Depending on how it is calculated, the climate impact of air travel ranges from less than 1% to around 5%. But what is certain is that it is basically a resultThe that power our aircraft’s reactors. Because kerosene is produced by The a fossil. It emanates from combustion (Ko2), the main Responsible for mankind. At the moment, unfortunately, there is no clean alternative that would make it possible to think about maintaining long-distance air traffic on a global scale.
At the present time .. because scientists are far from admitting defeat in the field! One of the most promising avenues is the production of so-called solar fuels. The idea is to produce synthetic fuel fromSolar. It is possible by the photochemical method, by activating reactions thanks to which carries solar energy, or photobiological, understands Artificial, for example. But also in a thermochemical way.
This is the path that(ETH, Switzerland) Chose Explore. They are now offering a fuel production system that they hope will help the aviation sector become carbon neutral. A solar tower that produces jet fuel from water and .
This tower consists of 169 track-tracking boardsBy reflecting and focusing the radiation towards a reactor located above. This energy then makes it possible to trigger cycles of reactions On a porous oxide structure (Executive Director2) – a compound that is not consumed in the process – to convert water and carbon dioxide2 It is injected into the reactor as a synthesis gas which is then converted into kerosene.
Efficiency can be improved
So far, these attempts have remained in the laboratory stage. This time, the researchers succeeded in proving the feasibility of the entire series onIndustrial. from CO2water and From the sun they can produce kerosene.
Kerosene? but after thatthan before. yes. But the solar tower developed by ETH researchers consumes the same amount of carbon dioxide2 Aircraft then emit. What finally makes fuels carbon neutral. A little more even when it can be produced from carbon dioxide2 Captured live in .
Another advantage is that solar kerosene is fully compatible with existing infrastructures. Infrastructures for storage, distribution and use. If necessary, it can be mixed with original kerosene.
Only downside, finally,From the solar tower. Today it is only about 4%. But the researchers already have ways to improve their design. They hope to increase it to 15%.
