Under the double carbon target, what are the new trends of clean energy equipment?The amount of information in this meeting is very large

Economic Observation Network reporter Zhang Xiaohui, August 27th to 29th, 2022, the World Clean Energy Equipment Conference was held in Deyang, Sichuan. This is one of the few world -class forums in Deyang.

Top domestic and foreign energy experts exchanged for the "Renewable Energy + Energy Storage" innovation application and demonstration promotion sub -forum and clean energy power generation equipment development. This is also a event for academicians, experts, private enterprise experts, and foreign enterprise experts to communicate with each other at home and abroad.

"Renewable Energy+Energy Storage" exploration

On the afternoon of August 27th, the "Renewable Energy + Energy Storage" Innovation Application and Demonstration Promotion Forum was a popular sub -forum of this conference. At the forum, the guests discussed the renewable energy and storage under the double carbon target. Energy research and trends, and how to better develop the "renewable energy + energy storage" model in the future.

Lei Xiaochang, an academician of the National Academy of Engineering of the German National Engineering, Carbon and Chief Scientist of Southwest Petroleum University, and Dean of the Tianfu New Energy Research Institute, said in his speech "Edated Coupling Coordination, Help New Electric Power System" China's solemn commitment to the world is carbon neutrality is "a wide and profound economic and social systematic change", which is related to the sustainable development and constructing the community of human destiny for the Chinese nation.

Lei Xianzhang believes that the coordination of electro -hydrogen coupling is an important starting point for achieving dual carbon targets (that is, carbon peak carbon neutralization). Lei Xianzhang said that we are currently facing two challenges: First, the total capacity of wind and light power generation installed in 2030 will reach at least 1.2 billion kilowatts (the industry is estimated to reach 1.5 billion to 2 billion kilowatts), at least three times the existing installation capacity Is the power grid the only way to eliminate optoelectronics? The second is to build a new power system with new energy as the main body under large -scale new energy conditions. It is necessary to ensure that the power balance and dynamic stability of the full -time field under the high proportion of the power grid clean power are the prerequisite for the power grid to achieve first and then break.

Hu Bo, deputy secretary -general of the China Smart Energy Industry Alliance, said in his speech that due to the short time and heavy tasks of China's double -carbon target, and taking into account economic development and low -carbon goals, the difficulty of energy transformation and new power system construction must be greatly increased. It is mainly reflected in four aspects: the safety and stability of the power system will withstand huge pressure; while actively reaching the peak, the power system also needs to make overall development and emission reduction; to ensure that the economic operation of the power system is becoming more difficult; The end of the emissions.

Hutbo uses multiple industries to show that my country's new energy storage industry is in the transition stage from R & D, demonstration to the initial stage of commercialization. In terms of sexual progress, the market size has expanded steadily, and its support for energy transformation has initially emerged. However, there are still many problems and challenges in the development process.

According to Wu Yun, deputy general manager of China Energy Construction Group Co., Ltd., large -scale energy storage applications will become an important symbol of the new power system. The new power system is supported by safety, green, and efficient high -quality development, and supports technological innovation and institutional mechanism innovation. The network and the lotus are deeply integrated.

At the forum, Fang Yu, deputy general manager of Dongfang Electric Group Dongfang Auto Turbine Co., Ltd., introduced the system principle of carbon dioxide energy storage. Carbon dioxide storage energy has high energy density, large capacity, long energy storage time, safe and reliable project construction, and does not rely on geological conditions for project construction. The characteristics of short construction cycle. At present, electric-electric conversion efficiency is 60%to 75%.

Fang Yu showed the world's first carbon dioxide + flywheel energy storage demonstration project that has been built in Dongqi Plant. It smoothly fluctuates the power grid through the power storage station with frequency adjustment and peak adjustment capabilities, solving intermittent problems to achieve the safe operation of the power grid, creating a new new energy station new energy station. concept.

Ying Guangwei, the president of the Intelligent Electric Power Commission of China Electric Power Development Promotion Association, introduced the current new type of energy storage development in his speech: as of the end of 2021, the global power storage of electric power energy storage was 209.4GW, and China ’s cumulative investment and installation scale was 46.1GW. , Accounting for 22%of the total global market scale, the cumulative installed scale of new energy storage is 5729.7MW, of which the scale of lithium battery installed capacity is the largest, accounting for about 90%; many China's energy storage technology routes are moving towards the application of hundreds of mega watts. Including the first trial operation of the parallel grid adjustment of the 100M tile compressed air storage project, the 100 MPA liquid flow battery project is under construction.

Zhang Fan, director of the Science and Technology Innovation Department of China Electric Equipment Group Corporation, proposed at his speech that there are four major dilemmas in energy storage applications.

The first is the predicament of value. As an middlemen in the energy sources, energy storage is difficult to reflect, and the business model has not been completely formed.

The second is the economic dilemma. Energy storage economy is still difficult to meet the requirements of large -scale and large -scale promotion in the short term.

Third, technical and engineering dilemma. The performance (efficiency, attenuation) of energy storage systems, large differences in the range of detection, low degree of attention, and unclear responsibility interface.

Fourth, the dilemma of safety hazards. The hidden dangers of energy storage are still existed, and standardization construction needs to be improved.

New trend of clean energy power generation equipment

At this World Clean Energy Equipment Conference, clean energy power generation equipment has attracted much attention. The "New Trend of the Development of Clean Energy Power Generation Equipment" forum was held on the morning of August 28.

Liu Jizhen, an academician of the Chinese Academy of Engineering, gave a speech in a remote video. Liu Jizhen said that the overall idea of ​​China's energy transformation is: fossil energy cleaning, clean energy scale, and comprehensive energy comprehensive energy. Fossil energy cleaning refers to the development of coal and other fossil energy clean and efficient development and utilization technology to reduce the consumption and proportion of fossil energy; clean energy scale refers to the development of renewable energy and advanced nuclear energy technology, which greatly improves the proportion of non -fossil energy; The integrated energy of species refers to increasing the proportion of electric energy in terminal energy consumption and breaking through comprehensive energy technologies such as power grids, energy storage, and hydrogen energy.

Norman, vice president of Siemens Energy Co., Ltd., said that in order to achieve dual carbon targets, China needs to build a clean and low -carbon safe and efficient energy system and build a new power system with new energy as the main body.

Norman focuses on hydrogen energy. He said that hydrogen does not produce carbon emissions, but it has unique physical characteristics and requires agile design and testing. At the same time, the equipment provided by Ximenzi Energy, and the National Power Investment Jingmen High -tech Zone Natural Gas Multi -Linking Energy Project.

On December 26, 2021, the National Electric Power Investment Jingmen Green Power Plant was transporting a combustion engine and successfully achieved 15%hydrogen -mixed combustion transformation commercial operation. The unit has the compatibility capabilities of natural gas and natural gas hydrogen doping. This is the first joint cycle of hydrogen and combustion in natural gas commercial units to carry out hydrogen -borne and thermoelectric supply demonstration projects. This project is divided into two phases: 15%hydrogen mixing burning at the end of December 2021; 30%hydrogen mixing burning at the end of 2022, at that time, the crew will have the flexibility of freely switching at 0%to 30%hydrogen. Essence

Norman said that for a new combined recycling power plant that does not need to be doped immediately, we are optimizing the configuration to consider the future hydrogen transformation ("hydrogen cucumber power plant").

Qin Haiyan, vice chairman of the World Wind Energy Association, focused on the application of wind power equipment in new energy.

Qin Haiyan said that the scale of Chinese wind power capacity has grown from 6MW in 1992 to 2021 to 340 million kilowatts. Technical mastery has also from technology introduction, joint development, independent research and development, and global leading. Chinese wind power installed machines have ranked first in the world for 10 consecutive years.

China's wind power technology has continued to improve, and single -machine capacity, impeller diameter, and wheel height have continued to increase. At present, the height of the wheel hub of wind power units is up to 170 meters. The maximum diameter of the land wind wheel has exceeded 190 meters. Technically, China's wind turbines can meet the development needs of various environmental climate areas such as desert, ocean, low temperature, high altitude, low wind speed, typhoon, etc. Among the global TOP15 wind power engine manufacturers, there are 10 in China, with 53.5%installed capacity.

Qin Haiyan said that the installation of clean energy in 2025 will become the dominant energy source. Wind power installed capacity will exceed 540 million kilowatts. By 2030, the wind power will exceed 800 million kilowatts, and the wind power will reach 2.5 billion kilowatts in 2060. The three major markets will get a second flight. They are offshore wind power markets, southern Middle East markets, and "three north" markets.

"By 2050, the cost of global wind power will drop by 37%to 49%." Qin Haiyan predicted.

Zang Pengfei, general manager of the Technology Center of Jingke Energy Co., Ltd. introduced the decontamination of the construction department. He said that the proportion of terminal energy consumption in the construction industry was gradually transformed from fossil fuel to electrification, which requires a widely layout and application of green power and electrification. Jingke Energy won the 5MW BIPV photovoltaic component project of the Dubai Hydropower Administration's new headquarters building. After the project is completed, it will become the world's largest and most high monopotic BIPV system building.

Liang Quanwei, deputy general manager of Dongfang Electric Group Dongfang Electric Co., Ltd., focused on introducing the industrial situation of pumping storage energy storage. More than 1.2 billion kilowatts.

Pumping storage has ushered in explosive growth. The medium and long -term development plan is: 4.21 kilowatts of key implementation projects and 305 million kilowatts of reserve projects. By 2035, the total scale of pumping storage power stations will reach 300 million kilowatts.

The construction of clean energy bases represented by the integration of water landscape and integrated source of source network loads is gradually becoming the mainstream model of future energy development.
