The Ministry of Industry and Information Technology recently announced the “Fourteenth Five-Year Plan for Industrial Green Development”, expounding the overall idea of ??industrial green development during the “14th Five-Year Plan” period, and clarified development goals and specific tasks such as continuous decline in carbon emission intensity and significant reduction in pollutant emission intensity. arrange. In particular, it is proposed to drive changes in production methods through digital transformation.
During the “14th Five-Year Plan” period, how can digital technology contribute to the green development of industry? The reporter conducted an interview on this.
The plan points out that by 2025, significant results will be achieved in the green and low-carbon transformation of industrial structure and production methods. Green and low-carbon technology and equipment will be widely used, energy resource utilization efficiency will be greatly improved, and the level of green manufacturing will be comprehensively improved. It is clear that new generation information technologies such as the Industrial Internet, big data, and 5G will be used to improve energy, resource, and environmental management, deepen the digital application of the manufacturing process, and empower green manufacturing.
“Digital transformation is a major trend. The deep integration of new generation information technology and traditional industries is becoming a new driver for industrial energy conservation, carbon reduction and efficiency enhancement.” said Wang Xiaoyang, deputy director of the Energy Conservation and Comprehensive Utilization Department of the Ministry of Industry and Information Technology. Currently, power, steel, petrochemicals, etc. A number of typical applications have emerged in traditional industries where digital technology transformation drives the systematic improvement of energy resource efficiency.
In the first ten days of November, in the factory area of ??Hezhong New Energy Automobile Co., Ltd. in Tongxiang, Zhejiang Province, employees of the company were busy debugging the prototype vehicles that had just rolled off the assembly line. The staff of the power supply company completed the transformer capacity increase on the side.
Facing the increase in electricity consumption brought about by the rapid growth of production capacity, the State Grid Zhejiang Tongxiang Power Supply Company grasps electricity demand through big data such as energy consumption and production, provides personalized services, and proposes new photovoltaic and other clean energy electricity plans. Help companies reduce emissions.
Cooperating with UFIDA to build a smart factory, and optimizing production scheduling through the load scheduling system, the consumption of energy and power in the production line of the Fujian Petrochemical Plant has been greatly reduced.
The application of technologies such as big data and industrial Internet in green production has been continuously deepened.
“During the ’14th Five-Year Plan’ period, we must pay more attention to tapping the potential of digital technology in terms of energy saving and emission reduction.” The in-depth integration of links such as, recycling and utilization, promotes enterprises and parks to implement full-process and full-lifecycle refined management, and promotes the improvement of energy and resource efficiency systems.
“Among them, it is important to promote the intelligent perception of key process equipment in the manufacturing process, and realize intelligent analysis and fine management of the production process.” Wang Xiaoyang said that it will accelerate the cultivation of a number of typical application scenarios for energy conservation, carbon reduction, water conservation and other key areas. Promote standardized “Industrial Internet + Green Manufacturing” solutions.
Accelerating the deployment of green and intelligent data and computing facilities and reducing the energy consumption of new infrastructure such as data centers are also one of the directions.
PUE is one of the indicators to evaluate the energy efficiency of a data center. The closer the PUE value is to 1, the higher the greenness of a data center.
The “Glacier” phase change cooling technology developed by Baidu introduces the oil-free concept into the refrigeration cycle system, which increases the energy efficiency of more than 40% compared with the traditional chilled water system. In 2020, Baidu’s self-built data center has an average annual PUE value of 1.14.
The Ministry of Industry and Information Technology has previously made it clear that it will take three years to basically form a new data center development pattern with reasonable layout, advanced technology, green and low-carbon, and the scale of computing power that is compatible with the growth of the digital economy. In terms of future data center emission reductions, the Ministry of Industry and Information Technology has set an indicator that by the end of 2025, the PUE value of newly built large and ultra-large data centers will drop below 1.3.
In addition, the Ministry of Industry and Information Technology also proposed that it will coordinate the green and low-carbon basic data and industrial big data resources, establish a product life cycle green and low-carbon basic data platform by industry, and carry out carbon footprint, water footprint, and environmental impact analysis and evaluation based on the platform data to support Enterprises and parks promote green promotion through digital transformation.
