Looking back at the decade-long development of chemical engineering technology, let’s celebrate the prosperity and strength of modern China. This is just a starting point; more participation will make the discussion more lively. HAICHUAN becomes even better with you here. [A Decade of Progress in Chemical Engineering Equipment] – A continuously updated summary thread; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhance quality awareness and promote high-quality development. ----------------------------------------- Recently, the world’s first alkaline electrolysis hydrogen production system with a capacity of 1,300 standard cubic meters per hour, developed under the leadership of China Huaneng Group Co., Ltd., began operating at full capacity at the Huaneng Pengzhou Hydrogen Production Station in Sichuan. This breakthrough marks the successful operation of an alkaline electrolyzer that is the highest in single-unit hydrogen production capacity among commercially demonstrated systems worldwide, and it holds great significance for advancing the technological development of China’s green hydrogen industry. “\"Green hydrogen\" refers to hydrogen obtained from renewable resources with no carbon emissions during its production process; it represents the future direction for the hydrogen energy industry. \"Alkaline water electrolysis for hydrogen production\" is considered the method with the greatest potential for large-scale commercial application in green hydrogen production. The electrolyzer, which is a key component of this process, plays a crucial role in advancing hydrogen production technologies and facilitating the widespread use of water electrolysis for hydrogen generation. It is understood that the core equipment of this hydrogen production system is a high-current-density pressure-type alkaline water electrolyzer with a capacity of 1,300 standard cubic meters per hour. This electrolyzer has overcome various key technical challenges, including the development of high-performance hydrogen and oxygen evolution electrodes on a large scale as well as innovations in the flow field structure of the electrode plates. It has also resolved the engineering problems associated with the assembly of large-scale electrolyzers, with many of its key performance indicators reaching international leading levels. The hydrogen production capacity of this system is 1300 Nm³/h, with a maximum of up to 1500 Nm³/h ； The rated current density is 5000 A/m², with a maximum of up to 6000 A/m² ； DC energy consumption is below 4.2 kWh/Nm³H2 ； The volume-to-capacity ratio dropped to 0.73, and all these key indicators have reached leading levels in both the international and domestic industries, providing new impetus for reducing the cost of green hydrogen. The high-performance large-scale alkaline hydrogen production water electrolyzer used in this hydrogen production system developed by China Huaneng Group is the latest achievement of Huaneng’s scientific and technological project titled “Development and Demonstration of Key Technologies for 13 MW Hydrogen Production Systems”. It was developed and constructed by Huaneng Clean Energy Technology Research Institute and Sichuan Huaneng Hydrogen Energy Technology Co., Ltd., a wholly-owned subsidiary of Huaneng Sichuan Company.

On November 8, the 1,300 standard cubic meters per hour alkaline electrolysis hydrogen production system, developed under the leadership of China Huaneng Group, began to produce hydrogen at full capacity at the hydrogen production station in Pengzhou, Sichuan. The first bottle of high-purity green hydrogen was produced, with a purity of 99.999%.
Entering the Chengdu New Materials Industry Zone, the Huadian Pengzhou Water Electrolysis Hydrogen Production Technology Innovation Demonstration Project is under active construction. According to Li Taibin, General Manager of Huaneng Hydrogen Energy, the Huaneng Pengzhou Water Electrolysis Hydrogen Production Technology Innovation Demonstration Project is the first large-scale demonstration project for green hydrogen production by the Huaneng Group, aimed at promoting the commercial application of the green hydrogen industry. As of now, the overall progress of the project is 97% complete; the civil construction work has been fully finished, and equipment installation and testing are 95% done. Completion is expected in early September, after which the project will enter the acceptance phase. Asia United Hydrogen Energy, which has signed this agreement and established its operations here, is also a leading enterprise in the hydrogen energy sector; it enjoys a high level of recognition in the industry thanks to its advanced technologies and excellent services. Through this partnership between the two parties, they will work together to push the development of Pengzhou’s green and low-carbon industries to a new level. The first phase of Huaneng Pengzhou Water Electrolysis Hydrogen Production Technology Innovation Demonstration Project involves an investment of 150 million yuan; it covers an area of about 31 mu. The construction includes a water electrolysis hydrogen production facility with a capacity of 2,600 standard cubic meters per hour (1,800 tons per year), high-density hydrogen storage equipment, and a hydrogen refueling station. Once completed, this facility will be the one with the largest single-cell capacity in the world and the first large-scale water electrolysis hydrogen production project in the southwest region. Upon reaching full operation in its first phase, the project is expected to generate annual sales revenue of 47 million yuan and annual tax revenues of 700,000 yuan. As a Huaneng Sichuan green hydrogen technology innovation and demonstration base, this project will carry out research, development, and application demonstrations related to efficient and advanced water electrolysis for hydrogen production, as well as materials, equipment, and key components for safe and high-density hydrogen storage. It aims to become a comprehensive technical demonstration project for the \"production-storage-charging\" hydrogen industry chain designed for the large-scale utilization of renewable energy. As the only demonstration project aimed at improving efficiency and reducing costs in green hydrogen production, it was included in the white paper titled \"China’s Green Hydrogen Development Roadmap.\" It plays a key role in strengthening and complementing the development of Chengdu’s hydrogen industry, providing strong support for Chengdu’s efforts to become a \"capital of green hydrogen.\"
It’s good, really great actually, hahaha
