Maersk is accelerating efforts to decarbonize marine operations with the launch of the world's first carbon-neutral liner vessel in 2023 – seven years ahead of the 2030 initial ambition. All future Maersk-owned newbuildings will have dual fuel technology installed, enabling either carbon neutral operations or operation on standard very low sulphur fuel oil (VLSFO). Maersk will continue to explore several carbon neutral fuel pathways and expects multiple solutions to exist in the future. Methanol, ethanol, alcohol-lignin blends and ammonia are the major candidates because of their potential to scale. The technology is now available; securing a competitive global supply chain through the fuel value chain is the main challenge now and stakeholders must cooperate to meet the demand.
