China has completed its first full-scale high-pressure pure hydrogen pipeline leak and jet fire test. The month-long trial in Xinjiang Uygur Autonomous Region involved 33 different leakage scenarios to collect critical data on flame characteristics and thermal radiation. A key innovation was the first-ever coordinated use of fire-breathing drones and a remote high-voltage electronic ignition system. The results are vital for establishing safety standards and supporting the large-scale transportation of hydrogen energy.
