Fossil fuels could soon be replaced by a product made with solar energy, carbon dioxide and water: this is the purpose undertaken by a group of researchers from the University of Uppsala, Sweden.
The process involves the use of appropriately modified cyanobacteria, thanks to which it is possible to produce butanol using solar energy but without resorting to solar cells. The sector related to the use of modified bacteria to produce different chemicals using carbon dioxide and solar energy is emerging more and more powerfully and more and more laboratories around the world are experimenting with new methods and new combinations to make the process more and more efficient.
Even the same production of butanol with this process had already been identified by past research but in the study carried out by the researchers of the Swedish Institute the production, according to the same statement published on the website of the Swedish University, is significantly higher.
Butanol can be used as a fuel, for example for traveling vehicles, and is considered a fourth-generation biofuel. It is a carbon-neutral fuel whose creation is totally sustainable since only solar energy, carbon dioxide and water are needed.
The procedure uses cyanobacteria, the most efficient photosynthetic organisms, to capture the energy of the sun.
