Petrobras’ New Fuel Promises to Enable the Use of Higher Levels of Renewables in New Diesel Combustion Engines
Petrobras informed the market in a relevant fact this Thursday (29) that it completed this September the first sale of R5 Diesel produced by the company for commercial testing. The production of the fuel reached a total of 1,500 m³ at the Presidente Getúlio Vargas Refinery (Repar), located in Curitiba.
The Fuel Produced from Co-Processing of Vegetable Oils Also Known as Green Diesel
R5 Diesel is produced from the co-processing of vegetable oils, in this case, refined soybean oil, along with petroleum diesel. The fuel leaves the refinery with 95% mineral diesel (derived from petroleum) and 5% renewable diesel, also known as green diesel. Distributors will add 10% of ester biodiesel, as established by current legislation.
A novelty in the marketed batch was the issuance of statements for the distributors who acquired the product, indicating the reduction in greenhouse gas emissions, calculated according to the volume purchased by the distributors. In the case of R5 Diesel, it potentially prevents the emission of one ton of CO2 equivalent for every approximately 9,500 liters, compared to 100% fossil fuel.

Naturgy begins an investment of R$ 1.6 million to expand the gas network in Niterói and benefit thousands of new residences and businesses.
According to Petrobras’ report, the calculation includes emissions from fossil fuel during the extraction, production, and usage stages. For the emissions from the renewable content, the calculations include the production of raw material, extraction of vegetable oil, co-processing at the refinery, and final usage. It also includes intermediate transportation between all these stages.
Currently, the National Energy Policy Council (CNPE) is discussing the possibility of this newer renewable fuel, produced in dedicated units or through co-processing with vegetable oils, also being considered in the biodiesel mandate present in diesel sold at fuel stations.
If accepted, the introduction of the new fuel will enable the use of higher levels of renewables in new diesel engines; also increasing the competitiveness of the supply of biofuels in Brazil,” Petrobras said in the statement.
