Research 'converts' CO2 into fuel for aircraft, maintaining stable performance for 800 hours.
As global aviation fuel prices soar, Chinese scientists are accelerating efforts to commercialize technology that converts carbon dioxide into jet fuel—a breakthrough that could reshape both energy security and emissions reduction.
From Lab to Industry
On April 15, researchers at the Shanghai Advanced Research Institute, Chinese Academy of Sciences, published findings in ACS Catalysis outlining an industrial pathway to directly transform CO₂ into long-chain hydrocarbons—precursors for jet fuel.
The innovation arrives amid volatile energy markets: jet fuel prices hit $175 per barrel in March, up 94% year-on-year, and surpassed $200 in April, forcing airlines to cancel flights. With geopolitical tensions driving costs higher, CO₂-to-fuel technology is being viewed not only as a climate solution but also as a strategic safeguard for aviation.
How It Works
The process essentially reverses combustion: instead of burning fuel to release CO₂, it uses CO₂ and water as inputs, rearranging molecules into high-energy liquid fuel.
The challenge has long been producing carbon chains long enough—and of the right type—for aviation. To overcome this, the team designed an iron-based catalyst enhanced with potassium and aluminum, which self-forms a special interface during reactions. This interface proved key to generating hydrocarbons suitable for jet fuel.
Results: Efficiency and Durability
- At 330°C and moderate pressure, the catalyst produced 453.7 mg of heavy olefins per gram per hour, with 252.7 mg directly convertible into jet fuel.
- Crucially, the catalyst maintained stable performance for 800 continuous hours, signaling readiness for industrial-scale application.
The Academy described the method as a “relatively simple strategy” for producing high-carbon olefins and jet-range hydrocarbons with unprecedented efficiency.
Commercialization Challenges
Hu Shi, founder of Feynman Dynamics and professor at Tianjin University, cautioned that turning lab breakthroughs into certified aviation fuel is “a marathon.” Aviation requires rigorous certification for safety and sustainability, and CO₂-derived fuels are not yet officially recognized. He compared the process to drug development: promising lab results must still undergo extensive validation before widespread adoption.
Early Commercial Moves
Despite hurdles, commercialization is underway. In October, Feynman Dynamics signed an agreement with Inner Mongolia authorities to build a plant producing 3,000 tons of synthetic sustainable aviation fuel annually. Their approach combines electrocatalysis and thermocatalysis, using renewable electricity to split CO₂ into CO and oxygen, then applying the proven Fischer-Tropsch process to create liquid hydrocarbons.
Hu emphasized that electric-based fuel production is the most viable long-term solution for aviation. Aircraft cannot rely on batteries due to energy demands and flight endurance, making liquid fuels indispensable. Waste-oil-based sustainable fuels are already in use but limited in supply, whereas CO₂ offers a scalable feedstock.
If scaled successfully, CO₂-derived jet fuel could reach cost parity within a decade, transforming a greenhouse gas once seen as a burden into a reliable energy source for aviation. For an industry struggling with both emissions and soaring costs, this breakthrough could mark the beginning of a new era in sustainable flight.
