Green Bunker Fuel — Zero-Carbon Marine Bunkering

The fuels

Three green bunker fuels
now entering commercial deployment

The challenge of decarbonising deep-sea shipping is unique: vessels carry thousands of tonnes of fuel for journeys lasting weeks. Only liquid or easily liquefied fuels with near-zero lifecycle GHG emissions qualify. Three are now viable.

Primary pathway · 2025–2035 🟢

E-Methanol

Synthetic methanol (CH₃OH) produced from renewable hydrogen and captured CO₂. The leading green bunker fuel of the 2020s — liquid at ambient temperature and pressure, compatible with modified existing tank infrastructure, and already in commercial use aboard Maersk's dual-fuel fleet.

Liquid at ambient temperature · easiest bunkering of all zero-carbon marine fuels
Maersk + CMA CGM: 100+ dual-fuel methanol vessels ordered
Kassø (European Energy, Denmark): 42,000 t/yr production · supplies Maersk
If natural H₂ from Lorraine reaches €0.50/kg, e-methanol approaches fossil methanol cost parity

2× FuelEU multiplier until 2033 🔵

E-Ammonia

Green ammonia (NH₃) produced from renewable hydrogen and atmospheric nitrogen via Haber-Bosch. Zero carbon content — no CO₂ at combustion. The fuel with the highest long-term potential for deep-sea decarbonisation. Yara Eyde: the world's first commercial ammonia-powered container ship, Oslo–Hamburg route, 2026.

Zero carbon content · only water and nitrogen oxides at combustion (manageable)
2× FuelEU Maritime compliance multiplier until 2033 · first-mover economic advantage
NEOM Green Hydrogen Project: 1.2 Mt/yr green ammonia from 2027 (Saudi Arabia)
Air Products + Yara: global distribution agreement in advanced negotiation · 2026

Bridge fuel · existing fleet 🟡

Bio-LNG / Synthetic LNG

Liquefied natural gas from biomethane or Power-to-Gas sources. Uses the world's existing LNG bunkering infrastructure — thousands of terminals and bunkering vessels. The practical transition fuel while e-methanol and e-ammonia scale up to volumes required by the global fleet.

Largest existing bunkering infrastructure of all alternative marine fuels
CMA CGM + MSC: world's largest dual-fuel LNG container fleets
Synthetic e-LNG (Power-to-Gas + liquefaction) = zero-carbon long-term version
GHG reduction: −20% to −80% vs HFO depending on biomethane source and methane slip

Fuel	Volumetric energy density	Storage temp.	Bunkering infrastructure	FuelEU status 2025
🟢 E-Methanol	15.6 MJ/L	Ambient (liquid)	Modest retrofit of existing tanks	Fully eligible · mandated
🔵 E-Ammonia	11.5 MJ/L	−33°C (LPG grade)	Specialised · toxic · new training	2× multiplier until 2033
🟡 Bio-LNG	22.2 MJ/L	−162°C (cryogenic)	Largest existing infrastructure	Eligible · biomass limits apply
⚪ Liquid H₂	8.5 MJ/L	−253°C (cryogenic)	Infrastructure essentially absent	2× multiplier fuel cells

Global bunkering

Where green bunker fuels
are available today

Green bunker fuel availability is growing rapidly, concentrated at Europe's major hub ports and expanding to Asia-Pacific. The bunkering network is still thin — but it is being built at pace.

The regulation

FuelEU Maritime:
the regulation that makes green bunkering mandatory

FuelEU Maritime entered into force on 1 January 2025. It is not a voluntary framework — it applies to all ships above 5,000 GT calling at EEA ports, regardless of flag state.

January 2025

FuelEU Maritime in force

−2% GHG intensity vs 2020 baseline · EU ETS shipping coverage at 40% · Maersk methanol fleet operational · Yara Eyde in final preparation

2026 · Now

EU ETS full intra-EU coverage · Yara Eyde enters service

100% intra-EU voyage emissions in ETS · Yara Eyde Oslo–Hamburg commercial service begins · NEOM construction >90% complete · Air Products + Yara distribution negotiations ongoing

2027

NEOM production begins · Major fleet orders accelerate

1.2 Mt/yr renewable ammonia from NEOM · first commercial green ammonia at scale for maritime · fleet owners place methanol and ammonia vessel orders to meet 2030 compliance

2030

−6% GHG intensity · Green fuels economically critical

ETS carbon price + FuelEU penalty combine to make green bunker fuels cost-competitive with HFO for many routes · major bunkering hubs operational in all major maritime regions

2033

End of 2× e-ammonia multiplier

First-mover window for e-ammonia closes · operators with early supply agreements have locked in compliance advantage · ammonia engine technology mature and commercially available

2050

IMO net-zero · −80% FuelEU

Every ship ordered today will still be sailing · near-zero GHG fuels required across the entire global fleet · green bunker fuels the only scalable pathway

Why e-methanol and e-ammonia — not batteries or compressed hydrogen

Energy density — ocean crossings require weeks of fuel at thousands of tonnes · batteries are physically not feasible for vessels above ~500 GT on routes longer than ~100 km
Compressed hydrogen — storage at 700 bar or liquefaction at −253°C adds prohibitive cost and complexity for commercial vessels · not viable at scale before 2040
Drop-in compatibility — dual-fuel MAN ES and Wärtsilä engines run on methanol or ammonia blended with conventional fuel during the transition
Existing infrastructure leverage — methanol uses existing tank standards with modest modifications · ammonia uses LPG-grade technology already present in most major ports
Natural hydrogen connection — if geological H₂ from Lorraine reaches €0.50/kg from 2028, the production cost of both e-methanol and e-ammonia falls toward fossil parity — removing the green premium that currently requires ETS support
