Biodiesel in Marine Fuels: A New Milestone

By Alexandre Vilela

ANP (National Oil Agency) authorization to sell bunker fuel with up to 24% biodiesel. Building on the success of 2022 tests with 10% biodiesel, which achieved a 7% reduction in emissions, the new B24 blend is expected to achieve an impressive 17-19% reduction in emissions.

This initiative aligns with the current PSV new building tender, where the use of biofuels is mandatory. Petrobras is committed to completing an industrial cycle where engine manufacturers will ensure that the added biodiesel does not compromise engine guarantees — addressing a significant challenge faced by owners during this transition phase.

The B24 biodiesel blend primarily consists of soybean and bovine tallow oils. Notably, the ANP authorization is exclusive to Petrobras, with the biodiesel blending to take place at Petrobras terminals instead of refineries, ensuring stringent control measures.
