Petrobras tests a Marine Fuel with 24% renewable content, The new fuel has the potential to reduce greenhouse gas emissions by around 17%.

Petrobras has begun testing the performance of Bunker fuel with 24% renewable content by volume. It is being used to fuel a ship, located at the Rio Grande (RS) Terminal and chartered by the company, Transpetro. The estimated percentage reduction in greenhouse gas emissions would be around 17% by volume, compared to standard mineral bunker fuel, based on a preliminary analysis of the complete lifecycle of the product.

It is the second test by the company on this type. However, this time, the percentage of biodiesel is higher than in the first test, when the percentage was 10% by volume. The renewable portion of the fuel was produced from 30% animal fat (tallow), by volume, plus 70% from soybean oil.

According to Claudio Schlosser, Petrobras Director of Logistics, Commercialization and Markets, the progress with the testing of bunker fuel with renewable content shows how the company is taking a clear position: “We are currently investing in new products that will bring environmental benefits for society. The results from the first test, where we mixed bunker fuel with 10% renewables, indicated that there was scope to increase the percentage. Now that 24% of the fuel is biodiesel, we can show that the energy transition is definitely on Petrobras’s agenda”.

Maurício Tolmasquim, the Director of Energy Transition and Sustainability, added: “This test is increasing the number of options we can offer our customers that will allow them to achieve decarbonization and diversify our product portfolio. The marine fuel industry is looking for quick wins that we can provide.”

For Carlos Travassos, Petrobras Director of Engineering, Technology and Innovation, advanced biofuels stand out as one of the best options to replace fossil fuels in the maritime transport industry, especially long haul,  since the issues with electrification in this area are more significant. “In the coming decades, these biofuels could provide an important competitive advantage for Brazil, not just because we have the land and agricultural production to supply them, but also due to Petrobras’ proven ability, through its Research Center, to develop technology that makes the most of the qualities of the region and utilizes existing infrastructure”.

The next test will take two months to complete

The vessel has been filled with around 573,000 liters of fuel. The operation took place at the Transpetro terminal (Terig), in the city of Rio Grande (RS). The vessel is chartered by Petrobras from Maersk Tankers and is used on cabotage routes along the Brazilian coast. Over the next few months, the ship’s data will be monitored, including consumption, power produced and distance traveled, along with how the fuel performs in relation to the filters and purification systems.

According to Sérgio Bacci, the president of Transpetro, the company is supportive of Petrobras in its development of a more sustainable generation of products: “Transpetro is working with Petrobras to test the bunker fuel with renewable content. We are working to make these unprecedented operations possible in Brazil because we are committed to working with our parent company to establish the energy transition for our future. Transpetro excels in innovation and is the only oil and derivatives logistics company in all of Latin America that is capable of providing sustainable solutions like this”.

The formulation is based on a mixture of mineral bunker fuel (as specified under ANP resolution) and biodiesel produced by Petrobras Biocombustível (PBio) at the Montes Claros Plant (MG). For Rodrigo Pimentel Leão, the president of Pbio, “the current test is testimony to the ability of our different areas to work together. Pbio has shown that it is committed to developing products with less carbon, by producing the biodiesel for the vessel”.

The first test, at the start of the year, showed that it was a viable fuel

The first test carried out by Petrobras lasted 40 days, between December 2022 and February 2023. During this time, the vessel, Darcy Ribeiro, owned by Transpetro, used around 303,000 liters of a mixture of bunker fuel and 10% biodiesel, by volume. The results did not indicate any abnormalities in the running of the engine, nor in the fuel treatment systems (centrifuges and filters).

The operational parameters, the fuel quality analysis and the stability of the mixture indicated that the product was viable and there was scope for further testing of greater percentages of renewables with the bunker fuel.

Investing in Low Carbon

Recently, Petrobras has approved the guidelines for its 2024-28 Strategic Plan, which is due to be announced in November of this year. The strategic elements of the new plan are designed to ensure that Petrobras is ready for a more sustainable future, and work towards a fair and safe energy transition in this country, by reconciling the current focus on oil and gas with the need to diversify the portfolio with additional low carbon business.
