The implementation of the "double carbon" goal is to allow traditional energy to develop with new energy.

Energy resources in Xinjiang. It has been proven that oil, natural gas, and coal resources are very rich, and the potential for development of wind energy and solar technology has obvious potential. Through the blessing of new technologies, in Xinjiang, traditional energy and new energy are perfect.

New energy in the oil and gas industry

The "Baili Oil Area" located in the northwest of Junggar Basin is a magnificent landscape of Xinjiang's petroleum industry.

The oil collection machine in the landscape drives its weekly work is thermal power based on coal -fired power generation.

At present, Xinjiang Oilfield is conducting a pilot test, which is unable to reach the power grid or the remote exploration well with high construction costs of power grids.

Photovoltaic power -power energy storage equipment, the remaining electricity is stored during the day, and the energy storage equipment at night releases power, driving the oil recovery machine at night to work, showing the harmonious symbiosis of oil and photovoltaic power generation.

Promote the low -carbonization of traditional fossil energy mining. In June this year, Xinjiang Oilfield tried to use the residual heat power generation and carried by crude oil to generate.

Xinjiang Oilfield Wind City Oilfield Operating Area has my country's largest super thick oil collection, and it is also the "big household" consumes energy consumption of thick oil development energy. During the development of the oilfield, crude oil mined by steam throughput technology has the characteristics of high temperature and carriers to collect liquids, which requires a large amount of cold source balance.

The residual heat power generation projects carried by crude oil mining can recycle nearly 130,000 tons of steam each year. At present, the daily power generation is stable at about 17,000 kWh, which can ensure that 2,100 households use electricity daily. It is predicted that the annual reduction of 7,900 tons of carbon dioxide, saving about 230,000 tons of cold and cold sources.

Not only crude oil mining is low -carbon, but also uses green low -carbon energy.

At the end of last year, my country's first 10,000 -ton photovoltaic green hydrogen demonstration project in Xinjiang was tightly promoted the construction of hydrogen manufacturers. "The hydrogen storage tank has been installed, and the anticorrosive material is being brushed. The progress of the project has been completed by 70%. It is expected that the first production line at the end of October can produce green hydrogen." Said Fan Linsong, the person in charge of the project.

This demonstration project is transmitted by photovoltaic power generation electrolytic hydrogen. The green hydrogen produced is transmitted to the Sinopec Tahe Refining Co., Ltd. through the pipeline to replace the company's existing natural gas fossil energy hydrogen. It is expected to reduce the carbon dioxide of 485,000 tons per year. This is the first typical demonstration item of Sinopec to run through the full process of greening, green electricity transmission, green power transmission, green electrical hydrogen, hydrogen storage, hydrogen hydrogen refining and other green hydrogen production. After the project is put into production, it will create a new development path of green hydrogen refining and chemical, and it will have a significant demonstration effect on the large -scale use of green hydrogen hydrogen hydrogen to achieve the use of green hydrogen hydrogen hydrogen.

Carbon dioxide becomes a treasure

Implement the "double carbon" goal, and use CCUS/CCS (carbon capture, utilization and sealing/carbon capture and sealing) technology in Xinjiang to reduce fossil energy carbon emissions, which is given high hopes.

The CCUS project carried out by Xinjiang Oilfield is to capture carbon dioxide from a refined enterprise in Karamay, and pull it to the oil well injecting after purifying, compressed, and liquefied, driving crude oil mining, and also achieved carbon dioxide geological storage while adding oil.

Since 2015, Xinjiang Oilfield has preferably preferably conduct on -site experiments such as carbon dioxide driving, carbon dioxide anterior increase in carbon dioxide, and carbon dioxide throughput. The cumulative injection of over 380,000 tons of carbon dioxide is cumulative. Save about 300,000 tons of carbon dioxide, which evidenced the feasibility and safety of the Junggar Basin to carry out carbon dioxide oil -driven oil. As a result, the "CCUS Xinjiang Mode" in the Junggar Basin has gradually formed.

The Junggar Basin is suitable for the development of CCUS to develop geological reserves of more than 1 billion tons, which can add about 200 million tons of recoverable reserves, and can be buried for nearly 400 million tons of carbon dioxide. At the same time, the Junggar Basin also has the potential of more than 500 million tons of carbon dioxide salted water layer.

Focusing on the "double carbon" goal, Xinjiang Oilfield has formulated a long -tons CCUS/CCS vision plan. It is planned to achieve 10 million tons/year -old oil -driven oil, 10 million tons/year salt water layer buried and basin carbon dioxide pipes in the basin construction target of the basin of the basin of the basin of the basin. Contradiction between transformation and upgrading and the construction of ecological environment.

At present, Xinjiang has built 4 carbon capture factories, and two factories are about to be put into operation. The captured carbon dioxide is extended to the coal chemical and thermal power industry in addition to the oil refining industry, which will make a broad space for Xinjiang carbon reduction.

So far, the CCUS project will be fully launched in Xinjiang Oilfield, Northwest Oilfield, Tarim Oilfield, and Tuha Oilfield.

Dai Minhan, an academician of the Chinese Academy of Engineering and a professor at Xiamen University, predicts that the three major basins in Xinjiang, the saltwater layer, oil collection and non -mined coal seams, and the amount of carbon solidarity can reach 69 billion tons. "In Xinjiang, the development of the CCUS/CCS industry is huge." Dai Minhan said.

Coal oil and gas scenery tells stories together

In the past, the utilization and development of energy usually spoke to each other and became a system.

Wu Qiang, an academician of the Chinese Academy of Engineering and the chairman of the China Energy Association, said: "Xinjiang has rich traditional fossil energy and new energy -based new energy. The advantage of new energy is clean and low -carbon, but it has a intermittent and unstable disadvantage. When entering the power grid, it will challenge the security of the power grid. Xinjiang can respond to risk challenges by regulating technology, adjust the peak by bundling thermal power, or use battery energy storage, light thermal energy storage, hydrogen energy storage and other energy storage technologies to allow energy storage technologies to allow energy storage technologies to allow energy storage technologies to make The unstable new energy has become stable. "Wu Qiang suggested that Xinjiang should use new technologies to couple in traditional energy and new energy.

In terms of energy storage technology, most of the new energy projects invested in Xinjiang in the past two years are mostly integrated projects in the source of the source network, and almost all have their own "charging treasures". Through energy storage equipment, some remote towns or industrial parks with insufficient power supply will use stable new energy sources.

At present, in the Petroleum Petrochemical Industrial Park in the Korla Shangku High -tech Industrial Development Zone, the integrated source of the source of the source network is under construction. It provides green power for the park enterprises through photovoltaic power generation to reduce energy consumption indicators. "The carbon dioxide energy storage technology is used. Carbon dioxide is captured from the exhaust gas discharged by industrial enterprises in the park to compress it. The purpose is to make the park a green zero -carbon industrial park." Xu Zheng, the person in charge of the project, said.

Not long ago, at the Academician Forum of the "Silk Road Economic Belt core area -the core area of ​​the Silk Road Economic Belt" in Xinjiang, Luo Boxiong, the secretary of the Party Committee and Chairman of China Electric Power Engineering Consultant Group Co., Ltd. , Coal power, coal chemical industry and other industries are one of the ideal test places for implementing the "dual carbon" strategy and traditional energy and new energy coupling. It can first create an integrated demonstration project with distinctive characteristics of coal, oil and oil and gas landscape storage to explore the scenery of the scenery Storage, landscape hydrogen storage and other model combinations, focusing on the national "three bases and one channel" strategy, coordinate the advantages of energy distribution, and create a clean energy demonstration zone.
