation Project jointly undertaken by Jinhai Intelligent Manufacturing and Zhongdao Construction, a factory based partner, was started. The project has three functions of integrated development of "wind power+pasture+photovoltaic"
Different from pure offshore wind power, the integrated development of "offshore wind power+marine ranching" is a typical representative of the highly efficient combination of modern agriculture and new energy industry, and an important new industrial model and future development direction of saving and intensive sea use. Offshore wind power+diversified development is becoming an emerging industry. In the past two years, offshore wind power+marine ranching can be said to have entered a substantial stage of promotion.
On November 11, Tian Qingjun, Senior Vice President of Vision Energy, pointed out at the 7th Global Offshore Wind Power Conference held in Haikou that "offshore wind power+" should be rationally distributed and the problem of power limitation and power abandonment should be solved in advance. He said that Hainan, Guangxi, Guangdong, Fujian, Jiangsu, Zhejiang and other coastal provinces will move towards offshore wind power development 2.0 and develop the "offshore wind power+" model according to local conditions.
Moreover, in the "Fourteenth Five Year Plan" energy planning issued by Guangxi, Shandong and other places, it is clearly encouraged to integrate offshore wind power with marine ranching. At the end of last year, Shandong Province also released the Notice on the "Fourteenth Five Year" Marine Economic Development Plan, which mentioned that it would actively explore and promote new technologies and new models such as "offshore wind power+marine ranching", the comprehensive utilization of offshore wind power and marine energy, and support the integrated development of marine clean energy and desalination, far-reaching marine aquaculture, marine observation, etc.
The Fourteenth Five Year Plan for Renewable Energy Development in Zhejiang Province points out that it will "explore a new development model of offshore wind power base" and intensively build a demonstration project of offshore wind power+marine energy+energy storage+hydrogen production+marine ranching+onshore industrial base.
The Fourteenth Five Year Plan for Marine Economic Development of Guangdong Province proposes to support the comprehensive development and utilization of marine resources, promote the combination of offshore wind power project development with marine ranching, offshore hydrogen production, sightseeing tourism, and marine comprehensive testing ground, and strive to achieve an installed capacity of 18 million kilowatts by the end of 2025..
It is understood that the tower foundation structure of offshore wind power can play a role similar to that of artificial reefs in gathering and breeding fish, providing a good habitat and spawning place for marine organisms such as fish, shellfish and algae. Therefore, the tower foundation of wind power can be fully used to develop deep-water aquaculture cages. After the offshore wind power is put into operation, it can not only produce green power, but also make rational use of the marine water space occupied by the wind farm to maximize the value of marine resources, which is in line with the trend of marine economic development.
To promote the further development of "offshore wind power+marine ranching", Yangjiang Municipal Bureau of Agriculture and Rural Affairs signed a framework cooperation agreement with a number of enterprises and scientific research institutions at the end of July this year to jointly promote the integrated development of "offshore wind power+marine ranching". On October 31, the first offshore wind power and marine ranching integration test demonstration project in Shandong Province completed the hoisting of all wind turbines. During the construction period of the project, aquaculture areas were arranged within 50 meters of the sea area around the wind turbine foundation, and spawning reefs, fish collecting reefs, and marine rare reefs were placed, providing an excellent habitat and spawning place for marine organisms such as fish, shellfish, and algae, and promoting the "three-dimensional development and utilization of water and underwater", Building a new model of "green energy+blue granary" and helping to build a replicable demonstration project of "offshore wind power+marine ranch" is a new way to enable the organic integration of modern energy system, marine ecological protection and economic and social development.
Wind power+hydrogen energy In recent years, although China's installed wind power has ranked first in the world, problems such as abandoning wind power and limiting power have also occurred. In order to solve this problem, the wind power market actively explores energy conversion methods and converts wind energy into hydrogen energy for use, which has become the focus of current research. Wind power hydrogen production is to directly pass the electricity generated by wind power through water electrolysis hydrogen production equipment to convert electric energy into hydrogen for long-term storage. At present, hydrogen generation from wind power in China has not only effectively solved the problem of large-scale wind abandonment, but also has great significance for the wind power absorption capacity of the integrated energy system. At the same time, it will also explore a new way of local renewable energy consumption different from energy storage, cooling and heating. In addition, hydrogen generation from wind power is expected to accelerate the further cost reduction of offshore wind power and enter the era of affordable Internet access.
At the time of the 2022 Beijing Winter Olympic Games and the Winter Paralympic Games this year, the Hebei Construction and Investment Wind Power Hydrogen Production Project in Chongli District, Zhangjiakou City came into the public's view.
The International Energy Network/Wind Power Headlines (WeChat: wind-2005s) learned that the voltage of wind turbines and photovoltaic power generation is very unstable due to environmental, weather and other factors. As the world's first off grid wind wind coupling renewable energy hydrogen production project through DC microgrid transmission, hydrogen can be produced without external power supply, and renewable energy power can also be delivered to the grid without hydrogen production. Wind power, hydropower, solar energy, etc. are called zero carbon energy. They are not only green and environmentally friendly, but also solve the problem that hydrogen production from electrolytic water is subject to high electricity prices and production costs.
It is reported that the hydrogen production capacity of Hebei Jiantou wind power hydrogen production project will reach more than 600 tons after its full capacity, laying a solid foundation for enterprises to integrate into Zhangjiakou hydrogen energy industry chain faster and stronger. At the same time, Zhangjiakou City strives to reduce the cost of hydrogen production from electrolytic water with renewable energy from 30 yuan to 14 yuan per kilogram. From this point of view, the wind power hydrogen production project has a good demonstration and driving significance, which also means that the "Fourteenth Five Year Plan" period will usher in the rapid development stage of the wind power hydrogen production industry.
In addition, with the continuous improvement of China's offshore wind power manufacturing, construction, operation and maintenance technology, it is possible to build a marine economic circle with offshore wind power as the core. "Offshore wind power+hydrogen production from seawater" is becoming the trend of comprehensive development of offshore energy, and building an offshore blue energy base is becoming a reality.
On June 20 this year, the Medium and Long term Plan for the Development of Shanghai's Hydrogen Energy Industry (2022-2035), issued by Shanghai, proposed that "in terms of offshore wind power hydrogen production, we should carry out research on technologies related to far-reaching offshore wind power hydrogen production, and actively carry out demonstration project construction in combination with the overall layout of Shanghai's far-reaching offshore wind power. We should break through the bottleneck of offshore hydrogen production using fresh water electrolysis, and reduce the cost of seawater hydrogen production."
The relevant planning of Zhangzhou, Fujian Province also proposes to accelerate the development of ten million kilowatts offshore wind power in the offshore shoals of Zhangzhou, lay out hydrogen energy industrial bases such as offshore wind power hydrogen production, develop hydrogen fuel waterborne intelligent transportation equipment, and build an industrial chain of "hydrogen production - hydrogenation - hydrogen storage".
On October 10, Tangshan Municipal People's Government issued Tangshan Offshore Wind Power Development Plan (2022-2035), in which hydrogen energy pointed out that: explore and cultivate a new mode of integrated development and application of "offshore wind power+hydrogen energy storage", and form a demonstration in wind power consumption, grid peak shaving and other aspects. Encourage the integration of "offshore wind power+hydrogen ammonia". Give full play to the advantages of long hydrogen energy regulation cycle and large energy storage capacity, carry out demonstration of hydrogen energy storage in offshore wind power consumption, grid peak shaving and other application scenarios, and cultivate and develop a new integrated application model of "offshore wind power+hydrogen energy storage". Actively promote the layout of offshore wind power+seawater desalination and hydrogen production from electrolytic water, and develop an integrated demonstration project of off grid offshore wind power and hydrogen production.
It can be predicted that in the future, offshore wind power will form a new industrial chain, especially offshore wind power hydrogen production, which is expected to become the key to breaking the situation of offshore wind power deep offshore development.
Wind power+energy storage
Wind power+energy storage wind power is a green and clean renewable energy, but due to its intermittent and volatile characteristics, large-scale grid connection will impact the stable operation of the power system.
At present, China's power grid requires electricity to be generated and used immediately. It is transmitted to users through the power grid, and electrical appliances are used directly. It goes through three major links: source network load. There is no storage environment in the middle. In addition, the scale of wind power installation increment in China is huge, but the consumption problem is still the pain point of the entire industry. Therefore, for the entire wind power industry, energy storage is of great significance to wind power.
At present, many provinces have issued policies and requirements related to new energy allocation and energy storage. In the construction plan of the international energy network/wind power headlines recently, 9 provinces and cities explicitly require wind power supporting energy storage. (Click for details: 204.49GW! 15 provinces and cities have clear scenery construction indicators)
It can be seen that "wind power project supporting energy storage" has become the standard configuration.
Without exception, in October this year, the Shanghai Development and Reform Commission issued the Work Plan for Competitive Configuration of Hangzhou Bay Offshore Wind Power Projects, which clearly required supporting construction of electrochemical and other energy storage devices, and reserved the proportion of energy storage configuration for more than 4 hours. It is required that the energy storage device should adapt to the offshore wind power application scenario, and have the functions of grid peak shaving, auxiliary frequency modulation, standby power supply, peak shaving and valley filling, power demand response, emergency power support, reactive power compensation, etc. Energy storage design, construction, operation maintenance and decommissioning shall comply with national and industrial regulations and specifications, and safety management shall meet the technical and management requirements of emergency management, fire protection, power supervision and other relevant departments.
Integration of scenery, water and fire storage In recent years, with the construction of a number of major projects, such as the demonstration project of the new generation green power station in Ulanchap, Inner Mongolia, the "integrated wind, water, fire and storage" comprehensive energy base in Chongzuo, Guangxi, the 8000 MW "integrated wind, water, fire and storage" project in Bazhou, Xinjiang, the "wind, water, fire and storage" multi energy complementary integration green power demonstration project in Yulin, as well as wind power generation above 1000 meters With the continuous breakthrough of major new energy technologies such as 300 MW compressed air energy storage power station, the pace of energy integration and development has become more firm and the path has become clearer.
New generation green power station demonstration project in Ulanchap, Inner Mongolia By giving priority to the use of clean energy such as wind power and photovoltaic, the "integration of wind, water, fire and storage" gives play to the regulation performance of hydropower and coal power, appropriately configures energy storage facilities, and coordinates the coordinated development and scientific allocation of multiple resources, which is conducive to giving play to the advantages of regions rich in new energy and realizing large-scale consumption of clean power. While optimizing the energy structure, it also breaks the resource and environmental constraints, which is of great significance for China to achieve the "dual carbon" goal and green development.
In recent two years, the national and local multi-dimensional layout and construction of the "scenery, water, fire and storage" multi energy complementary demonstration project have been carried out, and related projects have been successively implemented, especially the construction trend of large-scale scenery bases based on the multi energy complementary model has become clear. The insiders pointed out that in the future, "integration of wind, water, fire and storage" may become the mainstream model of the construction of the large wind base.
In terms of national and local policies, in March 2021, the National Development and Reform Commission and the National Energy Administration issued the Guiding Opinions on Promoting the Integration of Load and Storage of Electric Power Sources and Networks and the Complementary Development of Multi energy, which clearly put forward the "implementation path of multi energy complementation" and "promoting multi energy complementation to improve the consumption level of renewable energy".
In March this year, the National Development and Reform Commission and the National Energy Administration issued the "Fourteenth Five Year" Modern Energy System Plan, which further proposed that we should actively promote the construction of clean energy bases with multiple energy complementarities, scientifically optimize the scale and proportion of power sources, and give priority to the use of existing conventional power sources to implement multiple energy complementarities such as wind, water (storage) and wind, fire (storage) projects. In May, the National Energy Administration and the Ministry of Science and Technology issued the "Fourteenth Five Year Plan" for Scientific and Technological Innovation in the Energy Field, which took "the integration of source, grid, load and storage and the research on the planning and integrated design of the integration of wind, fire, water and storage" as an important research topic.
In the "Fourteenth Five Year Plan", Shaanxi, Ningxia and other places successively released the "scenery, water and fire storage" multi energy complementary demonstration project or base construction related planning, clearly accelerating the construction of "scenery, water and fire storage" multi energy complementary clean energy demonstration base. In this context, the construction focus of large scenic bases in western and northern provinces and regions, such as Inner Mongolia, Xinjiang, Qinghai, Gansu, also gradually tends to the multi energy complementary mode of "scenic water storage" and "scenic fire storage".
Not only that, in the Notice on the Application of Annual Construction Scale Projects of Wind Power PV Power Generation in 2023 issued by Guizhou Province in November this year, it was also clearly proposed that the development of wind power and photovoltaic power generation resources and the utilization of grid transmission channels should be coordinated according to the requirements of integration of wind, water, thermal storage, integration of source, grid, load and storage, and large-scale and base development.
With the support of relevant policies at the national and local levels, the "scenery, water and fire storage" multi energy complementary demonstration project has been favored by various energy enterprises. It has sprung up like bamboo shoots after a spring rain, and has been constructed in a multi-dimensional layout in various regions. (See details: 121.857GW "Scenery Storage" project in the first three quarters: China Energy Construction, Beijing Energy, Gansu and Inner Mongolia rank first)
Wind power+rural revitalization In recent years, China has adhered to the development concept of "green water and green mountains are golden mountains and silver mountains", made full use of abundant wind and solar energy resources, developed green economic industries such as field wind energy and photovoltaic power generation, helped rural revitalization, and achieved ecological protection and sustainable development.
At the beginning of this year, the National Energy Administration, the Ministry of Agriculture and Rural Development and the National Bureau of Rural Revitalization issued the Implementation Opinions on Accelerating the Transformation and Development of Rural Energy to Boost Rural Revitalization, which proposed that by 2025, a number of green and low-carbon rural energy pilot projects should be built, and the proportion of wind power, solar energy, biomass energy, geothermal energy, etc. in rural energy should continue to increase. Farmers' idle land and rural house roofs should be used to build distributed wind power and photovoltaic power generation, Allocate a certain proportion of energy storage, self use, local consumption, surplus electricity online, and farmers can obtain stable rent or electricity revenue.
Then, in June, Jilin Province issued the first provincial plan of "wind power+rural revitalization", which is the first demonstration of the national "wind control plan for thousands of villages and thousands of townships". Document requirements: In 2022, about 3000 administrative villages in 9 cities (prefectures) of Jilin Province, Changbai Mountain Management Committee and Meihekou City will carry out the new energy rural revitalization project (9034 administrative villages in the province have not carried out the rural revitalization project, and the number of administrative villages in each county (city, district) is subject to the data provided by the Provincial Department of Civil Affairs). Each administrative village will build a 100 kilowatt wind power project or a 200 kilowatt photovoltaic power generation project, which will be fully covered in the province in 2024.
On August 12, at the decentralized wind power technology seminar, Wang Dapeng, Deputy Director of the Department of New and Renewable Energy of the National Energy Administration, said that the next step would be to innovate the wind power investment and construction mode and land use mechanism, focus on the implementation of the "wind action in thousands of villages", vigorously promote the development of rural wind power, and encourage village collectives to participate in the development of decentralized wind power projects through mechanisms such as pricing and equity, revenue sharing, etc. At present, we are organizing the preparation of the "Wind Control Action for Thousands of Villages and Towns" plan to promote its implementation as soon as possible..
Qin Haiyan, Vice Chairman of the World Wind Energy Association and Secretary General of the Wind Energy Professional Committee of the China Renewable Energy Society, pointed out in a reporter interview that "the 'Wind Control Action for Thousands of Villages and Towns' is a combination of the national rural revitalization strategy to explore a deep combination of low-carbon energy industry development and promoting common prosperity. It is both long-term and pragmatic, fully reflecting a comprehensive and systematic planning thinking and a pioneering and innovative policy vision."
Up to now, the pilot project of "Wind Control Action in Thousands of Villages" has been started in Huaibin County, Henan Province on September 29. It is reported that this is the first batch of pilot projects that the country took the lead in preparing the implementation plan and starting construction of the "Wind Control Action in Thousands of Villages and Towns".
The total investment of the pilot project of "Wind Control Action in Thousands of Villages and Towns" in Huaibin County, Henan Province is 15 billion yuan. It is planned to select 295 stands in 295 administrative villages of 19 townships and towns in the county, with a total installed capacity of about 1800 MW. It is planned to realize the first batch of 650 MW projects to be connected to the grid for power generation by the end of 2023, and 1150 MW will remain to be connected to the grid for power generation by the end of 2024. |
