Promote low-carbon transformation with energy efficiency constraints-
energy conservation in key industrial fields "rules to follow",
our reporter Gu Yang
Recently, the National Development and Reform Commission and other five departments jointly issued the "Several Opinions on Strict Energy Efficiency Constraints to Promote Energy Conservation and Carbon Reduction in Key Fields" to address energy conservation and carbon reduction, green and low carbon in key industries and data centers such as steel, electrolytic aluminum, cement, and flat glass. Transformation proposes clear goals and tasks.
Related departments issued the "Energy Efficiency Benchmark Level and Benchmark Level in Key Fields of High Energy-consuming Industries (2021 Edition)", which provides reference standards for energy efficiency constraints and makes energy conservation and carbon reduction "rules to follow."
The relevant person in charge of the National Development and Reform Commission stated that as my country's economy has entered a stage of high-quality development, new changes in the internal and external environment, factor conditions, and supply and demand structure have put forward new requirements for energy use in key areas.
Promoting energy conservation and carbon reduction and green transformation through energy efficiency constraints, and resolutely curbing the blind development of "two highs" projects will not only help companies reduce carbon from the source, but also provide a strong guarantee for achieving the carbon peak and carbon neutral goal on schedule.
Play the leading role of energy efficiency standards
The "Opinions" clearly pointed out that by 2025, the above-mentioned key industries and data centers will achieve a benchmark level of production capacity of more than 30%, the overall energy efficiency of the industry will be significantly improved, the carbon emission intensity will be significantly reduced, and the green and low-carbon development capabilities will be significantly enhanced.
By 2030, the energy efficiency benchmark level and benchmark level of key industries will be further improved, the proportion of enterprises that have reached the benchmark level will increase significantly, and the overall energy efficiency level and carbon emission intensity of the industry will reach the international advanced level.
"Economic and social development depends on energy, but energy is limited. This requires guiding high-energy-consuming enterprises to improve technology, strengthen management, and improve energy efficiency. This is also the background for the introduction of the above-mentioned energy efficiency constraint documents." Chang Shi Xijie said in an interview with a reporter from Economic Daily.
Whether energy efficiency standards are scientific and reasonable is directly related to the effectiveness of energy conservation and carbon reduction in key industries. Therefore, continuous optimization and dynamic adjustment are required.
On the one hand, it is necessary to benchmark the advanced energy efficiency level of domestic and foreign production enterprises to determine the energy efficiency benchmark level of high-energy-consuming industries; on the other hand, it is necessary to refer to the entry value and limit value determined by the current national energy consumption limit standard per unit product, according to the actual situation of the industry , Development expectations, the overall energy efficiency level of production equipment, etc., scientifically delineate the energy efficiency benchmark level of each industry.
"The implementation of energy efficiency constraints has a basic premise, that is, it cannot affect the stable development of the economy and society, nor can it affect the stable operation of the industrial chain and supply chain." Shi Xijie said.
Deeply tap the potential of energy-saving and carbon-reducing technologies
In the industrial production process of iron and steel, chemical industry, etc., a large amount of waste heat resources are associated.
According to calculations by relevant agencies, these resources can be converted into about 600 million tons of standard coal.
"Take iron and steel as an example. The industrial waste heat resources of the whole industry are about 180 million tons of standard coal, but the current waste heat recovery rate is only about one-third." Cao Xianchang, chief engineer of Shanghai Baosteel Energy Conservation and Environmental Protection Technology Co., Ltd., told reporters that industrial waste heat resources are abundant. The potential is huge, and its recycling can not only save energy, but also has no pollutant discharge, which is a clean energy.
As the only platform for the energy-saving industry of China Baowu Iron and Steel Group, Shanghai Baosteel Energy Conservation and Environmental Protection Technology Co., Ltd. continues to carry out research on the comprehensive utilization of industrial waste heat. The level of industrial waste heat utilization has been improved and industrial energy-saving and emission-reduction technologies have progressed.
Cao Xianchang said that the industrial waste heat cascade comprehensive utilization system method and technical system have been applied and promoted in Baosteel Co., Ltd., Shaoshan Iron and Steel, Dongfang Special Steel, etc., with an annual energy saving of 324,100 tons of standard coal, creating economic benefits of 105.33 million yuan in the past three years.
In the future, every 1% increase in the industrial waste heat recovery rate can save 6 million tons of standard coal, which is equivalent to reducing 15 million tons of carbon dioxide, 67,500 tons of sulfur dioxide, and 52,125 tons of nitrogen oxides. The benefits are very considerable.
In Sinopec Corporation, the green and efficient million-ton-level ethylene package technology has made it one of the world’s five largest ethylene technology patents. Among them, special technologies such as "zero emission" startup and shutdown, refinery dry gas efficient utilization, etc. ensure that ethylene units can Leading international consumption.
Wang Beixing, a senior expert at Sinopec, said that continuing to strengthen the research and development of new energy-saving processes and new catalysts, as well as the development of new energy-saving devices and equipment, will provide stronger technical support for Sinopec's energy efficiency improvement.
While new technologies have improved the energy-saving and carbon-reduction level of industrial enterprises, they have also strongly promoted technological and equipment innovation, promoted the upgrading of technological processes and production equipment in key industries, and promoted the industry's transition to green and low-carbon.
Experts said that the "Opinions" require the full integration of scientific research institutes, associations and enterprises, the use of scientific research and innovation advantages, the development of technological equipment research, accelerating the transformation of results, stimulating the demand for green technology in the entire industry chain, and building green technology research and development and green equipment manufacturing Become the "blue ocean" of the future high-tech industry and help the high-quality development of my country's manufacturing industry.
Strengthen energy efficiency constraints scientifically and orderly
Energy conservation and carbon reduction in key areas of high-energy-consuming industries is an extremely complex systematic project and systemic change, involving the interests of governments, industries, enterprises, and the public.
At the current stage of development, relying solely on government policy directives or market self-issued actions cannot put energy conservation and carbon reduction work in place.
"In this process, the relationship between development and emission reduction, overall and partial, short-term and medium-to-long-term should be handled scientifically. On the basis of highlighting standard guidance and deepening the potential of technological transformation, it is necessary to strengthen system concepts and strengthen energy efficiency constraints in a scientific and orderly manner. "The relevant person in charge of the National Development and Reform Commission said.
According to reports, the "Opinions" scientifically defined key areas, focused on a number of key industries with relatively high energy consumption, relatively mature transformation conditions, and obvious demonstration and driving effects, and guided enterprises to carry out energy-saving and carbon-reduction technological transformations.
"For example, the steel, electrolytic aluminum, cement, plate glass, oil refining, ethylene, synthetic ammonia, etc. selected in the "Opinions" are all industries with high energy intensity per unit product and large total industrial energy consumption. The main contradiction and main aspects of the contradiction in the field of energy conservation and carbon reduction." Shi Xijie said.
To promote energy conservation and carbon reduction in key areas, it is also necessary to advance in an orderly manner and stubble on the basis of highlighting the key areas to avoid "grabbing eyebrows and beards."
Shi Xijie suggested that it is necessary to integrate existing policy toolkits, revise and improve supporting policies, and form a joint force from multiple departments and fields to jointly promote the continuous improvement of my country's energy efficiency and a significant reduction in carbon emissions.
Liu Manping, a senior economist at the Price Monitoring Center of the National Development and Reform Commission, believes that, on the one hand, it is necessary to implement the transformation, upgrading and elimination of energy conservation and carbon reduction in key industries within a time limit, and upgrade the energy efficiency transformation to above the benchmark level within the prescribed time limit, and strive to reach the benchmark level of energy efficiency. ; Eliminate the projects that cannot be completed on schedule, and limit energy consumption for projects whose energy efficiency is lower than the industry benchmark level and fail to be retrofitted and upgraded on schedule.
On the other hand, it is necessary to ensure the stable and orderly implementation of policies, and fully consider factors such as stable economic operation and the stability of the society and people's livelihood. It is necessary to advance as a whole, as well as one strategy for each enterprise.
