China's hydrogen-powered turboprop engine aces ground tests in 2026
China has successfully tested its first megawatt-class liquid hydrogen turboprop engine. The AEP100, developed by the Aero Engine Corporation of China (AECC), completed full ground tests on 29 March 2026. This milestone marks a key step toward cleaner aviation technology in the country. The engine was designed by AECC's Hunan Aviation Powerplant Research Institute in Zhuzhou. During testing, all performance indicators—including the liquid hydrogen transport system—remained stable and within normal ranges. The AEP100 underwent ignition trials and performance adjustments under simulated flight conditions, proving its reliability.
Liquid hydrogen offers high energy density and produces zero carbon emissions, making it an attractive alternative for reducing aviation's environmental impact. The successful validation confirms the engine's technical feasibility and aligns with China's push for sustainable aerospace solutions.
AECC plans to pursue airworthiness certification for the AEP100 later in 2026. The technology will initially target unmanned logistics and regional aircraft before potentially expanding to larger commercial aviation. Development efforts will focus on engineering applications and market adoption during the 15th Five-Year Plan (2026–2030). The AEP100's ground tests confirm its readiness for further development. With airworthiness certification expected this year, the engine could soon enter service in niche aviation sectors. Over time, the technology may support a broader shift toward hydrogen-powered flight in China.
