The double scene was selected as the first batch in Hunan! Sany Hydrogen Energy's "Green Hydrogen" project leads the low-carbon transformation of industry

Recently, the Hunan Provincial Department of Industry and Information Technology announced the list of the first batch of low-carbon hydrogen application scenarios in the industrial field. The two benchmark projects of Sany Hydrogen Energy Co., Ltd., the "Demonstration Project for the Application of Hydrogen-based Low-carbon Metallurgy and Protection Technology" (jointly implemented with Hunan Lianyuan Steel) and the "Green Power Hydrogen Production and Hydrogen Refueling Integrated Station and Hydrogen Transportation Demonstration Project", were successfully selected.

This marks that Sany Hydrogen Energy has made a substantial breakthrough in promoting the large-scale industrial application of green hydrogen and helping the deep decarbonization of high-carbon industries, and has been recognized by provincial authorities.

Metallurgical "hydrogen instead of carbon" to create a new paradigm of green steel

The 250 standard/hour alkaline water electrolysis hydrogen production system jointly built by Sany Hydrogen Energy and Hunan Lianyuan Steel has an annual output of 2 million cubic meters of green hydrogen, achieving a breakthrough in the process of "replacing carbon with hydrogen" in the iron and steel industry. The project innovatively applies the third-generation hydrogen production technology (DC power consumption≤ 4.3kWh/Nm³) and is equipped with an intelligent control system to use green hydrogen on a large scale in two core links:

(1) Galvanized protective gas: replace nitrogen-hydrogen mixture to improve the adhesion of zinc layer;

(2) Steelmaking reducing gas: 20% of the proportion replaces coke oven gas, and carbon reduction of 0.8 tons per ton of steel.

The system has been running stably for 1,500 hours, with an equipment availability rate of 99.3% and an annual carbon dioxide reduction of 12,000 tons. At present, it has been applied in the cold-rolled high-end household board construction project of Hunan Valin Lianyuan Iron and Steel Co., Ltd., providing a replicable and promotable demonstration path for green metallurgy.

Transportation "production, storage and use" to solve the bottleneck of hydrogen economy

Sany Hydrogen Energy leads the construction and operation of a 2,000-kilogram hydrogen production and refueling station, adopts the water electrolysis hydrogen production technology of photovoltaic green electricity coupled with valley electricity, and supports a 1060kg hydrogen storage system to achieve 24-hour stable hydrogen supply. The project innovatively applies 2000 standard cubic meters/hour electrolyzer (the first engineering application in China), large-displacement compressor and intelligent control technology in the station, reducing the cost of hydrogen production to less than 28 yuan/kg.

The demonstration scenario covers hydrogen energy muck trucks, heavy trucks, logistics vehicles and other transportation fields, with a total of more than one year of trial operation, more than 40 tons of low-carbon hydrogen, and more than 400 service vehicles, fully verifying the "production-storage-processing-use" hydrogen closed-loop model. Promote through the collaborative demonstration of "car-station-slot".Hydrogen equipmentIndustrialization.

Under the guidance of Sany Group's low-carbon strategy, Sany Hydrogen Energy firmly implements the strategy of "quality first", adheres to the development concept of "no volume, no volume, volume quality", comprehensively promotes the layout of "3+1" product matrix (circular tank, square tank, PEM tank, BOP system), further expands multiple application scenarios such as hydrogen chemical industry, hydrogen metallurgy, hydrogen transportation, and natural gas hydrogen blending, and accelerates the high-end, engineering, and industrialization of hydrogen production equipment. Contribute to the high-quality development of the industry with "Sany Power" and "Sany Plan".
