Wu Hequan: digital technology empowering "double carbon" practice according to local conditions

Under the new development pattern, digital technology helps green and low-carbon development ,“ Count from east to west ” Engineering can optimize computational efficiency and improve energy structure , It's a push “ Double carbon ” The important embodiment of strategy . meanwhile , The park takes energy conservation and emission reduction as its goal, which needs to be adjusted to local conditions according to its own characteristics .

In recent years, the construction of new infrastructure has attracted much attention , and “ Count from east to west ” The project has triggered a heated discussion in the market . The joint four departments of the national development and Reform Commission have approved the establishment of the project in Beijing, Tianjin and Hebei 、 Changjiang delta 、 Guangdong-hong kong-macao greater bay area 、 Cheng Yu 、 Inner Mongolia 、 guizhou 、 gansu 、 Ningxia, etc 8 Start the construction of the National Computing hub node , And planned to set up 10 A cluster of national data centers .

According to statistics , since this year on , The national 10 In a cluster of national data centers , New projects 25 individual , The size of the data center is 54 10000 standard rack , The construction speed has been accelerating , The demand for low-carbon energy conservation is becoming stronger .

From the perspective of double carbon “ Count from east to west ”

Wu Hequan, academician of the Chinese Academy of engineering, said ,“ Count from east to west ” The project can optimize the layout of national computing power , Create a new digital infrastructure that supports the digital economy .

In Wu Hequan's opinion ,“ Count from east to west ” Engineering has four major meanings ： One is to optimize the efficiency of computing power 、 Second, improve the energy structure 、 Third, give play to regional advantages 、 Fourth, drive the development of the entire information technology industry chain .

In the country “ Double carbon ” Under the strategic background , Green development has become the consensus of the whole society . and “ Count from east to west ” Two important contents of the project —— Optimize computing efficiency and improve energy structure , And “ Double carbon ” Strategy is closely related .

Digital energy is the use of digital technology to empower new energy , Or promote the development of traditional energy to energy conservation and emission reduction . Digital energy will be artificial intelligence 、 Cloud computing 、 Digital technologies such as big data have been brought into the traditional energy field , Realize the digital transformation of energy infrastructure through digital technology , And then improve the operation and maintenance efficiency of energy infrastructure , So as to build green 、 Security 、 Efficient energy system .

Wu Hequan said ,“ Count from east to west ” Engineering can also drive “ Source network load storage ” Integrated linkage development , among “ Source ” It is where energy is produced ;“ network ” It is the power grid of energy ;“ Lotus ” Is the load , That is, the power user ;“ Store ” Energy storage .

Digital technology enables “ Double carbon ” practice

On the long-term path to achieve the goals of carbon peak and carbon neutralization , Digital economy and green economy will promote each other 、 Work together . With the help of digitalization , Carbon reaches its peak 、 Carbon neutralization will drive new technological progress , Leading new development mode .

For example, energy management and operation technology through the energy Internet , It can help us master wind power 、 Photovoltaic power generation , And promote the matching of power transmission and energy storage , It can reduce the loss of wind and light ; Industrial Internet combining information technology and industrial technology , It can improve quality, increase efficiency and reduce emissions ; Internet of things big data technology , It can optimize ecological management , Support carbon absorption .

Wu Hequan explained , The application of information technology can bring greater contribution to energy conservation and emission reduction in traditional industries , We should actively develop information technology . Statistics show that 2030 In, the energy consumption of information technology itself is its contribution to the energy conservation and emission reduction of traditional industries 1/10, That is to say, its positive effect is 10 Times its own energy consumption .

therefore , Industry digitalization is an important direction of energy conservation and emission reduction . Digital industrialization can better reduce the unit GDP Carbon emissions . Through the realization of digital industrialization and industrial digitalization , Be able to adjust the industrial structure , And become an important focus of energy conservation and emission reduction .

meanwhile , Optimizing the energy consumption of information technology is also a top priority , The data center needs to be intelligent , Optimize energy supply according to the demand of computing power . For example, wind power 、 Green energy such as solar energy itself is not very stable , This requires big data technology for analysis and prediction , Ensure intelligent energy provisioning and storage .

Wu Hequan said , The data center is logically a hub , But it is physically dispersed . How to realize intelligent resource allocation between data centers , This requires intelligent technology . The data center not only provides AI technology , Its own operation management also needs AI To optimize .

At present, the power consumption and carbon emissions of data centers in the whole society continue to increase , But there is still much room for energy conservation and emission reduction .“ The energy consumption of servers in the data center probably accounts for 45%, Air conditioning energy consumption accounts for 40%, We use refrigeration technology to reduce energy consumption . The climatic conditions in the western region are more suitable for natural cooling , And the supply of energy is relatively sufficient , In particular, green energy is sufficient . These are conducive to reducing carbon emissions .” Wu Hequan said .

Park landing “ Double carbon ” It needs to be tailored to local conditions

2022 The Olympic venues for the Beijing Winter Olympics were realized for the first time 100% Green electricity , In the practice of low-carbon energy 、 Low carbon venues 、 Significant carbon reduction results have been achieved in low-carbon transportation , Through a series of innovative green technologies, it successfully held a “ green ” The Winter Olympics , Become the first winter Olympics to achieve carbon neutrality .

Actually , Olympic venues are parks , Its realization “ Two carbon strategy ” It provides important reference value . The park is 70% Where economic activities take place , Industrial parks and industrial parks because of their unique Park attributes , More to achieve “ Double carbon ” The key to .

In Wu Hequan's opinion , It is understandable that the park takes energy conservation and emission reduction as its goal , But there are great challenges in cost and Technology . This requires the park to adjust measures to local conditions according to its own characteristics .

According to the relevant research data of the International Energy Agency and the school of environment of Tsinghua University ,2015 In, carbon emissions from China's industrial parks accounted for 31%, And showing a continuous upward trend , Industrial parks have become the implementation of China's precision emission reduction “ Double carbon ” The key foothold of strategic objectives .

For example, industrial parks represented by Caofeidian can use circular economy, such as heat recovery generated in the process of steel smelting, to improve energy efficiency , Low carbon can also be achieved .“ These parks are of exemplary significance in terms of technology and management mode , For example, the application of energy Internet realizes the scheduling and distribution of energy , These are not only related to the power supply network , It also involves communication networks .”

Suggestions “ Double carbon ” route

How to achieve “ Double carbon ”, Develop a roadmap for action ？ Wu Hequan believes that we need to start from three aspects .

• The first is the adjustment of energy structure , Increase green energy and renewable energy , Reduce fossil energy .
• The second is industrial structure adjustment , Reduce the proportion of high energy consuming industries , Develop strategic emerging industries and digital industries .
• The third is the digital transformation and transformation of traditional industries . Digital technology improves production efficiency , Equivalent to energy consumption reduction and energy conservation and emission reduction .

“ Digital technology in the adjustment of energy structure , It can play its role in the adjustment of industrial structure and the digital transformation of traditional industries , Energy conservation and emission reduction serving the whole society , Realization ‘ Double carbon ’ The goal is .” Wu Hequan finally said .

Conclusion

Whether it's “ Count from east to west ” Project or park construction , Green development has become a consensus , and “ Double carbon ” The realization of the goal is inseparable from the wide use of digital technology , This requires the whole society to design at the top 、 Technological innovation 、 Industrial Synergy and other multi-dimensional sustained efforts .
