China ha comenzado a operar su primera planta de fabricaci\u00f3n de acero con capacidad de producir 1 mill\u00f3n de toneladas, empleando hidr\u00f3geno como agente reductor y disminuyendo sensiblemente el nivel de emisiones de CO2. La planta operada por la empresa Baowu Steel, implement\u00f3 un proceso avanzado de fundici\u00f3n el\u00e9ctrica basada en hidr\u00f3geno, en reemplazo de los m\u00e9todos tradicionales (Carb\u00f3n y otros) que generan emisiones da\u00f1inas para el medio ambiente. El proyecto sirve como una aplicaci\u00f3n pr\u00e1ctica de fabricaci\u00f3n ecol\u00f3gica y de alta capacidad, permitiendo la transici\u00f3n progresiva de la industria sider\u00fargica actual de China basada en el uso intensivo del carb\u00f3n, hacia una infraestructura con menores emisiones.<\/p>\n
China has officially put into full operation its first million-tonne near-zero-carbon steel production line in Zhanjiang City, Guangdong Province. This facility, operated by Baowu Steel, reached full operational status on December 23, 2025.<\/p>\n
The project serves as a practical application of high-capacity green manufacturing, transitioning the traditionally coal-heavy steel industry toward a lower-emission infrastructure.<\/p>\n<\/div>\n
\u201cThe production line adopts an advanced hydrogen-based metallurgical electric smelting process, replacing traditional coke with hydrogen as the primary reducing agent,\u201d as reported by CGTN<\/em>.<\/p>\n By using hydrogen, the process fundamentally alters the chemical reactions in the furnace, eliminating a large portion of the carbon dioxide typically generated during the reduction of iron ore.<\/p>\n The core of the facility is a million-tonne hydrogen-based shaft furnace that produces direct reduced iron. This unit has reached its targeted metallization rates, ensuring that the raw material is of sufficient quality for high-end steel production.<\/p>\n Engineering breakthroughs and technical integration<\/strong><\/p>\n The facility integrates\u00a0high-efficiency<\/a>\u00a0green electric furnaces to process the direct reduced iron into high-grade slabs. Technical specifications from the Zhanjiang operation indicate that this line can reduce carbon emissions by 50 to 80 percent compared to conventional blast furnace methods.<\/p>\n<\/div>\n On an annual basis, the project is expected to prevent more than 3.46 million tons of carbon emissions from entering the atmosphere.<\/p>\n \u201cProject staff from Baowu Steel\u2019s Zhanjiang operation said the million-tonne near-zero-carbon steel line can cut more than 3.14 million tonnes of carbon emissions annually, equivalent to creating around 2,000 square kilometers of forest,\u201d reported CGTN.<\/p>\n Related technological developments<\/strong><\/p>\n Several related developments have surfaced in the Chinese metallurgical sector. Reports from Interesting Engineering have highlighted a \u201cflash ironmaking\u201d technique that has the potential to significantly change production speeds.<\/p>\n This method uses a vortex lance to inject iron ore powder into a high-temperature reactor, where it undergoes a near-instantaneous chemical reaction. This process is noted for being up to\u00a03,600 times faster<\/a>\u00a0than older laboratory-scale methods.<\/p>\n<\/div>\n While the Zhanjiang line focuses on large-scale hydrogen reduction, these flash techniques represent a parallel effort to improve the efficiency of iron ore processing.<\/p>\n Industrial scale and economic implications<\/strong><\/p>\n The successful operation of the Zhanjiang line comes at a critical juncture for the industry as it strives to meet the targets set under the 14th Five-Year Plan.<\/p>\n \u201cThe 14th Five-Year Plan (2021\u20132025) period is seen as a critical stage for China\u2019s steel industry to achieve high-quality development, with green transformation as a defining priority,\u201d\u00a0concluded<\/a>\u00a0CGTN<\/em>.<\/p>\n \u201cDuring this period, the number of newly certified green steel plants has increased year by year, with a total of 126 added between 2021 and 2024.\u201d<\/p>\n Beyond the direct environmental gains, the project positions China to circumvent international carbon tariffs, such as the EU\u2019s Carbon Border Adjustment Mechanism, by producing high-grade thin steel plates for the automotive and high-end manufacturing sectors with a near-zero carbon footprint.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
