China made a solar reactor that converts air and sunlight into jet fuel, directly


In a state-of-the-art facility in western China, researchers have demonstrated something almost alchemical: a compact solar-powered reactor that produces liquid jet fuel using just sunlight, air, and water. The prototype, built by a team at the Dalian Institute of Chemical Physics, converts carbon dioxide and water vapor into synthetic kerosene, without any fossil fuel input.

The system mimics photosynthesis but with extreme precision. Sunlight is focused using a heliostat array onto a high-efficiency thermochemical reactor containing cerium oxide. At high temperatures, the material strips oxygen from CO₂ and H₂O, breaking them into carbon monoxide and hydrogen — the building blocks of synthetic fuel.

These gases are then fed into a Fischer-Tropsch synthesis chamber, where catalysts assemble them into hydrocarbon chains — essentially manufacturing jet fuel molecule by molecule. The entire process happens in one compact, closed-loop system with no emissions, no need for crude oil, and no external energy input beyond sunlight.

In early tests, the reactor produced 1 liter of jet fuel per day — a small amount, but one that proves the entire pathway works. The team is now scaling the system to industrial levels, aiming for 1,000-liter-per-day modules that could be deployed at airports, solar farms, or even on remote islands.

What makes this revolutionary is not just the fuel — it’s the independence. No drilling, no refining, and no dependence on global oil markets. With only air, water, and sunlight, the reactor could someday power aircraft, drones, or cargo ships with zero-carbon fuel made on-site.

This isn’t science fiction — it’s now undergoing pilot testing with China’s aerospace partners. A clean jet age may begin not in the sky, but in a sunlit lab on the ground.
