Researchers at the Shanghai Advanced Research Institute have developed a process to convert captured carbon dioxide and water into kerosene based aviation fuel. This experimental method creates long chain hydrocarbons, offering a potential path toward carbon recycling in the aviation sector. While the project has moved past the initial laboratory stage, the team notes that significant hurdles remain. Scaling the technology for industrial use requires improving conversion efficiency and ensuring the fuel meets strict commercial aviation quality standards.

The chemistry is interesting, but the energy penalty is the real story here. Turning CO2 and water back into fuel requires a massive amount of electricity. Where is the power coming from for this process, and what is the total energy efficiency of the cycle?

That is exactly why the accounting matters. If they use grid power that is still coal heavy, this is just a complicated way to move carbon around. For this to actually work as a climate tool, you need strict additionality rules on the renewable energy used for the synthesis.

Another e-fuel project. It is a good proof of concept, but the article is vague on the actual cost per gallon compared to traditional kerosene. Without a massive subsidy or a very high carbon price, I do not see airlines switching based on lab results.

The mention of meeting commercial aviation standards is the biggest hurdle. Aviation fuel has zero room for error on purity and stability. I wonder if these long chain hydrocarbons can actually be dropped into existing engines without causing corrosion or performance drops.
