CPPE – Launch of 100,000-Household Demonstration Project

On April 19, China’s first large-scale demonstration project for hydrogen-blended natural gas, serving up to 100,000 households, was launched in Weifang, in east China’s Shandong Province, with technical support from the China Petroleum Pipeline Engineering Corporation (CPPE), a subsidiary of China Petroleum Pipeline Engineering Co., Ltd. (CPP).

Focusing on hydrogen applications in pipeline systems, CPPE, together with partners, advanced key technologies for integrating hydrogen into urban gas infrastructure. The company established an integrated hydrogen microgrid testing platform covering production, storage, transportation, blending, and end use. Using this platform, CPPE verified the safety and reliability of pipeline materials, valves, metering systems, and sealing materials under different hydrogen blending ratios. These efforts supported the safe and efficient use of hydrogen in pipeline-based urban gas networks and enabled residential applications. CPPE also led the development of China’s first design standard for hydrogen pipelines, established evaluation methods and a performance database for hydrogen transmission materials, and developed a real-flow hydrogen metering platform. In addition, it designed a dedicated hydrogen pipeline compliant with urban gas standards, with an annual capacity of 30,000 tonnes.
