Scientists turn CO2 into jet fuel

The approach is inexpensive, uncomplicated and uses everyday materials. It is cheaper than processes used to turn hydrogen and water into fuel.

There are numerous challenges in bringing it to airplanes. The laboratory method yielded only a few grams of fuel – you clearly need much more to support even a single flight, let alone an entire fleet. You need a lot more use of carbon capture. And if you effectively want no emissions, the capture and conversion systems must operate on clean energy.

However, the investigations speak to industrial partners and see no major scientific barriers. It can also be one of the most viable options for fleet. Many of them will have to replace their aircraft to become electric or switch to fuel type. Through this conversion process, airlines can maintain their existing aircraft and remain carbon neutral until they are truly ready for environmentally friendly propulsion.
