The state-owned company is seeking to make the new green bunker viable with the addition of biodiesel in its composition for the maritime transport sector. The first vessel to be supplied in Petrobras' first tests was Darcy Ribeiro, from Transpetro.

The state-owned oil company Petrobras recently carried out tests on the use of its new green bunker, which has 10% biodiesel in its composition. The company was at the Rio Grande Terminal (Terig), in Rio Grande do Sul, where the Darcy Ribeiro vessel, from Transpetro, was supplied with the new fuel. Now, the tests will continue for about two months to assess the logistical risks of using their new bunker.

Petrobras has been seeking to implement its new green bunker, with 90% of the original mixture and 10% of biodiesel in its composition, in the national transport market.

Thus, in the last week of 2022, the first supply tests were carried out to verify the feasibility of the fuel.

The vessel Darcy Ribeiro, belonging to the Transpetro company, was the first to be supplied with the mixture, and will spend the next 2 months serving as the basis for the logistical tests for the use of the new green bunker.

“The renewable fraction of the new fuel has the potential to reduce greenhouse gas emissions relative to the bunker when considered over the full life cycle. The estimated percentage reduction of CO2 equivalent emissions from this mixture is around 7%”, highlighted Petrobras in a statement.

The new green bunker was developed at the Petrobras Research and Development Center (Cenpes) and, until then, no problems had been observed in meeting the main specific properties of the fuel.

Thus, the first tests with Transpetro will serve to verify the real viability of using the mixture in navigation operations.

The evaluations of the burning quality and the stability of the mixture indicated the approval for the field test in a marine vessel.

The new bet by the state-owned company for the transport market aims to guarantee even more environmental commitment, since the company hopes that the inclusion of biodiesel will encourage the reduction of carbon dioxide (CO2) emissions by around 7% in operations.

What is Petrobras' bunker?

Petrobras sails in distant seas with its fuels for the maritime transport of cargo and passengers. They are provided through bunkering services by barges or pipelines, supplying vessels moored or anchored in the main Brazilian ports, both those that operate in cabotage along the Brazilian coast and the long-haul vessels that travel along our coast.
