Recently, Jiangsu Tianhe Yuan Hydrogen Technology Co., Ltd. (hereinafter referred to as "Tianhe Yuan Hydrogen") "Tianqing" series alkaline electrolytic water hydrogen production equipment and auxiliary systems have successfully operated at Yichang Nanbo Silicon Materials Co., Ltd. and achieved excellent measured data. This is another milestone in the exploration of Tianhe Yuanhydrogen in the field of green energy, marking the commercialization and landing stage of the "Tianqing" series products, providing strong support for large-scale green hydrogen production and new energy power generation, and helping the industry move towards the era of large-scale green hydrogen production.
01 has excellent research and development capabilities, with measured data exceeding customer expectations
The hydrogen production system applied in the South Glass project was independently developed and designed by the technical team of Tianhe Hydrogen, mainly used for the process hydrogen of polycrystalline silicon devices. High purity hydrogen gas is produced by electrolysis of water, which is used to produce chlorosilane required for the production of polycrystalline silicon. After distillation and purification, high-purity trichlorosilane raw material is obtained, which is vapor deposited on the silicon core in the reduction furnace to obtain high-purity polycrystalline silicon. The entire process is quite complex, and achieving complete seamless integration and developing the entire system from scratch is bound to be a sacrifice of time and energy, which embodies the hard work and sweat of numerous Tianhe Yuanhydrogen research and development teams.

According to the energy efficiency test method for hydrogen production systems in the national standard GB32311-2015 "Energy Efficiency Limits and Grades for Water Electrolysis Hydrogen Production Systems", the DC energy consumption of Tianqing Alkaline Electrolysis Cell is 4.37kW · h/Nm ³。 Simply put, the lower the LCOH (unit hydrogen cost), the better the economy of green hydrogen, which is the core indicator for evaluating the economy of green hydrogen. The measured data of Tianqing alkaline water hydrogen production equipment also proves this point. Tianhe Yuanhydrogen's products can withstand market testing and provide customers with a better value experience.
The purity of hydrogen separated by the post-processing device is 99.86%, and the purity of oxygen reaches 99.61%. The gas purity is superior to the gas purity in the 4.1 classification of the national standard GB/T19774-2005 "Technical Requirements for Water Electrolytic Hydrogen Production System": hydrogen purity ≥ 99.7%; The requirement for oxygen purity ≥ 99.2%. The micro oxygen content of hydrogen purified by the purification device is only 1.9ppm, and the gas dew point is -70.1 ℃. These two indicators are superior to the customer's technical requirements and fully meet user needs. In addition, the entire quality system adopts closed-loop management, which eliminates deviations in a timely manner through measurement standards and monitoring measurements.
Bian Tiezheng, Deputy General Manager of Tianhe Yuanhydrogen, stated that the commercialization of this product is a valuable achievement of the entire team's exploration, and it also verifies the high compatibility between the technical direction Tianhe Yuanhydrogen has always adhered to and market demand. Tianhe Yuanhydrogen will continue to uphold the concept of "green, low energy, efficient, and reliable", continuously optimize the performance and quality of products, and improve their stability and safety. At the same time, we will continue to explore market demand, provide customers with more personalized and professional solutions, and promote the sustainable development of hydrogen energy.
02 Multidimensional Advantages Help Customers Enhance Competitiveness
The Tianqing alkaline electrolysis water hydrogen production equipment adopts an integrated bipolar plate structure design, effectively reducing the gap between the motor and the diaphragm, reducing impedance, and improving production efficiency. It is also equipped with an intelligent operation and maintenance platform with fully independent software development, data collection, analysis, and feedback capabilities. Improve the security and maintenance efficiency of the system through three-level platforms (hierarchical distribution is implemented through three-level control of the main distribution panel, cabinet, distribution box, and switch box), cloud platforms, and intelligent digital acquisition. The entire management system can achieve rapid response through functions such as rapid fault location, health diagnosis, and big data analysis, comprehensively ensuring operational safety. Zhao Gang, the project leader and chief engineer, said that the entire system is superior to similar products in terms of overall design, current density, energy consumption, and stability. High automation and smooth operation can help products achieve higher efficiency and lower energy consumption.
Of course, the successful operation of the project also relies on the cooperation of both parties. Zhao Gang said in introducing the operation of the equipment, "Over 300 days and nights, we have cooperated in a tacit manner to achieve the current results! In the testing process of the equipment, thanks to the close cooperation of Yichang South Glass, both parties have conducted detailed analysis of the challenges and difficulties in the plan in the early, middle, and later stages, and provided specific solutions, which has led to excellent results and performance." Regarding the strong alliance between Tianhe Yuanhydrogen and Yichang South Glass, Bian Tiezheng believes that the future development space is also worth looking forward to. In his view, Tianhe Hydrogen is at a leading level in the field of hydrogen energy technology. Yichang Nanbo has rich experience in the field of polycrystalline silicon, and there is still much room for future cooperation between the two sides in other hydrogen production fields.
03 Leader Level Future Promising
With the continuous intensification of global energy issues, hydrogen energy technology is considered the future of sustainable energy. The products and technologies of Tianhe Yuanhydrogen have significant commercial value, effectively reducing customer hydrogen production costs, and are an important force in promoting sustainable development. And this practice is only a microcosm of China's green hydrogen energy development. Industry insiders point out that the South Glass project not only achieves the combination of resources and industry, but also considers the hydrogen production process for polycrystalline silicon devices; More importantly, the integrated development model of new energy has been given a longer dimension of thinking, achieving long-term benefits and systematic optimization. Similar technological processes will also become an important model for the development of new energy in China in the future.
In this cooperation, Tianhe Yuanhydrogen and Yichang South Glass will leverage their collaborative advantages to open up new ideas for hydrogen production in polycrystalline silicon devices. This approach significantly reduces carbon emissions and energy consumption, thereby reducing the impact on the environment and providing reference for the further development of hydrogen energy. Not only has it brought new commercial opportunities for Tianhe Yuanhydrogen, but it also provides new ideas and directions for Yichang Nanbo hydrogen production. Open up new space for the development of the hydrogen energy market through efficient, environmentally friendly, and sustainable production methods. In the future, Tianhe Yuanhydrogen will continue to strengthen the research and implementation of hydrogen energy technology, pay attention to changes in the downstream application market and technology route of hydrogen energy, and continuously improve service quality and industry influence, create more economic and social value, and activate new green energy.
