Nanxun and Fuzhen Sanji Fish Pond and photovoltaic power generation symbiosis

Green is the background of Zhejiang.

17 years ago, the green mountains and green mountains were born in the land of the Jinshan Yinshan.

From August 15th to 16th, a national conference hosted by the China Science and Technology Association and the Zhejiang Provincial Government, a high standard and high -standard national conference, 20122 China Green Low -Carbon Innovation Conference was held in Huzhou, 60 academicians, and relevant national ministries and commissions are responsible for A total of more than 260 people attended the meeting. They have collided and exchanged in depth, and they seek to develop the future of sustainable development in China. In the context of continuous high temperature and energy tension in many places in the world, these issues are particularly important and urgent.

The opening ceremony of the opening ceremony of the China Green Low Carbon Innovation Conference

The land of 100,000 square kilometers is struggling to write a wonderful answer sheet of green, low -carbon, and rich. How to promote green low -carbon innovation? "Scientific and technological innovation is a key variable." Wang Jinnan, chairman of the conference and academician of the Chinese Academy of Engineering, broke the true meaning.

The blending of ecological harmonious villages and green carbon

Open the color palette of Zhejiang's scientific and technological innovation, and it is a touch of green.

In the summer wind, the bamboo sea in Shanchuan Township, Anji County, a 40 -meter -high woolen bamboo forest carbon exchange session observation tower stands in the middle.

With the help of scientific detection instruments such as the built -in radiation sensor, light three -dimensional ultrasound wind speed instrument, and carbon dioxide water vapor analyzer, this general volume observation tower can collect and transmit ecological data such as carbon dioxide concentration of different crown layers of bamboo forests in real time, providing for the monitoring and measurement of bamboo forest carbon exchange monitoring measurement measurement The benchmark.

"Bamboo Forest Carbon Exchange", many people's nouns that are slightly sparse, have become a new model of development of Dali Village, Anji Shanchuan Township.

In December 2021, Anji officially launched the "Two Mountains" bamboo forest carbon exchange collection and storage center, a full chain of "Forest Land Circulation -Unified Management -Carbon Exchange Reservoir -Platform Trading -Benefits".

Dali Village is the first batch of "crabs". "After the carbon transfer of 5,300 mu of bamboo forest was transferred to the trading center, we received 294,000 yuan in one -time and storage deposits in three years." The profit is returned to the village proportion, and the local people are inspired. Right now, in order to improve the carbon ability of bamboo forests, many villagers have joined the forest protection team of Maozhu professional cooperatives in Dali Village to help trim bamboo shoots and maintain Maogu. In just half a year, the large -scale circulation work of this "point bamboo" came to an end. According to estimates, after the rotation of 870,000 acres of hair bamboo forests in the county is expected to add about 340,000 tons of carbon exchange each year.

Looking at the blue sky, drinking a scoop and blue water, and stepping on the pure land of the side, such a poetic life will not come out of thin air -June 2021, the Provincial Party Committee's Science and Technology Strong Provincial Construction Leading Group issued the "Zhejiang Carbon Peak and Carbon Carcan and Technology Innovation Action Plan, in June of this year, issued the "Special Action Plan for the" Blue Carbon "Science and Technology Innovation in Zhejiang Province, and the roof designed on the top -level was overwhelmed.

Xie Zhiyuan, Secretary of the Party Group and Vice Chairman of the Provincial Association of Science and Technology, believes that green low -carbon technology is the largest endogenous power to expand "green water and green mountains is the golden mountains and silver mountains". To realize the transformation of "green technology" to "green economy", the first way to take the first way to ecological priority and green and low -carbon is the inherent requirements for the modernization of builders and nature.

The fish lived in water and grass, and the birds chose a good wood. For Zhejiang, looking back at the green mountains and mountains, it is also a return.

In Nanxun District, Huzhou City, the thousand -year mulberry fish pond system and clean energy use form a harmonious ecological beauty map. More than 400,000 solar plates are located on more than 4,200 acres of fish ponds in Silian Village, Hedong Village, and Yangdong Village. The scene is spectacular.

"When I was a kid, I often planted mulberry silkworms with my mother here, poured silkworm pupa and silkworm sand into the ponds to feed fish, and other humus and fish dung converged into the bottom of the pond to become silt, and then shoved to fertilize the mulberry tree. I only feel that the work of doing farm work is hard. When I grow up, I know the green carbon principle contained in it. "Yang Shenghui, the secretary of the party branch of the Diang Village of Hezhen, said with a smile.

The mulberry fish pond contains the ecological wisdom of Zhejiang ancestors, which is heavy and not silent. Ye Shenghai, a researcher at the Provincial Academy of Agricultural Sciences, told reporters that Sanji and Fish Pond used mutually beneficial symbiotic relationships and effectively solved the problem of zero emissions through material circulation.

This is a fresh but not vulgar green. This fishing and light complementary project has an annual power generation of more than 200 million kilowatt -hours. Based on the annual electricity consumption of 2,000 kWh of ordinary families, it can meet the electricity consumption of 100,000 households for one year, which is equivalent to saving 64,000 tons of standard coal.

The ancient taste is compatible with innovation and elegance, and the swimming fish in the pond, as well as green carbon innovation.

Cleaning energy to achieve the problem of dual carbon targets

In Beijing Qingyuan Street, a buse of a hydrogen fuel cell has just "drinked" the energy, slowly drove out of the platform, and packed lightly. It turned out that it just took about 10 minutes to fill it, neither diesel nor electric energy, but hydrogen.

"At present, the hydrogen fuel cell vehicle is loaded with a 70MPA hydrogen cylinder, which is equivalent to 700 atmospheric pressure. It can run more than 500 kilometers at a time. The mileage can be comparable to fuel vehicles." Academician of the Chinese Academy of Engineering and professor at the School of Energy Engineering of Zhejiang University Zheng Jinyang introduced.

The hydrogen storage tank of hydrogenation of hydrogen in the hydrogen cylinder is a 98MPA hydrogen storage tank, which comes from the "key technology and engineering application of hydrogen -scale purification and high -pressure storage equipment" led by Zheng Jinyang. As the winning results of the second prize of the National Science and Technology Progress Award of 2020, it leaped from 35MPa to 98MPa in the can of the can, making my country a few countries with independent research and development capabilities with hydrogen storage high -pressure containers. The land of the river now has a high temperature of 40 degrees Celsius. "The climate mode is clear: Is the earth heating up? Yes. Is it because the greenhouse gas content in the atmosphere increases? Yes. Can it be explained by natural factors? No. Human emissions are rising temperatures to rise. What are the reasons? Yes. "At the Nobel Prize Awards ceremony in 2021, the Nobel Prize Committee used 4 questions to explain the research of Shimuo Lang, one of the awards.

If the concentration of the atmospheric carbon dioxide doubles, the average temperature of the earth's surface will increase by about 2.4 ° C -this is the conclusion that he and the collaborators establish a climate model.

Strive to achieve carbon peaks by 2030, and achieve carbon neutrality before 2060 -with a lot of energy to achieve my country's double carbon commitment, the Chinese people have this "account" in their hearts.

"The technical system industrial system based on fossil energy will definitely undergo profound changes." During the meeting, He Kebin, an academician of the Chinese Academy of Engineering, told reporters that wind, sunlight, and hydropower were the way to break the problem -the clean energy of nature is everywhere. To describe the word, it is to eat by the sky. Can these uncontrolled energy be transformed into a chemical energy carrier like fossil fuel?

Hydrogen energy is a choice. Except for water after burning hydrogen, nothing will be left, and the combustion value is three times that of gasoline.

To achieve high safety, low -cost, large -capacity high -pressure hydrogen storage, the biggest problem is to solve the problem of hydrogen and brief prevention and control. Don't look at the volume of this hydrogen storage tank of Zheng Jinyang's team is only 1 cubic meter, it is not easy to do. To this end, Academician Zheng Jinyang led the team to first invented the in situ detection device in the in situ detection of materials in the high -pressure hydrogen environment to form a detection technology and method. Finally, the full -technology chain of the full -layer hydrogen storage high -pressure container from design, manufacturing to inspection and testing was opened.

Hydrogen, the key to the development of the world's energy development today, has emerged, and has shined on a larger stage, becoming an important fulcrum to leverage Zhejiang's energy transformation.

Perhaps, at the Hangzhou Asian Games next year, we will also see the hydrogen power unmanned sightseeing car.

The only way for scientific and technological innovation to develop green carbon development in the future

Since the "Thirteenth Five -Year Plan", 238 provincial key research and development plan projects are behind the beautiful scenery of Zhejiang in the beautiful scenery of the poetry and painting Jiangnan.

Atmospheric pollution prevention, energy conservation and emission reduction, new energy, traditional energy transformation and upgrading, forest carbon exchange ... In the laptop of the relevant offices of the Provincial Department of Science and Technology, behind the green and low -carbon projects, the "red hook "".

"We set a small goal: by 2025, we initially constructed our province's green low -carbon technology innovation system," he said.

Behind confidence, focusing on key areas such as energy, industry, and ocean "blue carbon", the Provincial Department of Science and Technology has sorted out more than 500 major technical requirements for low carbon, compiles technical roadmap, focuses on attacking the carbon and coordinated efficiency and efficiency increase technology, and obtained a batch of batch Hardcore results--

Coupling demonstration of coal electricity carbon capture and mineralization

The nation's first coal -electric carbon capture and mineralization use full process coupling demonstration project started construction in Lanxi Power Plant. The cost of CO2 absorbers developed by developed CO2 is expected to decrease by 30%;

Alibaba Cloud High Performance Cloud Computing Infrastructure The theoretical limit is approximately the theoretical limit. The average annual clean energy power is 450 million kilowatt -hours, and the carbon dioxide is reduced by 300,000 tons;

Zhejiang Agricultural and Forestry University intensively operates 15 key technologies for the improvement of bamboo forest soil to establish 15 demonstration bases, with a cumulative promotion area of ​​2 million acres and a cumulative efficiency of 1.1 billion yuan ...

"Coal can also become a clean energy source." Gao Xiang, an academician of the Chinese Academy of Engineering, said excitedly that through cooperation with Zhengneng Group and other units, the team developed high -efficiency, high reliability, high adaptability, low -cost multi -pollutant efficient collaboration with high efficiency and coordination of high -efficiency coordination. Remove the ultra -low emissions system, and finally realize the ultra -low emissions of multiple pollutants in coal -fired units under complex coal quality and complex operating conditions.

At the Jiahua Power Plant, the reporter was surprised to see the coal -fired generator set of 1 million kilowatt -hours per hour. In just a few tens of seconds, coal -fired flue gas "runs" the ultra -low emission developed by the Gaoxiang team. In the end, the concentration of the discharge of pollutants is far lower than the emission limit, and there is almost no smoke color on a chimney of more than 200 meters high, and the application of coal is cleaner.

The Baima Lake Laboratory, which was director of Gao Xiang for more than two months, has been pushed into key technologies in the fields of key technologies such as solar energy conversion and catalytic, zero -carbon energy conversion and storage, energy transformation and multi -energy coupling. Essence The leading unit Zheneng Group is the main force of energy supply in our province. Laboratory research will directly connect the industry, with a faster transformation and higher success rate. In the future, the laboratory also plans to equip investment companies, engineering companies, and industrial companies on the technical incubation chain to accelerate the industrialization of scientific research results.

"In the next 40 years, it is the time when the energy and environmental protection people's congress of the Energy and Environmental Protection of the New Era. I hope we can live up to our mission, based on China, go to the world, and make efforts and contributions to energy and environmental protection!" Gao Xiang said with emotion.

Of course, we must be soberly seen that there are still shortcomings and problems to promote the "double carbon" work.Relevant experts revealed that the current power of Zhejiang's scientific and technological innovation supports green low -carbon change power is not enough, and high -end carbon -lowering high -end talents in interdisciplinary composite carbon reduction are relatively lacking. Low (zero) carbon technology is difficult to apply.Promoting ... All problems need to be resolved urgently.The person in charge of the relevant office of the Zhejiang Provincial Department of Science and Technology said that in the future, Zhejiang will focus on the implementation of "basic cutting -edge research, key core technological innovation, advanced technological achievements transformation, enhancement of innovation platforms, the cultivation of entrepreneurship and innovation, the introductionThe eight major projects such as sustainable development demonstration and leading and cooperation with low -carbon technology ", with the goal of seizing carbon -peak carbon neutralization and technology, providing solid scientific and technological support for green low -carbon co -rich.
