Danish shipping company Maersk is testing a blend of Brazilian ethanol with methanol and marine diesel for its vessel engines as part of its efforts to further decarbonize operations, the company announced on Monday.

The initiative could open a new market for Brazil's ethanol industry while helping to reduce the maritime shipping sector's carbon footprint, which currently accounts for about 3% of global greenhouse gas emissions.

Maersk, which represents 15% of the global maritime shipping market, is testing a blend with 10% of ethanol. If the whole industry adopted the fuel mix, it could create demand for 50 billion liters of ethanol globally per year. Brazil's expected production this year is around 35 billion liters.

"This is the first time ethanol is being burned in a two-stroke engine that's four stories tall - it's a completely different scale of research and level of concern," said Danilo Veras, VP of Regulatory Policies at Maersk Latam.

Maersk, which aims to achieve net-zero emissions by 2040, chose the Brazilian ethanol for the test because it comes from existing sugarcane areas or, when corn-based, mostly from the same fields as soybeans, lowering potential impacts for deforestation, according to Veras.

Maersk will complete ethanol blend tests in methanol-powered vessels by October 23, followed by bunker fuel testing. If successful, the company would begin negotiations with major Brazilian ethanol producers, including Raizen, Copersucar, Inpasa, FS and Atvos.
