**China has successfully launched a Long March-12 rocket using a new high-energy synthetic kerosene that boosts payload capacity by 10 percent**, marking a breakthrough after 13 years of development by the Beijing Aerospace Test Technology Research Institute. The fuel, developed by a subsidiary of the China Aerospace Science and Technology Corporation, increases specific impulse by around eight seconds, allowing rockets to carry hundreds of additional kilograms of payload. This innovation comes as China ramps up lunar missions and commercial satellite deployments, seeking to maximize performance without building larger, more expensive airframes.</p><p class="summary-lead">**The new fuel overcomes the performance limits of traditional liquid oxygen-kerosene engines**, which have plateaued with refined petroleum blends. Researchers tackled complex engineering challenges including efficient synthesis, precision purification, and heat-transfer coking control, then scaled production to a 400-tonne annual capacity with plans for a 2,000-tonne facility. The team also developed a smart fueling system to counter Hainan’s corrosive heat, humidity, and sea salt, ensuring reliable launch operations.</p><p class="summary-lead">**This advancement has major implications for both Chinese and global launch industries**, as kerolox engines remain the standard for vehicles like China’s Long March-5, -6, and -7, as well as SpaceX’s Falcon 9 and Falcon Heavy. The fuel could enable heavier commercial satellite payloads and more ambitious deep-space scientific instruments without redesigning rocket airframes. China’s first privately developed liquid-fuel rocket, the Tianlong-2, already uses a coal-derived synthetic kerosene, signaling a broader shift toward high-density propellants.</p><p class="summary-lead">**What to watch next:** Whether this synthetic kerosene can be adopted by other launch providers, including SpaceX, and how China’s planned 2,000-tonne production facility will impact global fuel supply chains and launch costs.
