Shipping is currently in the midst of a structural transformation driven by climate policy, technology development, and investment pressure. The International Maritime Organization( IMO) has set increasingly ambitious emissions reduction targets, while the European Union’ s regulatory framework is further accelerating the shift toward low- and zero-carbon fuels.
Unlike previous technological transitions in shipping, the current phase is characterized by uncertainty over which fuel pathways will ultimately dominate. Instead, multiple parallel solutions are being developed and deployed at the same time, each with distinct advantages, limitations, and readiness levels.
The key question is no longer whether alternative fuels are needed, but rather which technologies are worth investing in under conditions of long-term uncertainty.
METHANOL EMERGES AS A PRACTICAL CONTENDER
In recent years, methanol has strengthened its position as one of the most commercially viable alternative marine fuels, particularly in the deep-sea container seg-
