China: Liquefied natural gas-derived methane used as rocket fuel for first time

China's space program has reached a significant technological milestone with the successful application of methane, derived from liquefied natural gas (LNG), as a fuel for the Long March 10B rocket. This high-purity methane fuel, produced from domestic LNG resources, marks its first large-scale use in space launch vehicles.

The development signifies crucial progress in China's commercial space sector and its drive to diversify fuel supplies. The Long March 10B is a two-stage, reusable launch vehicle specifically designed for commercial space market demands. Its core stage measures 5 meters in diameter, with all essential components being domestically sourced.

The methane fuel, boasting a purity of 98.7% for this launch, offers a more cost-effective and frequent launch solution compared to traditional fuels like liquid hydrogen. Its storage and transportation costs are estimated to be 40% lower, providing a viable new fuel option for the commercial space industry.

The successful implementation of this fuel supply chain, leveraging domestic LNG capabilities, strengthens China's position in the space fuel market. It establishes an economically efficient and lower-carbon footprint fuel solution, enhancing the independent development and core market competitiveness of China's commercial space industry.
