New alternative fuels will not be economically viable until 2040, according to Maritime Strategies International (MSI).

Managing director Adam Kent told the Marine Money Ship Finance Forum in London that his company had been examining when it would make economic sense for owners to make the switch to green ammonia or methanol, given consensus assumptions about future prices and carbon levy levels.

The analyst said: “Unfortunately, it is not until around the end of the next decade that it becomes more economically viable to run green fuels than conventional fuels, or conventional fuels with a scrubber.”
