Japan Conducts First Ship-to-Ship Methanol Fuel Transfer in Yokohama

On February 6, 2026, Japan achieved a milestone in maritime energy transition with its first successful ship-to-ship methanol fuel transfer. This operation, a public-private collaboration involving five stakeholders, took place at the Yokohama Keihin Port. Methanol fuel was transferred from a coastal tanker to a dual-fuel deep-sea vessel, marking a strategic advancement in operational flexibility for ship operators. The methanol used includes both fossil-based and domestically produced bio-methanol, highlighting Japan's shift towards local production of alternative fuels.

This capability allows ships to refuel while at anchor, improving operational flexibility and reducing port congestion. The methanol included domestically produced bio-methanol, positioning it as a carbon-neutral energy source.

The operation indicates a shift towards localized fuel supply chains, with Japanese maritime companies increasing their fleet of alternative fuel vessels. The successful transfer required a comprehensive regulatory framework established by Japan's transport and port authorities. The operation aligns with Yokohama's Carbon Neutral Port initiative, aiming for reduced emissions in marine energy systems.
