On August 22–23, the Uhai Science and Technology Bureau organized a meeting to advance the project related to the autonomous region’s major science and technology initiative, namely the development of key pressure-feeding equipment for 70MPa hydrogen stations. Li Jiangbo, deputy director of the Uhai Science and Technology Bureau, attended the meeting and delivered a speech. Renowned experts and scholars from Uhai Dongyuan Technology Co., Ltd., Tsinghua University, Xi’an Jiaotong University, Jiangsu Guofu Hydrogen Energy Technology Equipment Co., Ltd., Fengdian Jinkewei (Suzhou) Compressor Co., Ltd., Inner Mongolia University, Inner Mongolia Dongyuan Polymer Materials Science Research Institute, China Global Engineering Co., Ltd., Jiangyin Furun High-Tech Co., Ltd., and Zhejiang Zhehua Investment Co., Ltd. participated in the meeting on site. As refueling stations for fuel cell vehicles, hydrogen refueling stations are important infrastructure for hydrogen energy, and they represent a key area of research for the utilization of hydrogen in the transportation sector. “The project on \"Key Equipment for Pressurized Refueling in 70MPa Hydrogen Stations\" is led by Wuhai Dongyuan Technology Co., Ltd., with the participation of 9 universities, research institutions, and high-tech enterprises. Through the active efforts of the Wuhai Science and Technology Bureau in making recommendations to higher authorities, the project received support in the form of a major science and technology initiative funded by the Inner Mongolia Autonomous Region. The total funding for the project amounts to 47.81 million yuan, of which 22.81 million yuan comes from government grants. To date, the project is progressing smoothly, with significant interim results already achieved. The project team has successfully developed China’s first diaphragm compressor for 90MPa hydrogen refueling stations, filling a gap in the country’s infrastructure and achieving domestic substitution for diaphragm compressors as well as a technological breakthrough in high-pressure diaphragm compressors. The product exhaust pressure is ≥87.5 MPa, the exhaust flow rate is ≥200 Nm3/h, and the equivalent shaft power is ≤42 kW ； Continuous fault-free operation for ≥500 hours (50 start/stop cycles). Core components such as air valves, oil overflow valves, and diaphragms all have a continuous fault-free operation time of ≥1000 hours. The various performance indicators of this product are at an advanced level both domestically and internationally; therefore, it is possible to further promote the use of this model in the hydrogen energy sector. This will help meet the growing demand for hydrogen energy infrastructure in China, accelerate the development of hydrogen energy initiatives in the country, and provide a wider range of product options for the advancement of hydrogen energy technologies.
