The Birth of 'Tianqing'

Date:2023.06.16

Hydrogen production is not a new thing. In the last century, people had learned to use fossil fuels to produce hydrogen, and later this method of hydrogen production, which generates a large amount of greenhouse gases, was called "gray hydrogen". However, with the increasing emphasis on carbon emissions, green hydrogen produced from new energy sources has begun to enter people's vision. This technology of hydrogen production through electrolysis of water, which has never been scaled up, shows greater appeal. At the same time, the domestic hydrogen production equipment industry has ushered in a strong counterattack momentum, leading the arrival of a new era of green energy.

Jiangsu Tianhe Yuan Hydrogen Technology Co., Ltd. (hereinafter referred to as "Tianhe Yuan Hydrogen"), a domestic clean energy technology enterprise, has achieved remarkable results in achieving green energy transformation through continuous innovation and manufacturing the first alkaline electrolytic water hydrogen production equipment "Tianqing" series. It has been successfully applied in the Yichang South Glass Project, bringing new opportunities for the upgrading and development of the domestic clean energy industry.

Part 1

Throughout the past, the long-standing monopoly of overseas enterprises in the hydrogen production equipment market has brought huge challenges to domestic enterprises. Factors such as technological barriers, patent control, and production scale advantages have placed domestic enterprises at a disadvantage in the field of hydrogen production equipment. This monopolistic situation not only limits the development of the domestic green energy industry, but also poses huge challenges for China in terms of energy autonomy and controllability.

According to statistics, in the past two years, national ministries and commissions have issued over 50 policies related to hydrogen energy, and local governments have issued over 300 policies related to hydrogen energy. It can be predicted that with the continuous expansion of the impact of the medium and long-term development plan of hydrogen energy and the implementation of policies at all levels, the hydrogen energy industry will take advantage of the situation and be around the corner.

However, for the development and utilization of hydrogen energy, China is still at a preliminary and developing level, with many key technical issues still unresolved. The localization of core technical equipment has become the "Achilles' heel" of hydrogen energy. Compared with developed countries, there is still a certain gap in China's independent research and development of hydrogen energy technology, equipment manufacturing, and infrastructure construction.

From an industry perspective, the hydrogen energy industry is similar to wind power photovoltaic, pure electric vehicles, and even the communication industry. It can fully rely on China's strong industrial foundation, achieve economies of scale through continuous independent innovation and market applications, form global competitiveness, and ultimately achieve industrial latecomers. At present, technological innovation is also needed to improve product performance and achieve more efficient and cost-effective technological applications.

The White Paper on China's Hydrogen Energy and Fuel Cell Industry points out that by 2050, the proportion of hydrogen energy in China's energy system will be about 10%, and the demand for hydrogen will be close to 60 million tons, with an annual economic output value exceeding 10 trillion yuan; More than 10000 hydrogen refueling stations will be established nationwide, and hydrogen energy will be widely used in transportation, industry, and other fields. In recent years, domestic enterprises have gradually achieved a comeback in domestic hydrogen production equipment through unremitting efforts and innovation.

Tianqing was born against this background.

In 2021, Tianhe Yuanhydrogen was established. This young enterprise has successfully developed the "Tianqing" series of alkaline water hydrogen production equipment with efficient energy conversion and reliable stability by continuously promoting innovation. And successfully put the first set into offline operation in 2022. The "Tianqing" series, with its outstanding performance characteristics, has achieved efficient production of green hydrogen gas and can provide reliable support for achieving new energy power generation; Its advanced design and process flow make it excellent in energy utilization efficiency and sustainability, bringing new changes to the domestic energy industry and injecting strong impetus into the development of the green energy industry.

Of course, behind this breakthrough innovation, tremendous efforts and research and development difficulties have been put in place. After years of continuous research and experimentation, the Tianhe Yuan Hydrogen team has overcome technical difficulties and continuously optimized and improved equipment performance. After continuous trial and error and iteration, the "Tianqing" was finally successfully launched.

The most crucial thing is the rigor in the entire production and manufacturing process of the equipment, "emphasized Liu Wanming, Chief Engineer of Tianhe Hydrogen, In the process of equipment manufacturing, whether it is a small screw or a small burr on the electrode plate, we pay high attention to it. For example, in our battery assembly, when we assembled more than 200 pieces, we found a question and immediately disassembled and reassembled all these 200 pieces to ensure the absolute reliability of the equipment. In his opinion, hydrogen production equipment must not have a rough, should, or similar appearance.

Last year, during the entire production process of the equipment, our chief engineers stayed in the workshop throughout the entire process. There was no air conditioning in the workshop, and when it was hot, it was so hot that we wished to scorch the ground. When it was cold, we couldn't even see our glasses when we breathed in. But this was just a small idea, and we were used to it. Without it, we couldn't rest assured. It was precisely because of the full control of the equipment production process that we could ensure the stability and technology of the equipment in all aspects The outstanding performance of the technique ultimately achieved today's results

Liu Wanming stated that the main parameter we are concerned about is the purity of hydrogen gas. Compared with the commonly used diaphragm technology in the industry, we have adopted PPS (polyphenylene sulfide) technology. After separation by a post-treatment device, the hydrogen purity obtained is 99.86%, and the oxygen purity reaches 99.61%. This result is superior to the gas purity in category 4.1 of the national standard GB/T19774-2005 "Technical Requirements for Water Electrolytic Hydrogen Production System".

According to Liu Wanming, the main problem faced by large-scale hydrogen production equipment is that it cannot meet the requirements for long-term operation. The client requirement of Tianhe Yuanhydrogen is to operate 24 hours without downtime, which puts high demands on the stability of the equipment. According to factory control requirements, the products of Tianhe Yuanhydrogen will be tested in the factory before shipment. After more than a month of long-term operation and testing, the energy consumption and overall performance of Tianqing have been stable, which is actually not easy.

In addition to design level optimization, safety is also the bottom line of the energy industry. Regardless of the type of equipment, especially those with certain risks such as our hydrogen production equipment, safety is the primary consideration for clients. Regardless of the industry, safety production must be put first. The key to a company's normal operation is whether its safety performance is reliable, because a safety accident may bring huge losses to the company. "Liu Wanming emphasized, During the debugging and operation of equipment at China Southern Glass Corporation, we conducted comprehensive tests on all alarm points, interlocking points, and automatic controls, and received positive recognition from customers

Liu Wanming mentioned, "The equipment adopts a fully automated PLC control system. When programming, we will test each alarm point and interlock point, and record each test result. During operation, when we find a problem with engine selection, the system will automatically handle it. It can be said that our equipment has made significant improvements in safety and stability

No matter how difficult the process may be, it is considered a normal thing, which means there is nothing worth saying for us, "Liu Wanming said. This is just a routine matter within our scope of responsibility. We believe that these things are what we should do, and everything is very ordinary

The birth of 'Tianqing' is the perseverance of a group of people and the crystallization of everyone's unremitting dedication. They are well aware that only through teamwork and hard work can such outstanding results be achieved. They believe that only by continuously pursuing excellence can we continuously promote technological progress and contribute to the development of the industry. We will continue to extend this perseverance and effort, explore new possibilities for future hydrogen energy development, and contribute to building a better world.

In the industry's view, the collaboration between Tianhe Yuanhydrogen and Yichang South Glass is a two-way journey under the background of "dual carbon". This cannot be separated from Yichang South Glass's high awareness of green energy and the design concept of Trina Solar Hydrogen.

With the increasing global demand for green energy, various industries are actively seeking ways to achieve sustainable development. In this wave of green transformation, Yichang South Glass Group deeply recognizes the urgency and importance of turning to green energy, and needs to achieve green energy transformation, reduce carbon emissions, and improve energy utilization efficiency through reliable and efficient solutions.

In order to meet the needs of Yichang South Glass Silicon Materials, the "Tianqing" series starts from the technical level, manufacturing process, efficiency, and other aspects, promoting the cost reduction of electrolytic water hydrogen production, and becoming the ideal choice for Yichang South Glass.

Compared with traditional alkaline electrolyzers, the Tianqing series has higher electrolysis efficiency and lower energy consumption, which can achieve savings in asset investment. In the hydrogen energy market, LCOH (unit hydrogen cost) is the core indicator for evaluating the economic viability of green hydrogen. According to the calculation, every 0.1kWh/Nm decrease ³ The DC power consumption of hydrogen production can indirectly reduce LCOH by 1.8% -2.2%, thereby reducing the initial investment of hydrogen production equipment by 10% -25%. The DC power consumption of the Tianqing series can be reduced to 4.3kWh/Nm under full load conditions ³, Expected to reach 3.9kWh/Nm in the future ³, Achieving optimal LCOH in different application scenarios is of great significance for reducing the cost of hydrogen production.

In other aspects, "Tianqing" has also performed well. From the perspective of current density, its overall operating current density can be increased by about 50% -75%, reducing DC power consumption by 10% -15%. Moreover, it is important to note that compared to products with the same output energy consumption, Tianqing can reduce its volume by 30% through reasonable pipeline layout design, making the application scenarios more flexible and extensive. The purity of the gas also fully meets the customer's requirements for polycrystalline silicon reduction. 1000 Nm was used in this South Glass project ³/ H is a standard product, but can be customized according to customer needs, with a maximum hydrogen production capacity of up to 2000Nm per tank ³/ H.

The demand for energy in the entire market and the requirements of customers are very important now. Therefore, in the manufacturing process, we pay great attention to the issue of energy consumption. Whether it is the selection of materials or the design of internal components, we pay attention to every detail to ensure the effective utilization of energy. Taking the equipment in the South China Glass project as an example, our design meets conventional standards, but the energy consumption of the actually manufactured equipment in the industry is the most significant Low Liu Wanming said so.

The Tianqing series features easy maintenance and intelligent control, and adopts an integrated pry mounted design to achieve independent control, ensuring the safety and reliability of the entire system. In the face of harsh environments, Tianhe Hydrogen can provide customized mobile hydrogen production stations with convenient installation and excellent maneuverability, which can facilitate fast transportation and effectively solve the economic and safety issues of "fuel hydrogen" and hydrogen storage and transportation. Achieving self-sufficiency in hydrogen production within the station, as well as eliminating the need for long-distance trailer transportation and loading and unloading processes, resulting in no transportation costs, can reduce the cost of terminal hydrogen consumption.

Part 4

The successful case of cooperation between Yichang South Glass Silicon Materials and Tianhe Hydrogen is a vivid example of the counterattack of domestic hydrogen production equipment. By introducing the Tianqing series, Yichang South Glass Silicon Materials has achieved a transformation of traditional energy and set an example for other similar industries. With the urgent need for green energy transformation, more and more enterprises are paying attention to the utilization of renewable energy and the application of green technologies.

The breakthrough innovation of Tianhe Yuanhydrogen's "Tianqing" series hydrogen production equipment not only provides reliable solutions for the domestic energy industry, but also demonstrates the strength and competitiveness of China's hydrogen production technology on the international stage.

Since the establishment of the "Tianqing" series project, it has not only witnessed the leapfrog transformation of equipment from research and development to the first commercial implementation. More importantly, it has led the breakthrough and development of the domestic hydrogen production equipment industry. This is not only a successful achievement of the equipment, but also a milestone in the practical application and promotion of domestic clean energy technology.

The breakthrough of the domestically produced "Tianqing" series alkaline electrolytic water hydrogen production equipment not only solves the overseas monopoly problem faced by the domestic energy industry, but also promotes the upgrading and development of the domestic clean energy industry. Through independent innovation and technological breakthroughs, domestic hydrogen production equipment has become an important choice for domestic enterprises to achieve green energy transformation.

As the demand for green energy continues to grow, the pace of technological innovation in Tianhe Hydrogen will not stop.

For the development of an enterprise, the first thing to rely on is the foundation of technology, and then it also depends on the company's investment. Both of these are indispensable. Without technology, even a large investment is useless; but with technology, if the company does not invest, it cannot develop. These two are complementary relationships. "Liu Wanming said that in terms of technology, Tianhe Hydrogen is currently striving to lead in China, but is not satisfied with stagnation.

We are still conducting research and development and seeking new breakthroughs. We also need to further improve our equipment and promote technological development. Our current focus is to alleviate operational pain points, while actively seeking new materials. We hope to achieve synchronous development of technology and equipment. According to Liu Wanming, Tianhe Hydrogen is also exploring opportunities for seawater hydrogen production technology, as long as it can bring breakthroughs to the market, The technical team will definitely go all out without reservation!

The green hydrogen produced in the past only needed to meet a small number of high-precision and cutting-edge industries such as semiconductors, pharmaceuticals, and aerospace, but now China's positioning of hydrogen is as an "energy". Energy means achieving low-cost, large-scale, reliable, and safe localization.

Liu Wanming believes that for Chinese enterprises, many are still accustomed to a more extensive management approach. If this extensive approach is continued, it will cause some controversy and shortcomings. In this regard, China's hydrogen energy equipment manufacturing needs to be more meticulous.

R&D takes time and cannot be achieved overnight, so we need a certain amount of time to meet the requirements. I think it takes a certain amount of time to polish and produce high-quality products. "Liu Wanming sighed," In terms of hydrogen energy technology, we will definitely not stop or take steps in the same place. We need to continue to move forward because the hydrogen energy industry has some special characteristics

At present, the hydrogen energy industry has achieved rapid cost reduction in the process of domestic substitution, and further equipment costs need to be reduced through technological and engineering innovation in the future; In addition, with the decrease in the cost of new energy generation and the reduction in the price of production, storage, transportation, and equipment, the price of hydrogen will also decrease. It is not far from clean and cheap hydrogen.

Industry experts predict that as the hydrogen energy technology innovation system gradually improves and technological breakthroughs are continuously achieved in fields such as hydrogen production, hydrogen storage, and fuel cells, the cost of hydrogen application will further decrease, and it is expected to enter the market on a large scale in the future. Domestic giants such as Tianhe Yuanhydrogen have entered the market, seizing opportunities for the development of the hydrogen energy industry, and helping China's energy transformation and green development. This will definitely enable us to see a greener and cleaner energy future!
