According to Sinochem New Network, on December 10, news came from **Pipeline Group stating that China’s first full-scale venting test of a high-pressure hydrogen pipeline at 10 megapascals was successfully carried out. This test served as a kind of \"safety simulation test\" for hydrogen pipelines, filling a technical gap in this field in China and marking a new advancement in the country’s technology related to hydrogen pipeline safety. To achieve widespread use of hydrogen energy, it is essential to ensure the safety and stability of long-distance hydrogen transportation. During pipeline operation, planned maintenance may be required at times, or emergencies can occur; in such cases, it is necessary to release the hydrogen inside the pipeline quickly and safely—this process is known as \"venting\". How to ensure that high-pressure hydrogen does not pose any danger or cause any impact on the outside environment during venting is precisely the core issue to be addressed by this venting test. This experiment established a complete simulation testing platform that accurately replicated the various scenarios in which hydrogen needs to be released during the actual operation of pipelines, including safe release without ignition and release during ignited combustion, while also testing the safety performance under different pressure and operating conditions. The research findings will be directly applied to the construction of future large-diameter hydrogen pipelines, thereby improving the safety level of pipeline operation. **Yu Bin, director of the New Energy Engineering Technology Center at the Pipeline Network Group’s Engineering Technology Innovation Company, explained that through the testing platform, the system was able to obtain key parameters such as hydrogen concentration distribution, flame structure, thermal radiation intensity, and its range of influence. This allows for a clear understanding of the flow and diffusion patterns of hydrogen under high-pressure conditions, covering a wide range of scenarios including pressures from 1 MPa to 10 MPa, various standpipe heights, different standpipe diameters, and various configurations of flame arresters.
