The first production line of GCL Technology’s 100,000-ton per year granular silicon project in Leshan, Sichuan, has been officially put into operation

The 100,000-ton granular silicon project at the Leshan facility is GCL Technology’s first granular silicon plant built in the western region, and it also represents a green, ecological, and intelligent factory of GCL. The project is located in Leshan City, Sichuan Province, an area rich in hydroelectric resources. It enjoys a unique advantage in terms of green energy, and will help build Leshan into a \"Green Silicon Valley of China\". It will also provide strong support for achieving the **\"dual carbon\" goals and advancing the development of a \"carbon economy\". The successful operation of this project indicates that GCL-FBR’s capability for modular replication of granular silicon production has reached a level of 100,000 tons, laying a solid foundation for the company to advance into higher levels of modular replication in the future. At the GCL project site in Leshan, reporters saw rows of silane reaction towers standing tall, shining with a metallic luster under the sunlight. Fluidized bed reactors were operating continuously, and silicon products in the form of grain-sized particles were being produced in an endless stream. In the vast central data center, the staff members all watch the large screens, carefully and systematically monitoring, analyzing, and managing each process as well as the real-time data. A responsible official from GCL Technology stated that at present, the Leshan GCL granular silicon project is in a stable operating state, with various parameters such as product quality, production efficiency, process technology, and cost control having reached or even exceeded the predetermined targets. Once the project reaches full production capacity, it will help alleviate the strong demand in the market for GCL-FBR granular silicon, further highlight its technological advantages, and solidify its leading position in the photovoltaic raw materials market. At the same time, GCL Technology will place greater emphasis on using granular silicon, a low-carbon and high-tech silicon-based material, as a foundation to develop a photovoltaic industry chain that is low in carbon emissions or even carbon-neutral. This approach will help accelerate the decarbonization of the new energy sector. Against the backdrop of achieving carbon peak and carbon neutrality, it will also promote innovation and upgrading within the global clean energy industry, as well as drive technological revolutions. “The Leshan GCL granular silicon project has been successfully put into operation, and it will serve as a groundbreaking new milestone that will reshape the landscape of raw material supply in the global photovoltaic industry. ” A senior industry analyst told reporters, “In the past, rod-shaped silicon has dominated the market, while granular silicon has seen limited production due to high technical barriers and great difficulties in overcoming them, preventing it from being widely adopted on a large scale quickly.” ”However, relying on its years of hard work and expertise, GCL Technology brought with it the technology, experience, and team accumulated over more than a decade from its Xuzhou base, which is the hub for granular silicon production. It then headed to Leshan in Sichuan, a key city in the southwest and a fertile ground for green silicon industry, where it raised the production capacity of granular silicon from tens of thousands of tons to hundreds of thousands of tons, setting new global records in the photovoltaic industry twice within one year. “Next, as new production capacities of hundreds of thousands of tons of granular silicon are brought online at GCL Technology’s facilities in Baotou, Hohhot and other locations, the supply-demand imbalance caused by a shortage of granular silicon will be significantly alleviated. The dual benefits associated with granular silicon – low costs and high efficiency, along with a favorable carbon footprint – will lead to exponential growth in its advantages. ”The analyst added, “As pioneers of the 3060 ‘carbon’ pathway, an era led by GCL’s granular silicon has arrived.” ”

The successful commissioning of GCL Technology’s 100,000-ton per year granular silicon production facility in Leshan has also attracted widespread attention within the industry. Industry experts told reporters that, against the backdrop of global energy shortages and the high carbon emissions associated with fossil fuels, GCL’s granular silicon – which features low costs, high efficiency, and a low carbon footprint – has become a groundbreaking silicon-based energy product made in China that can have an impact on the world. 2022 will also mark the beginning of large-scale production of GCL’s granular silicon, providing essential technological support and a solid foundation for accelerating green and efficient research, development, and manufacturing within the photovoltaic industry, as well as for speeding up the low-carbon and zero-carbon transition in the global energy sector. As a **patent**, GCL-FBR granular silicon technology is an advanced innovation that GCL-Power has spent over 10 years developing. Compared to the rod-shaped silicon produced using the company’s traditional processes, GCL-FBR granular silicon offers distinct advantages in terms of cost, carbon emissions, and product quality. In October 2021, after obtaining the first carbon footprint certification for granular silicon from a reputable Chinese authority, GCL Technology also received the world’s first such certification issued by the French Environment and Energy Management Agency. This certification showed that the carbon footprint per kilogram of granular silicon produced was only 37.000 kilograms of carbon dioxide equivalent, **breaking the previous global record held by German company Wacker, which was 57.559 kilograms of carbon dioxide equivalent. It is reported that, compared to rod-shaped silicon produced using traditional methods, the production of 10,000 tons of granular silicon can result in a reduction of 389,000 tons in carbon dioxide emissions. According to research conducted by the Swiss Federal Institute of Technology in Zurich, 1 hectare of tree canopy can absorb 205 tons of carbon dioxide per year; in other words, for every 10,000 tons of granular silicon produced, it is equivalent to planting an additional 1.9 million trees per year. Based on GCL Technology’s particle silicon production capacity of 260,000 tons in 2022, this would result in a reduction of 10.114 million tons of carbon dioxide emissions per year, which is equivalent to planting 49.4 million more trees. Once GCL Technology’s planned production capacity of 600,000 tons of particle silicon is fully operational, it will mean an additional 114 million trees can be planted each year.

The industry generally believes that GCL-FBR granular silicon from GCL-Power, as a next-generation silicon-based material, will reshape the innovation and technological landscape of the photovoltaic industry thanks to its various key advantages such as low cost and high efficiency, as well as an excellent carbon footprint. It will have a profound impact on the future development of the photovoltaic industry and the clean energy revolution. “The European Parliament has approved the EU carbon tariff scheme; low-carbon products will command higher premiums. In the future, GCL’s silicon granules with a low carbon footprint will provide strong support for Chinese photovoltaic products to reach global markets. ”The aforementioned analyst said. Since GCL Technology entered the photovoltaic sector in 2006 by developing its own improved Siemens process, thereby breaking the foreign technological monopoly and rapidly growing into a world-leading polysilicon company, to today’s stage where GCL-FBR particle silicon technology is being produced on a scale of 100,000 tons, over these 16 years GCL has consistently strived to advance photovoltaic technology and actively participated in the global energy transition. It has set a \"GCL example\" for China and the world as a whole in helping to move photovoltaic power generation from an era of high costs to one with lower prices, and from high carbon emissions to low carbon emissions. A relevant official from GCL Technology said, “In the era of traditional energy, we imported fossil fuels from abroad. But as we enter the era of new energy, GCL will focus on the next generation of ‘silicon-based energy’ – granular silicon – to provide the world with a continuous supply of ‘green oil’.” In the future, GCL will work together with the entire industry to make active contributions to achieving the ‘dual carbon’ goals at an early date. ”

The new 30,000-ton project in Xuzhou began construction on October 26, 2021, and it was able to go into operation just 8 months later. Together with the 30,000-ton project at the Xuzhou facility that has already been fully operational, the production capacity of FBR granular silicon has officially entered the \"6.0 era\". With the successive commissioning of a series of granular silicon projects in regions such as Jiangsu, Sichuan, and Inner Mongolia, the strong demand for polysilicon in the market will be significantly alleviated. This will further strengthen the position of FBR granular silicon in the photovoltaic materials market, having a profound impact on the global photovoltaic industry landscape. The 30,000-ton per year production capacity of FBR granular silicon at GCL Technology’s Xuzhou facility has already met the requirements for N-type silicon wafers; this quality is continuing to improve. The overall electricity consumption is 14.8 kWh/kg, while the overall steam consumption is 15.3 kg/kg. In October 2021, after obtaining China’s first carbon footprint certification for granular silicon, GCL Technology also received the first such certification issued by the French Environment and Energy Management Agency. This certification indicated that the carbon footprint per kilogram of granular silicon produced was 37.000 kilograms of carbon dioxide equivalent, **breaking the previous global record set by German company Wacker, which was 57.559 kilograms of carbon dioxide equivalent under high-hydropower conditions.
