For some months now, the aviation market has been looking for ways to make the supply of aircraft more sustainable. One of the alternatives being studied was the use of ethanol, which would be the most viable way to reduce carbon emissions.

With this in mind, after several studies, the EPA, the US Government agency responsible for environmental protection in the country, authorized the use of biokerosene as fuel for fueling aircraft.

Alternative Fuels
Until then, SAF fuel was used as an alternative, which has different components, such as recycled materials and cooking oil.

But when studies on the use of ethanol began, it proved feasible to add this compound to the AFS and transform it into a more efficient and sustainable fuel.

Considering this, the use of biokerosene was recently approved in the United States, which is nothing more than a biofuel produced from Brazilian ethanol.

This compound is generated from sugarcane and, in 2010, it was classified by the EPA as a promising biofuel. This is because it reduces greenhouse gas emissions by 50% when compared to conventional fuels.

With the country's approval and the recent global interest in adopting more sustainable measures, there are great possibilities for this biofuel to start being accepted and used in large proportions in the rest of the world.

And after all, can electrical energy be used?
When it comes to fuel, the question generally arises as to why not use electrical energy to supply aircraft? This is a viable alternative. However, it could only be implemented with electricity from batteries built into planes.

And that would be the biggest problem, because to provide enough energy to the plane, the batteries used would be very bulky, but mainly heavy! This would interfere with the autonomy that the plane needs to have for locomotion.

Thus, the most viable and sustainable alternative at the moment remains biokerosene.
