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.

Rotterdam 1Q bunker sales fall sharply
Rotterdam 1Q bunker sales fall sharply
London, 16 April (Argus) — Demand for conventional marine fuels in Rotterdam fell by 28pc on the year in the first quarter of 2026, after the Netherlands implemented the EU's revised Renewable Energy Directive (RED III) at its ports. The decline also reflects disruption linked to the US-Iran war. Market participants reported a drop in Rotterdam bunker demand even before the war, as some shipowners shifted fuelling to neighbouring ports to avoid price premiums created by the Netherlands' unilateral transposition of RED III marine mandates from 1 January. Sales of very-low sulphur fuel oil (VLSFO) fell most sharply, down by 44pc from a year earlier to about 440,000t in the first quarter. High-sulphur fuel oil (HSFO) volumes dropped by 25pc to about 619,000t, while ultra-low sulphur fuel oil (ULSFO) sales fell by 13pc. Marine gasoil (MGO) and marine diesel oil (MDO) demand declined by 8pc on the year to around 361,000t. Some shipowners instead opted to bunker in neighbouring Antwerp, which forms part of the ARA hub and offers lower conventional bunker prices without requiring route changes. Others prioritised bunkering at Gothenburg in Sweden or ports in Germany, market participants said. Price differentials supported the shift. Between early February and the end of March, MGO dob Rotterdam prices averaged $12.75/t higher than the Antwerp equivalent, while VLSFO dob Rotterdam held an average premium of roughly $14.50/t over the same period. Tighter global supply has added further pressure. The effective closure of the strait of Hormuz sharply reduced bunker availability in Singapore, increasing competition for VLSFO and MGO cargoes that would otherwise be exported to the ARA hub. After the start of the US-Iran war, Rotterdam MGO prices rose by 75pc to an average of about $1,186/t in March, while VLSFO prices climbed by 57pc to an average of $710.50/t.

Rotterdam biomarine sales fall in 1Q
Rotterdam biomarine sales fall in 1Q
London, 16 April (Argus) — Marine biodiesel blend sales fell by 35pc in the first quarter compared with the fourth quarter of last year, but were roughly steady compared with the first quarter of 2025. Participants pointed to lacklustre demand in January and February, with an uptick in March as the US-Iran war led to Dutch B100 flipping to a discount against MGO . But these discounts failed to support significant demand growth , as volatility weighed on marine fuel trading activity and buyers hesitant to make significant changes to their procurement strategy based on an acute price spread. Rotterdam's loss has been Singapore's gain. Data from the Port of Singapore showed roughly a 13pc growth in marine biodiesel blend sales on the quarter to the first quarter of 2026. This demand is attributed to FuelEU Maritime requirements, which came into effect in 2025 and require ships coming in, out of, and operating within EU waters to reduce emissions. Shipowners bunkering marine biodiesel in Singapore for EU-bound voyages can use it for FuelEU Maritime compliance. And compliance generated from bunkering marine biodiesel in Singapore can then be used to achieve compliance on vessels operating European routes, via the pooling mechanism, in which obligated companies can combine their compliance balance with other vessels. Bio-LNG sales firmed by 28pc on the quarter in the first quarter of 2026, generating over-compliance which has sold at a significant premium to cost . This may have also weighed on marine biodiesel blend sales, as bio-LNG volumes bunkered would have generated FuelEU compliance surpluses that can then be sold on to vessels that do not have LNG-capable engines. This would then potentially dampen FuelEU-driven demand from those vessels for marine biodiesel blends, and many shipowners did opt to buy surpluses to meet FuelEU requirements. But this dynamic may soon change because of the US-Iran war, where the FuelEU used cooking oil methyl ester (Ucome)–MGO abatement ex-emissions trading system (ETS) price was negative on 7 April. It has since returned to positive levels, marked at €61.45/tCO2e on 15 April. But this remains significantly below FuelEU compliance surplus levels, with offers seen at €175-210/tCO2e, meaning it is currently cheaper to generate compliance using marine biodiesel blends than to buy surpluses to meet the FuelEU requirements.

Multi-fuel most sustainable future for bunkers: Panel
Multi-fuel most sustainable future for bunkers: Panel
Singapore, 16 April (Argus) — Ensuring availability of bunkering options for multiple fuels at key ports is the most viable approach to supporting an energy transition in the shipping industry and the establishment of green shipping corridors between key ports, said participants at the Argus Green Marine Fuels conference in Singapore. The US/Israel-Iran war and the subsequent disruptions to conventional bunker fuel supplies from the Middle East has shown that availability of a wider range of fuels will make shipowners less likely to be caught out by supply disruptions, especially for fossil fuels. The port of Rotterdam is preparing for a multi-fuel future like Singapore, said the port's program manager for sustainable transport Naomi van den Berg. "We see it has having a large part to play in moving towards a sustainable fuels future," she said. But infrastructure at ports must be available to support distribution of alternative fuels such as LNG, methanol and ammonia. Ports in Hong Kong are looking to mainland China for support in supplying alternative fuels, said Amy Chan, deputy secretary for transport and logistics for the Hong Kong Special Administrative Region government. Hong Kong is set to announce a partner for its own shipping green corridor later this year, Chan said. LNG remains by far the fuel of choice, based on order books for vessels . But most shipowners are still opting for dual use or considering triple-use engines to ensure they have the flexibility to refuel at ports that offer the best value fuel. The choice of LNG also means shipowners have the option to switch to bio-LNG. Availability of fuels and pricing remain key concerns, particularly in a challenging market, said Rohit Radhakrishnan, chair of the marine fuels committee in the Singapore Shipping Association. Investment in infrastructure is key to ensuring progress and while there are some existing facilities to support the transition to a multi-fuel future, there are still not sufficient infrastructure to fulfill the shipping industry's needs, said conference participants.

US-Iran war sends FuelEU abatement price negative
US-Iran war sends FuelEU abatement price negative
London, 8 April (Argus) — The FuelEU used cooking oil methyl ester (Ucome)–marine gasoil (MGO) abatement ex-emissions trading system (ETS) price was negative on 7 April, underscoring how the US-Iran war has distorted marine fuel economics by driving fossil fuel prices sharply higher. The abatement price — which reflects the cost of meeting FuelEU requirements by using biodiesel instead of conventional MGO — fell below zero on 2 April for the first time since the assessment began at the start of 2025. It has remained negative since then, standing at -€23.46/t CO2 equivalent (CO2e) on 7 April. It follows a sharp rally in oil markets triggered by the conflict. The front-month Ice gasoil futures contract reached an all-time high of $1,569.75/t on 2 April, lifting MGO values and narrowing the cost gap between fossil fuels and biofuels. As a result, the typical "green premium" associated with biodiesel use was eroded. FuelEU Maritime regulations, which entered into force in 2025, require vessels operating in EU waters to cut greenhouse gas intensity by 2pc. The negative abatement price indicates that, at current values, using Ucome-based marine fuel is cheaper than using MGO on a compliance-adjusted basis. The shift follows an earlier distortion seen during the conflict, when B100 advanced fatty acid methyl ester (Fame) delivered into the Netherlands moved to a discount to MGO delivered into the Amsterdam-Rotterdam-Antwerp (ARA) hub once ETS costs were included. In parallel, traded FuelEU compliance surpluses for 2026 were reported at around €185/tCO2e on 8 April. This means it is currently cheaper to generate compliance using marine biodiesel blends than to buy surpluses to meet the FuelEU requirements. This is in stark contrast to last year, when shipowners largely opted to purchase overcompliance instead of using biodiesel — mainly due to cheaper compliance generated via manure-based bio-LNG . Despite these shifts, physical demand for marine biodiesel has yet to rise meaningfully. Market participants have reported limited increases in buying, but overall demand remains subdued even where biodiesel blends now offer a lower compliance-adjusted cost. This may be because of ongoing price volatility and uncertainty about the direction of the US-Iran war, which is keeping many shipowners focused on securing fossil fuel supplies for their vessels for the coming weeks. Another reason could be a lack of availability of marine biodiesel blends at smaller ports, and concerns from shipowners about engine compatibility for pure biodiesel. Demand for FuelEU compliance surpluses for 2026 has also softened, with plenty of offers but no bids.
