China makes jet fuel from CO₂ in trial
A Tsinghua-led installation with industrial partners ran for 72 hours at a thousand-tonne scale, but commercial and climate benefits remain unproven.
Chinese researchers have operated a pilot plant for synthetic jet fuel made from CO₂ and hydrogen for an extended period. The performance has been assessed by a Chinese expert committee, but the technology has not yet led to commercial fuel production.
The installation is located in Meishan in Sichuan province and was developed by a team from Tsinghua University and industrial partners. According to Tsinghua, it ran continuously at full load for 72 hours. The pilot plant operates at a thousand-tonne scale, considerably larger than a laboratory set-up but much smaller than a commercial refinery.
The researchers use CO₂ as a carbon source and hydrogen as a feedstock. Using a so-called bifunctional catalyst, the CO₂ is converted into hydrocarbons that can serve as a component of jet fuel. Tsinghua reports a CO₂ conversion rate of 97.37 per cent and a selectivity of 92.37 per cent for the desired heavier hydrocarbons.
The China Petroleum and Chemical Industry Federation organised the assessment. According to Tsinghua, the committee found that the product met the Chinese standard for jet fuel and recommended a larger-scale demonstration plant. This is an industrial assessment, not an independent peer review of all the claims, nor proof that the fuel is climate-neutral over its full life cycle.
Much depends on the origin of the hydrogen and electricity for the climate impact. If they come from fossil sources, production may deliver far less climate benefit than the term sustainable aviation fuel suggests. A recent open-access study on China also highlights bottlenecks involving costs, feedstocks, scalability and certification.
The route could nevertheless offer an alternative to fuels made from used oils and fats, whose availability is limited. It could also put industrial CO₂ to useful use. For airlines and fuel suppliers, however, questions remain about price, international certification, energy use, infrastructure and the origin of the CO₂. The Chinese trial mainly shows that a technical process is possible at an intermediate scale; it does not yet prove that the system is the best choice economically or for the climate.
One story, several perspectives
What is established
- A Chinese pilot plant made jet fuel from CO₂ and hydrogen.
- The installation ran for 72 hours and operated at a thousand-tonne scale.
- The climate benefit depends on the energy and feedstocks used.
Left
Arguments Synthetic fuel may be necessary for aviation that is difficult to decarbonise, but public support must go hand in hand with lower fossil-fuel demand and strict oversight of the climate balance. Otherwise, carbon capture becomes an excuse to leave aviation growth unchecked.
Values Emissions reduction, ecological limits and climate justice.
Consequences Targeted use could limit emissions; broad subsidies without conditions could waste scarce green electricity.
Centre
Arguments The technology deserves a place in pilot projects and international certification, as long as independent life-cycle analyses and transparent standards determine which fuel is genuinely sustainable.
Values Technological progress, evidence and feasibility.
Consequences A phased approach could encourage innovation without already declaring one production route the winner.
Right
Arguments The trial shows that companies and researchers with industrial space can scale up quickly. Governments should primarily organise competition and energy supply rather than commit themselves to one technology.
Values Innovation, energy security and market forces.
Consequences Fewer regulations could accelerate investment, but without binding standards there is a risk that fossil energy will be sold as green.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

The technical figures are clearly attributed to Tsinghua and are not presented as independently proven climate benefits. Independent literature instead supports the uncertainties described around costs, energy and scalability.

Editor's note
The pilot plant and the performance figures reported by Tsinghua have been confirmed by the university. The assessment is industrial and not the same as peer review; the full climate balance and commercial viability remain uncertain.Sources
