Zhonglu Co., Ltd. joins hands with the central state-owned enterprise China Energy Construction to target high-altitude wind power industrialization strategic cooperation

2021-05-15 15:09

Shanghai Securities News China Securities Network News Zhonglu Co., Ltd. and China Energy Construction Co., Ltd. (hereinafter referred to as “China Energy Construction”) signed an agreement in Beijing on the 14th to carry out strategic cooperation on the industrialization of high-altitude wind power generation. This signing shows that Zhonglu has been committed to the development of high-altitude wind energy technology for many years and has won the support of my country’s leading central enterprises in the field of energy construction, which will help the company further adjust its industrial structure and extend its main business to new energy construction new tracks.

The cooperation agreement signed by the two parties focuses on the development of high-altitude wind power projects in all aspects, mainly including strengthening high-altitude wind power generation policy research and standard cooperation; relying on the company’s existing 2.5MW high-altitude wind power test power station in Wuhu, strengthening high-altitude wind power technology cooperation and solving technical obstacles , To create conditions for the construction and grid connection of high-altitude wind power demonstration projects; strengthen cooperation in the manufacture of high-altitude wind power generation equipment; strengthen cooperation in high-altitude wind power demonstration projects, take advantage of the integration of China’s energy construction, investment and construction, and cooperate to promote the company’s Jixi 100MW high-altitude wind power generation The station demonstration project was completed and landed.

It is understood that Song Hailiang, Secretary of the Party Committee and Chairman of Energy China, Wen Bin, Director of the Information Division of the High-tech Department of the Ministry of Science and Technology, and Wu Yun, Deputy General Manager of Energy China, went to Wuhu, Anhui on March 13 this year. Wuhu High-altitude Wind Energy Test Power Station, Umbrella Ladder Test R&D Center, and Production Test Base, and conducted in-depth exchanges with Zhonglu on the development and application of high-altitude wind energy power generation technology and mutually beneficial cooperation. Song Hailiang pointed out that it is necessary to conscientiously implement the “four revolutions, one cooperation” new energy security strategy proposed by the Party Central Committee and achieve the goal of “carbon peak and carbon neutrality”. Technical support and innovation leadership are indispensable. He expects that the high-altitude wind power generation technology of Zhonglu can go from scientific research and experiment to vector production and application, and then go to the center of the stage of new energy development.

Zhonglu has paid attention to new energy projects earlier. After investing and merging into Guangdong High-altitude Wind Energy Technology Co., Ltd. in 2014, it has been committed to in-depth technical research and development of 300-10,000-meter high-altitude wind power projects and power plant pilot trials, etc., and strive to improve the traditional The low-domain wind power generation has the disadvantages of high construction cost and low wind energy utilization rate. The high-altitude wind energy resources are efficiently converted to electric energy, and the power generation cost is also comparable to the on-grid power price of thermal power.

It is reported that the high-altitude wind energy power generation technology uses the industry’s unique parachute ladder structure to absorb high-altitude wind energy, drives the ground hoist and gear box to rotate through cables, and converts the wind energy into mechanical energy. Finally, the mechanical energy is converted into electrical energy through ground power generation equipment. Stable and continuous power generation is characterized by environmental protection, high wind energy utilization, and significant economic benefits. Compared with traditional wind power, the umbrella-ladder combined high-altitude wind power generation technology has many advantages such as environmental protection advantages, high stability, smart peak shaving and long-term continuous power generation.

According to Chen Shan, Chairman of Zhonglu Co., Ltd., Zhonglu High-altitude Wind Energy Jixi 100MW Power Station was officially approved by the Energy Bureau of the Anhui Provincial Development and Reform Commission in August 2017.

Original title: China’s first high-altitude wind power project has stalled due to funding issues

Reporter | Xi Jinghua

There is no need to build towers and blades, and the power generation device is floated into the air in a manner similar to flying a kite to generate power. This is China’s first high-altitude wind power project planned and constructed in Jixi, Anhui. However, due to funding problems, this project has stalled.

On February 18, ZhongluCo., Ltd. (hereinafter referred to as Zhonglu Co., Ltd., 600818.SH) issued an announcement stating that the Jixi High-altitude Wind Power Project could not be completed as scheduled due to the large funding gap of the project and the difficulty in financing.

The project is the first large-scale and commercial construction project of high-altitude wind power in China. The total construction scale is 100 MW. It is developed and constructed by Jixi Middle Road High-altitude Wind Power Co., Ltd., a subsidiary of Zhonglu Co., Ltd., with a total investment of 790 million yuan.

In August 2017, the Jixi High-altitude Wind Power Project was approved by the Anhui Provincial Development and Reform Commission and was implemented in phases.

Zhonglu shares plans to install two 5 MW high-altitude wind energy generating units developed by Guangdong Gaoaltitude Wind Energy Technology Co., Ltd. (hereinafter referred to as Guangdong Gaoaltitude Wind Energy) with an installed capacity of 10 MW in the first phase of the project.

In January 2018, the first phase of the project started in Jinsha Town, Jixi, Anhui. The construction of the main building project is planned to be completed by the end of November 2019. The project will be completed by the end of March 2020. The commissioning and grid-connected power generation will be completed in the first half of 2020, and the electricity will be merged into the State Grid. .

On April 16, 2019, Zhonglu adjusted the estimated budget for the first phase of the project from 93 million yuan to 175 million yuan. As of June 18 of that year, the project had invested a total of approximately 19.12 million yuan, accounting for 10.93% of the estimated budget for the first phase of the project.

Up to now, the project has only completed the structural topping of the pile foundation and electric control building of the first phase of the main plant.

The announcement stated that the high-altitude wind energy project is an internationally leading cutting-edge technology, and the project has a greater demand for follow-up funds. Since the project entered the design and construction, Zhonglu has been under greater financial pressure, and the project construction and commissioned processing equipment have come to a standstill.

As of the third quarter of 2019, Zhonglu’s book currency funds amounted to 28,165,800 yuan, a decrease of 83.69% from the beginning of the year. Due to bank loans, Zhonglu’s book short-term loan amount was 79 million yuan, a decrease of 41.48% from the beginning of the year.

Zhonglu said that in addition to financial pressure, the Jixi high-altitude wind energy project is also affected by factors such as the project’s ground mechanical system is a non-standard customized product, and the processing technology is special, and the supplier needs a long time to schedule special production and testing.

High-altitude wind energy is a kind of renewable clean energy with huge reserves and widespread distribution. Its theoretical power generation time exceeds 95%, and the annual power generation time can be as high as 6500 hours.

Compared with traditional wind power, high-altitude wind power is mostly based on kite flying and multi-kites in series, which captures better wind resources. The power generation cost is about 1/3 of traditional wind power, and it covers an area of only 1/30, and eliminates noise problems. The impact on the environment is small.

In 2013, there was an international upsurge of investment in high-altitude wind power, and technology research and development capabilities were basically based in North America, Europe, and Germany. However, large-scale commercial use has not yet been achieved.

In November 2009, Guangdong High-altitude Wind Energy settled in Guangzhou. According to the information from Tianyan Check, Guangdong High-altitude Wind Energy is the first domestic enterprise with mid-to-high-altitude wind power generation technology.

In December 2014, Zhonglu Co., Ltd. invested 40.491 million yuan in Guangdong Gaokong Wind Energy and increased its holdings. After the transaction is completed, Zhonglu shares hold 58.04% of the shares of Guangdong Gaokong Wind Energy.

On December 4 of that year, Zhonglu also issued a non-public share offering plan, which planned to raise 2.5 billion yuan to invest in the construction of a 400 MW high-altitude wind power project and to supplement working capital.

The plan announcement shows that the high-altitude wind power generation system developed by Zhonglu is an umbrella-ladder combination high-altitude wind power generation system, which is mainly composed of an air part, a ground part and system control. The air system is composed of one or several power parachutes and several balanced parachutes; the ground system It is mainly composed of generator, hoist (drum and reverse rotation motor) and universal pulley; the umbrellas, the working umbrella and the hoist are connected by light and high-strength cables.

In 2015, Guangdong High-altitude Wind Energy’s high-altitude wind energy demonstration power station project in Wuhu County, Anhui Province was operated. From May 4th to July 12th, 2015, it carried out nine flying power generation operations. The operating altitude is between 132 meters and 488 meters, and the cumulative power generation time of the equipment is 53 hours, with a total power generation of 31,000 kWh.

In 2016, the National Development and Reform Commission and the National Energy Administration issued the “Energy Technology Revolution and Innovation Action (2016-2030)”, which clearly carried out research on key technologies of large-scale high-altitude wind turbines. According to the plan, a complete set of wind power generation technologies at an altitude of 200 meters to 300 meters will be formed in 2020, and will be applied and promoted in 2030.

Zhonglu Co., Ltd. is the parent company of Forever Bicycle. According to the information from Tianyancha, Zhonglu Co., Ltd. was formerly known as Shanghai Bicycle Factory. It acquired permanent shares in July 2001. Its main business is the production and sales of bicycles, parts, mopeds and other special vehicles and other bicycle-related products.

The performance pre-loss announcement shows that in 2019, Zhonglu shares are expected to lose 60 million to 80 million yuan.

Zhonglu shares stated that the reason for the performance loss was the rapid changes in the shared bicycle market and the shrinking of the sports industry market, which resulted in the inability to collect the relevant accounts receivable in time and the inventory pressure, based on which accounts receivable and inventory impairment losses were calculated.

Guangdong High-altitude Wind Energy has also been at a loss. From 2016 to 2018, losses were 25.225 million yuan, 23.937 million yuan and 24.65 million yuan respectively.

Wind power generation at an altitude of 10,000 meters “blows into” China

Schematic diagram of kite-type high-altitude wind turbine simulation

my country is a country with large resources, but few people have noticed that my country is also a country with high-altitude wind energy.
Earlier this year, US media reported that scientists are trying to use high-altitude wind power to power New York City. Using this technology, scientists will collect wind energy from an altitude of 10,000 meters.
In fact, the high-altitude wind energy density in my country’s Jiangsu, Zhejiang and Shandong regions is much greater than that of New York, the highest in the world.
Wind power is the fastest growing energy industry in the world today, and it has grown at an annual rate of 30% for 10 years. However, the current use of wind energy is limited to low altitudes of tens of meters to 100 meters, and its major drawback is that it is not constant and reliable. At an altitude of several kilometers to 10,000 meters, not only the wind speed is greater, but also the wind is stable, and the period of the year without wind is less than 5%. Experts generally believe that high-altitude wind energy is hundreds of times higher than the ground.
Ken Caldera, a climate scientist at the Carnegie Institution of Stanford University, believes that the total energy contained in wind is 100 times the total energy required by people on Earth, but most of the wind energy is located high in the sky. Brian Roberts, a professor of mechanical engineering at the University of Technology Sydney, Australia, said that at altitudes of 4,600 meters to 10,000 meters, the airflow is strong and stable, making it an ideal aerial wind power plant.
Although it sounds beautiful, it is obviously impossible to make a turbine as high as 10,000 meters. At present, many developed countries are developing high-altitude wind power technology.
Recently, at the 2009 Clean Energy International Summit Forum in Dongying, Shandong, Dr. Zhang Jianjun, Chairman of California Tianfeng Co., Ltd., introduced his own research and development of high-altitude wind power technology, and revealed that China’s first high-altitude wind power demonstration project will be established in Guangdong Province.
High-altitude wind power around the world When the
energy crisis broke out in the 1970s, various high-altitude wind power designs continued to emerge. The U.S. Department of Energy once carried out a high-altitude wind power project, but in the 1980s, officials of the Department of Energy embezzled funds for other purposes, which eventually caused it to die. However, research on high-altitude wind power in developed countries has not stopped.
According to the reporter’s understanding, there are currently two main ways to structure high-altitude wind power. The first is to build a power station in the air, and then transport it to the ground through cables; the second is similar to flying a “kite”, which generates mechanical energy through stretching, which is then converted into electrical energy by a generator.
Dutch scientists put a typical kite into the sky. In 2008, according to the British “Guardian” report, scientists from the Delft University of Technology in the Netherlands put a kite with an area of 10 square meters into an altitude of 1,000 meters. The kite was finally produced by pulling the rope connected to the ground generator. 10 kilowatts of electricity. The researchers also designed a trapezoidal power station composed of numerous kites that can generate 100 megawatts of current.
Compared with the kite in the Netherlands, the installation in Italy is more like a “carousel” for flying kites. According to Italian media reports, in 2007, Italy launched the KiteGen plan for kite wind generators. The power generation principle of the device is that a 500-800-meter-high kite drives a turntable on the ground to rotate in a magnetic field to generate electricity under the action of wind. The researchers estimated through calculations that a turntable with a diameter of 1,600 meters and a kite with a diameter of 2,000 square meters can generate up to 1 million kilowatts, which is equivalent to 1/30 of the current electricity in Italy.
While Italy was actively building carousel kites, the United States also launched the “High-altitude Windmill” program. In this plan, generators and other major power generation equipment all follow the kite and fly into the air driven by wind turbines, and finally hover at an altitude of 10,000 meters. Here, the strong airflow of nearly 320 kilometers per hour blows the windmill blades to generate electricity, and then the electrical energy is transmitted to the ground at a high voltage of 20,000 volts by cables. Experts say that 300 of these power-generating kites are enough to supply the electricity needs of the entire city of Chicago.
In addition, there are many ideas about kite power generation around the world. Such as Canada’s “airship windmill”, Germany’s roof small household kite power station and so on.
According to calculations, the construction costs and power generation costs of these high-altitude wind power are far lower than fossil fuels and conventional low-altitude wind power. Almost everyone calls it “an energy revolution.”
However, the fact is that some foreign research has stopped due to lack of financial support. For example, although the “high-altitude windmill field” has been successfully tested in the ground wind tunnel, it is still coldly treated by investors. George Douglas, a spokesperson for the National Renewable Energy Laboratory, pointed out: “We are now largely focused on projects that can be commercialized quickly.”
At present, several companies in the United States and Italy are continuing the development of high-altitude wind motors, and they have taken the lead in the market. The American company Magenn expects to sell 2 to 4 working prototypes in 2010. Experts point out that the speed at which the technology enters the market depends on how much investment will be made. If funds are sufficient, the kite power station is likely to enter the commercial operation stage within 5 years.
High-altitude power generation landing in China The
east coast of North America and the coastal areas of China are excellent high-altitude wind resource areas.
According to the reporter’s understanding, the wind density of the most advanced ground-based wind power plants is less than 1 kW/m2. In the vicinity of the jet stream over New York, the wind density can reach 16 kW/m2; the average wind density in most areas at an altitude of 10,000 meters above China’s land is more than 5 kW/m2, while the wind density near the upper jet stream over the Jiangsu, Zhejiang and Lu area It can even reach 30 kilowatts/square meter, the highest in the world.
Zhang Xiuzhi, a researcher at the National Climate Center of the China Meteorological Administration, pointed out that Jiangsu, Zhejiang and Shandong are excellent areas for using high-altitude wind energy. Zhang Jianjun said that this is also one of the reasons why he returned to China to apply high-altitude wind power technology.
Zhang Jianjun was born in Meizhou City, Guangdong Province. He graduated from the Department of Electronics of Sun Yat-Sen University, and later obtained a doctorate degree in the United States. He served as the technical director of several companies in the United States and holds a number of invention patents. In 2005, he started his own business, founded Tianfeng Company in California, and invented a new type of high-altitude wind power technology called “Tianfeng Technology.” This is also a kind of “kite” high-altitude wind power technology.
According to his introduction to the “Science Times” reporter, the main principle of Tianfeng technology is to make the kite rise with the help of the wind like a glider, and the generated pulling force pulls the cable to drive the generator to generate electricity; when the kite rises to the maximum height, the control system adjusts the kite. The angle of the wings allows it to use its own gravity to descend. Then power up again, and so on.
Zhang Jianjun pointed out that this high-altitude wind power technology has two major technical difficulties, one is materials, and the other is control technology. First of all, in order to send the kite to the sky by the wind, the kite must be made of ultra-light materials, while having the characteristics of high strength and corrosion resistance. The material he finally chose was not developed until the last two years. Although the selected cable is lighter than water, it has high strength and is fully resistant to cutting.
Although the principle of high-altitude wind power is simple, the specific control technology is extremely complex and sophisticated. Through several years of research, Zhang Jianjun, who has a background in electronics, has made a breakthrough in control technology. In the end, the three sets of prototypes with different powers independently developed by Tianfeng in the United States can not only operate normally under typhoons and storms; through tests under various weather conditions, Zhang Jianjun also found that they are similar to existing high-altitude wind power technologies abroad. Compared with Tianfeng technology, it is more stable and can be operated at high and low altitudes.
Zhang Jianjun said that compared with traditional wind power, the investment cost of high-altitude wind power is about 1/3 to 1/2 of that of conventional wind power. Less affected. However, the high altitude within its range must be forbidden to fly.
At present, the technology has been favored by investment companies, and commercial development will be carried out in China. The person in charge of the investment company said that the main reason for his investment in this technology is an innovative technology with pricing power and core competitiveness.
Recently, Zhang Jianjun has been very busy. He is establishing Guangdong High-altitude Wind Energy Technology Co., Ltd. in Guangdong, intending to gradually move American companies to China. At the same time, the first high-altitude wind energy research center and wind tunnel laboratory will be established in Guangdong, and the first 100,000-kilowatt high-altitude wind power generation system will be built in Guangdong. He revealed that the power generation cost of a 100,000-kilowatt system is about 0.2 yuan/kWh. In addition, if all goes well, during the Shanghai World Expo next year, Tianfeng’s first prototype in China will officially meet with the public.

Towards differentiation

Obviously, Zhonglu shares no longer want to increase investment in the bicycle industry, but just want to use it to stabilize the basic market. As early as 7 years ago, the company was telling another grand story-high-altitude wind energy.

In 2014, Zhonglu Co., Ltd. (600818.SH) acquired and increased its capital at a cost of 70 million yuan to take over the high-altitude wind energy company under the actual controller Chen Rong. At that time, the company had been established for 6 years, had no income and continued to lose money.

Zhonglu shares stated that the company has developed and mastered the most cutting-edge power generation technology-“Tianfeng” wind power technology. This technology can make up for the shortcomings of the current mature power generation technology, with high efficiency and low investment cost, which is perfect.

It has been invested in high-altitude wind energy for many years, and the company has not seen any gains. The subsidiary loses tens of millions of yuan each year, which has become a drag on the company’s performance. Moreover, with the current financial strength and profitability of Zhonglu shares, it is difficult to support long-term investment in the industry.

Since 2020, the company has been promoting fixed growth, and plans to raise 950 million yuan to invest in high-altitude power generation projects. So far, it has not been finalized yet. Six years ago, the company also planned to raise 2.5 billion yuan for a 400-megawatt high-altitude wind power project, but the project was terminated because it had not received approval from the competent authority.

In 2018, Zhonglu also planned to acquire 100% equity of Shanghai Yuemu (the parent company of Membrane Family) for a consideration of 5.6 billion yuan (later downgraded to 4 billion yuan) to transform into a cosmetics company. The major asset reorganization lasted more than a year and finally fell through.

Shanghai Phoenix has tasted the sweetness of returning to the main business of bicycles. In 2020, the company will continue to consolidate its main business. By issuing shares and paying cash, it will acquire 100% equity of Tianjin Aysec, Tianjin Tianren and 49% equity of Phoenix Bicycle for a consideration of 952 million yuan, which is expected to further strengthen the company’s bicycle industry. Market Competitiveness.
