A new development could help reduce the carbon footprint of air travel, which aims to reduce emissions by jets to zero. A team of Oxford University researchers has succeeded in converting carbon dioxide (CO2) into jet fuel, although so far the experiment has been performed on a very small scale. As climate change concerns grow, scientists have been working for years to convert CO2 into sustainable, synthetic hydrocarbon fuels for transportation purposes. So far, this reverse engineering has only been tested in the lab, but when introduced on a large scale, it can be a game changer.
A team of researchers has found a way to use low-cost iron catalysts to convert CO2 (or direct factory emissions) into the atmosphere into synthetic jet fuel. Scientists first developed the Fe-MN-K (Iron Manganese Potassium) catalyst using the Organic Combustion Method (OCM). It then demonstrates the conversion of CO2 to hydrocarbons by hydrogenation at 38.2% of the calist aviation jet fuel range and 5.6% of low carbon monoxide production. The conversion reaction also produces other by-products that are important raw materials for the petrochemical industry and are still derived only from fossil crude oil.
In this method, the carbon dioxide emitted from the air is used for conversion and later re-emitted from the jet fuel when it is compatible with the flight. As a result, the overall effect of this process is carbon neutral fuel.
So far, this process has remained within the walls of the lab. There are challenges that need to be overcome before a viable method of preparing aviation fuel can be developed. One of the barriers is carbon capture – the process of capturing carbon from the atmosphere. Activating CO2 is also a challenge. Another complication is that hydrocarbon synthesis by hydrogenation of CO2 generally favors the formation of short chains rather than the required long chain, which is essential for aviation fuel synthesis.
The new process represents a significant social development that highlights CO2 recycling and resource conservation as an important, critical aspect of greenhouse gas management and sustainable development. This catalytic process is expected to pave the way for achieving pure zero carbon emissions from the aviation industry in the near future – as long as we as a society are fully committed to operating environmentally friendly electric aircraft.
