China has conducted a successful in-flight test of a hydrogen-powered engine, advancing sustainable aviation technology. On April 4, 2026, in Zhuzhou, a 7.5-ton unmanned cargo aircraft equipped with the AEP100 engine, developed by the Aero Engine Corporation of China, reached 300 meters altitude, flew for 16 minutes, covered 36 kilometers at 220 km/h.
The AEP100 burns liquid hydrogen in a turbine, similar to conventional kerosene engines but emitting only water vapor and producing zero carbon emissions during operation. This distinguishes it from many Western approaches focusing on hydrogen fuel cells.
The test represents an early real-world demonstration of hydrogen combustion in flight, unlike ground tests by Rolls-Royce and easyJet or fuel cell efforts by Airbus. Challenges remain, including infrastructure for hydrogen production, storage, and refueling, along with high costs and safety concerns for combustion engines.
Global aviation, consuming 7-8 million barrels of jet fuel daily, faces pressure to decarbonize amid oil dependence and rising prices. China's progress underscores efforts to reduce fossil fuel reliance and lead in green aviation.
