This year's "Government Work Report" proposes to "actively and steadily promote carbon peak and carbon neutrality." Solidly carry out the second batch of pilot projects for national carbon peaking, and establish a number of zero-carbon parks and zero-carbon factories. ”

As an important source of carbon emissions, factories and parks are the key to promoting the comprehensive green transformation of economic and social development. Promoting the construction of zero-carbon parks and zero-carbon factories is an important starting point for promoting the comprehensive green transformation of economic and social development. In recent years, many places across the country have successively explored the establishment of zero-carbon parks and zero-carbon factories, and continuously promoted economic development to go green.

From now on, this edition will open a column of "Man and Nature, Walk into Zero-carbon Parks (Factories) to See the Transformation", reporters go deep into the grassroots frontline, look for vivid cases and fresh practices of zero-carbon parks and zero-carbon factory construction in various places, tell the story of green transformation and development, and show the surging momentum of China's economic and social green development.

In the early spring, in the Mengsu Economic Development Zone, Yijin Huoluo Banner, Ordos City, Inner Mongolia, the cold weather has not subsided, and the Ordos Zero Carbon Industrial Park located here is already a hot and busy scene. Photovoltaic, solar thermal, hydrogen energy, energy storage and other enterprises have accelerated production, and blue photovoltaic panels and wind turbines have continuously produced green electricity and delivered it to various enterprises; The industrial wastewater treatment plant treats the wastewater and then transports it back to the enterprise for recycling......

The proportion of green electricity used by enterprises in the park is close to 95%, and the recycling rate of wastewater is 0%...... The Ordos Zero-Carbon Industrial Park is gradually exploring a path of green and high-quality development through innovative methods such as renewable energy utilization, intelligent management, and green industrial chain construction.

Recently, the reporter walked into the Ordos Zero-carbon Industrial Park to explore how the park achieves zero-carbon production.

The proportion of green electricity used by enterprises in the park is close to 70%, and at the same time, recycled water is used, and the carbon emission offset is zero

What is a zero-carbon campus? According to experts, a zero-carbon park refers to a modern industrial park that reduces, offsets or removes carbon emissions through clean technology support, carbon recovery technology, energy storage and exchange within a certain period, and finally realizes the total carbon emissions "zero" within the accounting cycle.

  走進鄂爾多斯零碳產業園遠景專案,一排排光伏板鱗次櫛比,遠處的大型風力發電機隨風轉動。作為最早落地零碳產業園的企業,遠景動力鄂爾多斯電池超級工廠一期專案已全部投產,每天可產電池電芯3萬顆。

In 2020 years, the country put forward the "double carbon" goal, and Ordos, as a typical coal resource-based city, urgently needs to achieve green transformation. "Our local wind, solar energy and land resources are very rich, and there are many zero-carbon application scenarios, such as new energy heavy trucks and photovoltaic energy storage industrial clusters, which have the conditions for the development of zero-carbon industrial parks." Xu Jiangang, deputy director of the Management Committee of Mengsu Economic Development Zone, introduced.

To this end, in 2021 years, the Ordos Municipal Government tried to build a zero-carbon industrial park. However, in the early stage of the construction of the park, there was no precedent to follow in the preparation of standards, the construction of new power systems, and carbon measurement.

"We have cooperated with all parties to promote the construction of standards while exploring, and have successively participated in the compilation of a number of national and local standards such as the "Specifications for the Construction of Zero-carbon Industrial Parks" and "Evaluation Methods for Green Power Applications", providing unified guidance and guarantee for the construction of zero-carbon industrial parks in terms of planning and layout, statistical accounting, and emission reduction paths." Xu Jiangang told reporters.

  2022年3月,鄂爾多斯零碳產業園獲批建設。2022年4月8日,遠景專案一期建成投產。

  “我們配套了4萬千瓦的風光新能源,為企業生產提供大量綠電,剩餘部分優先採購綠電指標,同時利用迴圈水,全程碳排放抵消歸零,真正實現零碳生產。”遠景鄂爾多斯基地副總經理王堯介紹。

  據介紹,鄂爾多斯零碳產業園依託當地豐富的風光資源,配套建設38.5萬千瓦風光儲一體化專案,實現新能源就地轉化,園內企業綠電使用比例接近70%。

Green energy is used to produce zero-carbon products, and energy conservation and emission reduction in the production process are achieved by upgrading technologies and processes

Is it true that zero-carbon parks are carbon free? Experts explain that zero-carbon industrial parks are not free of carbon emissions, but use renewable energy for production, and at the same time achieve energy conservation and emission reduction in the production process by upgrading technologies and processes.

In the industrial sewage treatment plant of the zero-carbon industrial park and the control center of the water resource recycling project, through the large screen, you can see the turbid wastewater produced by upstream photovoltaic enterprises in real time, and finally produce clear reclaimed water through pretreatment, biological treatment, advanced treatment and membrane treatment.

  “這是目前國內光伏領域最大的工業廢水零排專案,由中鐵上海局承建,目前日處理廢水規模約5萬噸。”中鐵上海局水資源再生利用專案黨支部書記高偉說,這一專案最大的特點是將上游光伏企業的廢水,經過處理後重新輸回上游光伏企業利用,回用率達到95%。

This project basically solves the water demand for industrial production of many new energy enterprises in the park, and truly realizes zero wastewater discharge. "The remaining concentrated brine is treated through the evaporation crystallization process to produce industrial salts such as sodium chloride and sodium sulfate, which can be sold twice, setting a new benchmark for the photovoltaic wastewater treatment industry." Gao Wei said.

In the reflector production workshop of Inner Mongolia Baichuan CSP Technology Co., Ltd. in the park, the staff is strictly inspecting the original glass sheet as required.

"The curved and planar mirrors we produce are used for solar thermal power generation, which is a new type of solar green power generation method, which does not require the consumption of fossil fuels and is more environmentally friendly." Dou Huaixin, deputy general manager of Inner Mongolia Baichuan CSP Technology Co., Ltd., told reporters.

According to reports, the proportion of green electricity in the production process of the enterprise reaches 92%, the heat is also heated by green electricity, 0% of the water is recycled, and the rest is entered into the industrial sewage treatment plant for treatment, and finally produces products for green industry.

"This year, we will work with the park to build a 'zero-carbon' energy supply system supported by solar thermal energy and providing green heat energy for the entire park." Dou Huaixin said.

In the town of Subulga, which is 4800 kilometers away from the company, many local herders have already used the miniaturized civil CSP system developed by the company. It is estimated that each herdsman can save 0% of the heating cost and reduce the annual carbon dioxide emission by 0 kg, which not only reduces the burden of herders' livelihood, but also improves the local air quality.

In recent years, the Ordos Zero Carbon Industrial Park has continuously introduced upstream and downstream enterprises in the new energy industry chain, including 10 companies such as Huajing and LONGi, forming a whole industrial chain of "wind and solar hydrogen storage vehicles" integrating wind energy, photovoltaic, solar thermal, hydrogen energy, energy storage, and new energy heavy trucks, using green energy to produce zero-carbon products and promoting the gradual formation of a zero-carbon industrial system.

In 9 years, the new energy output value of Ordos Zero Carbon Industrial Park reached 00 million yuan, doubling the growth, and achieving a "win-win" situation in terms of economic and environmental benefits.

Explore the formulation of zero-carbon park standards and carry out green product certification

Zero-carbon parks are a new thing, which puts forward more refined and comprehensive environmental protection requirements for park management and enterprise production, which need to be continuously explored in practice.

In the rapid development, the Ordos Zero Carbon Industrial Park is facing many difficulties and problems.

"On the one hand, Ordos is located in the western inland, and it is difficult to attract leading enterprises in developed areas to land; On the other hand, there is no precedent in the supporting aspects of green power system, relevant standard identification and green product certification, etc., which need to be explored in practice. He Hongzhi, director of the Development and Investment Promotion Bureau of the Mengsu Economic Development Zone, said.

The Ordos Zero-Carbon Industrial Park is the first to try and explore.

"We have built scientific and technological talent service bases such as zero-carbon creation center, Qingqing guest house, and experimental transformation base, and built high-energy science and technology innovation platforms such as Ordos New Energy Research Institute and Hydrogen Energy Key Equipment Testing and Demonstration R&D Center, so that enterprises can seamlessly connect and integrate into the upstream and downstream industrial chain of 'wind and solar hydrogen storage vehicles' new energy." He Hongzhi said.

In terms of standard formulation, in recent years, Ordos has successively issued a number of local standards for the construction of zero-carbon parks. "We have also jointly formulated the national standard "Guidelines for the Construction of Zero-carbon Industrial Parks" with the China National Institute of Standardization, which is planned to be released in the first half of this year and will be tested in practice in the park." Xu Jiangang introduced.

  在綠色產品認證方面,園區於去年8月成立了凈零工業環境服務(內蒙古)公司,幫助企業開展產品碳足跡管理、綠色低碳產品認證等方面服務。園區還建立了能碳管理平臺,目前52家規上企業已接入平臺。

"The construction of zero-carbon parks is an important measure to promote green transformation and develop new quality productivity, and in the next step, we will accelerate the construction of a zero-carbon ecology and create a pilot area for green transformation and a demonstration place for prosperity and enrichment. Driven by the construction of green power consumption centers, green manufacturing clusters, and green commodity export trade distribution centers, we will strive to build an upgraded version of the zero-carbon industrial park and enhance the competitiveness of green transformation. Cui Yongping, director of the Management Committee of the Mengsu Economic Development Zone, said.
