Marine Fuel Guide

Methanol — CH₃OH Marine Fuel

Methanol is an emerging marine fuel gaining attention as a pathway to deeper decarbonisation than LNG can offer. Liquid at ambient conditions (unlike LNG), it uses simpler onboard storage and bunkering infrastructure. Green methanol (from renewable electricity and captured CO₂) is effectively carbon-neutral; blue methanol (from natural gas with CCS) reduces emissions versus fossil fuel.

Purpose-built methanol dual-fuel vessels — notably Maersk's growing container fleet and a number of tankers and bulkers

Technical Detail

Supply chain maturity

The Maersk orderbook for methanol dual-fuel container vessels has been a major driver of methanol infrastructure investment. Rotterdam offered commercial green methanol bunkering in 2023-2024; Singapore, Shanghai, and other hubs are following.

Green vs grey methanol

'Grey' methanol is produced from natural gas — abundant and cheap but carbon-intensive. 'Green' methanol uses renewable power for electrolysis (hydrogen) and captured CO₂ — genuinely low-carbon but expensive and supply-constrained. 'Blue' methanol uses natural gas with carbon capture. Pricing and availability differ dramatically between these categories.

Storage and safety

Methanol is liquid at ambient temperature, simplifying storage versus LNG. It is toxic, miscible with water, and flammable with a wide flammability range. Onboard safety systems and crew training are required under IMO interim guidelines.

Cost and availability

Green methanol is significantly more expensive than VLSFO and global supply is limited. Most operational green methanol supply is currently committed to specific industrial offtake agreements rather than open-market sale.

Frequently Asked Questions

Can existing engines run on methanol?

Most cannot without modification. Methanol-capable engines are dual-fuel (methanol plus diesel pilot fuel) and purpose-designed or retrofit. New methanol-ready orderbook vessels are the growth category.

Is methanol carbon-free?

Depends on production pathway. Green methanol (renewable electricity + captured CO₂) is effectively net-zero lifecycle. Grey methanol (from natural gas) is not. The certification chain matters for regulatory credit.

Where can I bunker methanol?

Rotterdam, Singapore, and a small but growing list of ports. Most bunker stems today are bilateral arrangements with specific suppliers rather than spot market. Confirm at nomination.

How does methanol cost compare to VLSFO?

Green methanol is typically 2-4× more expensive per energy unit than VLSFO. FuelEU Maritime and EU ETS compliance value can offset some of this; long-term pricing depends on renewable supply chain maturity.
