AP Moller Maersk is expanding its exploration of ethanol as a marine fuel by trialling a higher ethanol blend on board the container vessel Laura Mærsk, as part of efforts to diversify its low-emission fuel options.
The company said it will test a 50/50 ethanol-methanol blend after earlier trials using a 10% ethanol and 90% e-methanol mix showed ethanol could be safely integrated without compromising engine performance.
Laura Mærsk, the world’s first dual-fuel container ship capable of operating on methanol, is fitted with an alcohol-fuelled engine, allowing ethanol and methanol to be used in combination with minimal modification.
Maersk said this effectively creates additional optionality for its growing dual-fuel methanol fleet.
“At Maersk, we believe multiple fuel pathways are essential for the shipping industry to meet its climate ambitions,” said Emma Mazhari, Head of Energy Markets at Maersk.
Maersk said it also plans to trial 100% ethanol, with the tests aimed at assessing engine performance, fuel availability and emissions impacts.
