E-fuel benefits for the transport sector

There is no doubt that more and more the movement towards clean transport gains more strength. Many companies still believe that the internal combustion engine still has a lot of fuel to burn. However, this fuel needs to be sustainable, produced from renewable sources. Germany, for example, is developing advanced synthetic fuels, which are produced without oil, using water and carbon dioxide available in the atmosphere as raw materials.

Called "e-fuel", fuels can be extracted in the form of gasoline or diesel and therefore do not require changes in the current engines that use the fossil version of these fuels. Audi, for example, which named its product "e-benzene," reported that the liquid emits fewer pollutants and allows higher compression rates for higher performance.

In an interview with UOL, Everton Lopes, technology mentor at SAE Brazil, said that fuels have the advantage, such as ethanol, of "neutralizing" the carbon resulting from their burning, in addition to taking advantage of the supply infrastructure. 

The manufacture of e-fuel goes through a hydrolysis process, which removes hydrogen from water for combination with CO2. The resulting gas is then used to produce hydrocarbon chains that will become liquid fuel. "The challenge is the large amount of electrical energy needed to separate the hydrogen present in water. This energy should preferably be of clean origin, such as solar, wind or hydroelectric plants," Lopes said.
