【Ten Years of Rapid Development in Chemical Engineering Equipment】2826–2025: Verification of the First Domestic Megawatt-Class Pure Hydrogen Gas Turbine Operating at Full Load for 72+24 Hours Continuously

Thread Content

Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Progress in Chemical Engineering Equipment】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On November 8th, China’s first megawatt-class pure hydrogen fuel cell engine (with a rated power of 1.7 megawatts and model BGT-H017), developed independently by **Dian Tou Group Beijing Chongran Energy Technology Development Co., Ltd. (hereinafter referred to as ‘Beijing Chongran’), successfully passed the 72+24 hour full-load continuous operation test. During operation, all performance indicators of the unit met the expected standards; NOx emissions ranged from 7 to 20 ppm at 15% O2, and its overall performance was at an internationally advanced level. This is also the first domestic pure hydrogen combustion engine that has been independently developed and gone through a complete product validation process, marking an important breakthrough for China in the field of hydrogen combustion engines. ▲Actual photos of the first domestic megawatt-class pure hydrogen gas turbine test platform, developed under the leadership of Beijing Chongran. Since the unit completed its full-load test in June 2024 and passed the performance acceptance test for the entire unit in September of the same year, Beijing Heavy Reburning has continued to work on finalizing the product and enabling its practical application. With the support of partners such as the Energy Research Institute of China Power Investment Group and Hubei Company, the project team has carried out multiple rounds of product upgrades and verification efforts, laying a solid foundation for the successful 96-hour continuous full-load operation. The successful long-duration operation of the BGT-H017 pure hydrogen combustion engine not only verifies that this type of engine is ready for market deployment and large-scale use, but also demonstrates the sophistication and reliability of the key core technologies integrated into it, such as the DLN (dry low-nitrogen oxides) micro-premixed combustion technology, operation control technology, and safety monitoring systems. These key technologies developed by Beijing Chongran possess complete independent intellectual property rights. They not only feature unique technical continuity but also exhibit excellent adaptability across a wide range of applications, allowing them to be used in micro gas turbines of 100 kilowatt class to gas turbines of 100 megawatt class. This facilitates the development of a series of hydrogen fuel turbine products within a relatively short research and development cycle. In addition, various important achievements developed by Beijing Chongren, such as the low-NOx pure hydrogen burner, hydrogen flame detection system, and combustion visualization system, are all domestically pioneering. They can be directly applied to the low-carbon and low-nitrogen transformation of existing power units, possessing significant value in terms of technology transfer and broad market application prospects. Driven by the \"dual carbon\" goals and the rapid development of new energy sources, hydrogen is emerging as an important energy pillar for China to achieve its carbon neutrality targets. Hydrogen fuel cells combine functions such as energy storage, peak shaving, frequency regulation, and phase regulation, which further enhances their overall value in new power systems; they will play an important role in contributing to various clean energy applications. The successful development of megawatt-class pure hydrogen engines in Beijing is not only an important achievement of **Power Investment’s proactive approach to the hydrogen energy industry, but it also represents a successful exploration of a technology development path for hydrogen engines that suits China’s national conditions. It will provide strong support for promoting the green transition of energy, building a new type of power system, and implementing **Power Investment Group’s ‘balanced growth strategy’.
