Alternative marine fuels
Overview
The marine fuel sector is decarbonising. International Maritime Organization (IMO) requirements and EU legislation is driving this change alongside consumer demand for low carbon solutions.
These drivers have prompted shipowners to invest in alternative marine fuels including; marine biodiesel, bio-methanol, grey methanol, LNG, ammonia and hydrogen.
Argus provides pricing, insights, and intelligence for the fast-growing alternative marine fuels market with independent news, analysis, and market commentary on emerging changes and trends so you can stay ahead.

IMO GHG pricing falls short on green methanol, ammonia
IMO GHG pricing falls short on green methanol, ammonia
New York, 7 May (Argus) — The International Maritime Organization's (IMO) proposed global greenhouse gas (GHG) pricing mechanism might not drive significant uptake of green methanol and green ammonia by 2035, given current market prices. Despite introducing penalties on high-emission fuels use and tradable surplus credits for low-emission fuels, the mechanism does not sufficiently close the cost gap for green alternatives. Under the system, starting in 2028 ship operators will face a two-tier penalty: $100/t CO₂e for emissions between the base and direct GHG intensity limit, and $380/t CO₂e for those exceeding the looser base limit. These thresholds will tighten annually through 2035. Ship operators can earn tradable credits for overcompliance when their GHG emissions fall below the direct limit. Assuming a surplus CO₂e credit value of $72/t — mirroring April 2025's average EU emissions trading system price — green ammonia would earn about $215/t in surplus credits in 2028 (see chart) . This barely offsets its April spot price of $2,830/t VLSFO equivalent in northwest Europe. Bio-methanol would receive about $175/t in credits, offering minimal relief on its $2,318/t April spot price. Currently, unsubsidized northwest Europe bio-LNG sits mid-range among bunker fuel options under IMO's emissions framework. While more expensive than HSFO, grey LNG, and B30 bioblends, the bio-LNG is cheaper than B100 (pure used cooking oil methyl ester), green ammonia, and bio-methanol. To become cost-competitive with unsubsidized bio-LNG — priced at $1,185/t in April 2025 — green ammonia and bio-methanol prices would need to fall by 57pc and 49pc, respectively, to around $1,220/t VLSFOe and $1,180/t VLSFOe by 2028. Unless green fuel prices drop significantly or fossil fuel prices rise, the IMO's structure alone provides insufficient economic incentive to accelerate green ammonia and bio-methanol adoption at scale.

Bio-bunker sales in Rotterdam down in 1Q
Bio-bunker sales in Rotterdam down in 1Q
London, 23 April (Argus) — Sales of marine biodiesel blends in Rotterdam fell for the third consecutive quarter in January-March as demand shifted east of Suez. Port data for the first quarter of 2025 show marine biodiesel blend sales declined by 12pc compared with the previous three months and by 60pc compared with the same period last year. The decline was underpinned by lower prices in Singapore. B24 dob Singapore — a blend comprising very low sulphur fuel oil (VLSFO) and used cooking oil methyl ester (Ucome) — averaged a $36/t discount against B30 advanced fatty acid methyl ester (Fame) 0 dob ARA in the first quarter, and a $129.74/t discount against B30 Ucome dob ARA. This price dynamic made Singapore an attractive bunker hub for those shipowners opting to use biodiesel blends to help their customers meet sustainability goals. It also attracted demand from shipowners bound by the FuelEU maritime regulations introduced in January this year. The regulations require a reduction in greenhouse gas (GHG) emissions from ships travelling into, out of and within EU waters, but energy consumed from blends bunkered in Singapore can be mass balanced to be fully accounted for under the scope of the rules. A pooling mechanism within the regulations also allows vessels operating on the east-west route to utilise compliance generated from marine biodiesel blends bunkered in Singapore across other ships that operate solely in Europe. While biodiesel bunker sales in Rotterdam fell, biomethanol sales at the port soared almost sixfold in January-March compared with a year earlier. The sharp rise in demand reflects the rollout of FuelEU Maritime , higher mandates in Europe for the use of renewables in transport this year and changes to regulations on the carryover of renewable fuels tickets in Germany and the Netherlands . Sales of conventional bunker fuels in Rotterdam edged up by a more modest 1pc on the quarter and by 7pc on the year. Sales of high-sulphur fuel oil (HSFO) overtook those of very low sulphur fuel oil (VLSFO), reversing the trend of the previous quarter despite the imminent addition of the Mediterranean Sea as an Emission Control Area (ECA). Ships without scrubbers that sail through ECA zones must use fuels with a maximum sulphur content of 0.1pc, such as marine gasoil (MGO) and ultra low sulphur fuiel oil (ULSFO). LNG bunker sales in Rotterdam fell by the 13pc on the quarter in January-March, reflecting a price rally at the Dutch TTF gas hub in late January and early February. The Argus northwest Europe LNG bunker price stood at a two-year high of €64.35/MWh on 6 February. LNG bunker sales were still higher than in the first quarter last year, which likely stems from the introduction of the FuelEU Maritime regulations.

IMO incentive to shape bio-bunker choices: Correction
IMO incentive to shape bio-bunker choices: Correction
Corrects B30 pricing in paragraph 5. New York, 21 April (Argus) — An International Maritime Organization (IMO) proposal for ship owners who exceed emissions reduction targets to earn surplus credits will play a key role in biofuel bunkering options going forward. The price of these credits will help determine whether B30 or B100 becomes the preferred bio-bunker fuel for vessels not powered by LNG or methanol. It will also influence whether biofuel adoption is accelerated or delayed beyond 2032. At the conclusion of its meeting earlier this month the IMO proposed a dual-incentive mechanism to curb marine GHG emissions starting in 2028. The system combines penalties for non-compliance with financial incentives for over-compliance, aiming to shift ship owner behavior through both "stick" and "carrot" measures. As the "carrot", ship owners whose emissions fall below the IMO's stricter compliance target will receive surplus credits, which can be traded on the open market. The "stick" will introduce a two-tier penalty system. If emissions fall between the base and direct GHG emissions tiers, vessel operators will pay a fixed penalty of $100/t CO2-equivalent. Ship owners whose emissions exceed the looser, tier 2, base target will incur a penalty of $380/t CO2e. Both tiers tighten annually through 2035. The overcompliance credits will be traded on the open market. It is unlikely that they will exceed the cost of the tier 2 penalty of $380/t CO2e. Argus modeled two surplus credit price scenarios — $70/t and $250/t CO2e — to assess their impact on bunker fuel economics. Assessments from 10-17 April showed Singapore very low-sulphur fuel oil (VLSFO) at $481/t, Singapore B30 at $740/t, and Chinese used cooking oil methyl ester (Ucome), or B100, at $1,143/t (see charts). If the outright prices remain flat, in both scenarios, VLSFO would incur tier 1 and tier 2 penalties, raising its effective cost to around $563/t in 2028. B30 in both scenarios would receive credits putting its price at $653/t and $715/t respectively. In the high surplus credit scenario, B100 would earn roughly $580/t in credits, bringing its net cost to about $563/t, on par with VLSFO, and more competitive than B30. In the low surplus credit scenario, B100 would earn just $162/t in credits, lowering its cost to approximately $980/t, well above VLSFO. At these spot prices, and $250/t CO2e surplus credit, B100 would remain the cheapest fuel option through 2035. At $70/t CO2e surplus credit, B30 becomes cost-competitive with VLSFO only after 2032. Ultimately, the market value of IMO over-compliance credits will be a major factor in determining the timing and extent of global biofuel adoption in the marine sector.

FincoEnergies joins FuelEU compliance market
FincoEnergies joins FuelEU compliance market
London, 16 April (Argus) — Netherlands-based fuel supplier FincoEnergies has launched a pooling service to help shipowners comply with FuelEU Maritime requirements. The service will enable undercompliant ships to meet their FuelEU requirements by pooling them with vessels that run on marine biodiesel supplied by FincoEnergies' own GoodFuels brand. The pooling service is also based on a partnership with maritime classification organisation Lloyd's Register, the company said. FincoEnergies said it will take the role of "pool organiser". The FuelEU Maritime regulation, which came into effect this year, sets greenhouse gas (GHG) emissions reduction targets of 2pc for vessels travelling in or out of Europe. The reduction jumps to 6pc from 2030 and gradually reaches 80pc by 2050. The pooling mechanism built into FuelEU Maritime allows shipowners to combine vessels to achieve overall compliance across the pool, enabling a system by which compliance can be traded. Argus assessed the values of FuelEU Ucome-MGO abatement and Ucome-VLSFO abatement, prices which can be used as a metric to value compliance, at an average of $302.56/t of CO2 equivalent (CO2e) and $337.46/tCO2e, respectively, so far this year.
