Recently, the Qilu liquid hydrogen project, for which Guofu Hydrogen provides core equipment sets and engineering technical services, achieved scaled production of 10 tons of liquid hydrogen per day. This is China’s first hydrogen liquefaction plant with a capacity of 10 tons per day and fully domestic independent intellectual property rights. It is reported that the Qilu liquid hydrogen project is located in Zibo City, Shandong Province, with a total investment of 550 million yuan. It will be constructed in two phases: Phase 1 will have an annual production capacity of 3,300 tons of liquid hydrogen, while Phase 2 will enable an annual production capacity of 9,900 tons once it is operational. The mass production of this project features four key highlights: 1. Clear development timeline: The core equipment for the project was completed in May 2023 ； In May 2024, the installation of core equipment and comprehensive testing were completed in Zibo, Shandong, and the system passed evaluation by authoritative experts ； After multiple rounds of optimization tests, it is now ready for mass production. 2. Excellent product specifications: The comprehensive energy consumption of the mass-produced liquid hydrogen is below 12 kW·h/kg – LH2, with a purity of over 7N and a secondary hydrogen content of more than 98.5%, reaching international advanced levels; it can meet the requirements of various applications such as fuel cell-based transportation and semiconductor-grade gases. 3. Technical independence and control: It adopts a multi-stage pre-cooling hydrogen expansion refrigeration technology developed independently; core components such as the 20K hydrogen liquefaction cryocooler and hydrogen expansion machine are all covered by independent intellectual property rights. The equipment also features a compact structure, high heat exchange efficiency, and stable operation. 4. Significant industrial value: It lays the foundation for subsequent hundred-ton-scale liquid hydrogen projects. As an important technical approach for the strategy of transporting hydrogen from the west to the east, it enables the large-scale use of long-distance water and land transportation for liquid hydrogen, and also provides a viable solution for peak-shaving and energy storage in hydrogen transmission pipelines.
