On June 29, the executive meeting of the State Council deliberated and adopted the Action Plan for the Fifteenth Five-Year Plan for Carbon Peak. There is a sentence in the Action Plan that carries a lot of weight-the "15th Five-Year Plan" period is the crucial and decisive period to achieve the carbon peak before 2030. What does it mean? It's no longer "take your time", but enter the countdown. The signal released by top-level design could not be clearer: green and low carbon is accelerating its transformation from the "binding target" of the past to the "traction force" driving high-quality economic development.
For the cement industry, the pressure is real. As a major carbon emitter, in the promotion of the dual-carbon target, the cement industry is facing more than one dimension of carbon reduction challenges-the
raw material side is the biggest problem of cement carbon reduction. Carbon emissions from limestone decomposition in cement production account for more than 60%. In theory, the use of alternative raw materials such as carbide slag, steel slag and industrial waste gypsum can reduce the consumption of calcium carbonate, but the supply of these alternatives is limited, the quality is uneven, and the large-scale application is not yet mature. Energy-saving space at
the fuel end is approaching the ceiling. The comprehensive energy consumption of cement clinker in China has been significantly advanced in the world, and the standard coal consumption per ton of clinker in some new lines has been reduced to 95 kg. The space for tapping the potential of energy conservation has basically bottomed out-even if the preheater and calciner are further optimized, the emission reduction is only a few kilograms of standard coal. Alternative fuels are the way out, but the current substitution rate is still low, and the full substitution of clean fuels still needs to be promoted for a long time.
The power side is relatively optimistic. With the popularization of clean energy such as wind and solar power and the continuous decline of power grid emission factors, the downward trend of power carbon emissions in cement enterprises is clear. The landing of photovoltaic, energy storage, virtual power plants and other technologies provides enterprises with a realistic path of electricity price arbitrage and carbon reduction. There is still room for
transport links. Although the proportion in the whole life cycle of cement is not high, the green transformation of transport structure, such as "public transit railway" and increasing the proportion of water transport, will release considerable emission reduction in the medium and long term.
These problems are not on paper, but the accounts that every production line and every ton of clinker have to face. Where is the way out?
From July 29 to 30, the 15th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 7th Intelligent Summit Forum , sponsored by China Cement Network and co-sponsored by Conch Group, will be held in Wuhu, Anhui Province. The theme of the conference is " Double Carbon Leads Energy Conservation and Cost Reduction ", and the topics almost accurately cover the four major problems mentioned above-the diversified application of alternative fuels, the latest progress of low-carbon clinker and cementitious materials, the application of alternative raw materials for industrial waste residues, the landing scheme of photovoltaic energy storage and virtual power plants.. Each item points directly to the real "hard bone" of carbon reduction in the industry.
It is worth mentioning that during this meeting, we will organize a visit to the first AI model and digital exhibition hall of the cement industry released by Conch Group, which will provide a touchable reference for the intelligent transformation of the industry.
When the carbon peak enters the decisive period, the choice of technology path is more critical than ever before. It is better to sit down and talk than to grope for each other. See you in Wuhu.
