Under this project, and as a way to meet the challenge of decarbonization, we aimed to produce biojetfuel for the aviation sector, through two ways:

(1) from the autotrophic production of microalgae, which are then subjected to a hydrothermal liquefaction process with production of a bio-oil that by hydro-deoxygenation is converted into hydrocarbons, giving rise to biojetfuel;

and

(2) through the industrial production of biojetfuel from microbial oils produced by heterotrophic fermentation of hydrolysates from residual biomass of forest nature.

In terms of road transport, the focus was on hydrogen-based biofuels (BioH2) and biomethane (BioCH4). BioH2 and BioCH4 can be produced in various ways, but both molecules participate in the production of one and the other. BioH2 can be produced from BioCH4 by steam reforming and water gas shift, with some of the BioCH4 being used to power the production system. On the other hand, BioCH4 can be recovered from landfills, but also produced by “methanation” from the recovery of biogenic or non-biogenic CO2 and sustainable H2 produced by water electrolysis using solar or wind power.
