Shipping decarbonization is entering a phase of practical implementation with multiple alternative fuel pathways. However, shipowners are adopting cautious and case-specific fuel strategies to balance compliance, operational flexibility, and commercial risk. Within this context of uncertainty, a limited number of fuel pathways have progressed beyond concept into operational use. Among these, methanol has emerged as one of the most prominent, already being applied in practice.
Methanol offers a credible route to lower lifecycle greenhouse gas emissions where low-carbon methanol production is available. Despite this progress, there remains limited public information on how methanol performs in day-to-day operation and what is needed for it to be managed effectively in service.
This report addresses that question from the perspective of operational practice. It is intended for shipowners, managers, charterers, ports, regulators, and other stakeholders moving from concept evaluation to implementation. It draws on direct experience from first movers across the value chain– vessel operators, shipyards, original equipment manufacturers (OEMs) and ports who have commissioned, operated, and supported methanol-fueled vessels in service. The analysis spans areas such as vessel design, training and competence, operational performance, maintenance, safety management, emergency response, and the port and bunkering interface. A central premise of this report is that the most useful lessons come from execution—how systems behave in practice, how crews interpret and respond to them, and how procedures evolve over time. These insights determine whether a fuel is not only technically feasible, but operationally reliable in commercial service.
