Key Market Drivers

Global Maritime Trade Growth: The Volume Foundation

The fundamental driver of bunker fuel volume growth is the expansion of global seaborne trade. Approximately 90% of the world's merchandise trade moves by sea, a proportion that has been remarkably stable over decades, and as global GDP grows, trade volumes increase, requiring more vessel voyages and greater fuel consumption. The growth of containerized trade driven by global supply chains, the expansion of LNG shipping as countries diversify energy supply away from Russian pipeline gas, the growth of agricultural commodity trade connecting production surpluses in the Americas with consumption deficits in Asia and Africa, and the expansion of e-commerce generating growing demand for fast container services are all structural drivers of vessel fuel consumption.

IMO Regulatory Framework: From Sulfur Cap to Carbon Intensity

The regulatory framework administered by the International Maritime Organization is the most powerful structural force reshaping the composition, if not the absolute volume, of the global bunker fuel market. The IMO 2020 sulfur cap, which reduced the global sulfur limit in marine fuel from 3.5% to 0.50%, permanently shifted demand from HSFO to VLSFO and MGO for non-scrubber-equipped vessels, and drove significant investment in exhaust gas cleaning systems that allow continued HSFO consumption with sulfur-equivalent compliance. VLSFO now accounts for approximately 43 to 53% of the global bunker fuel market by volume, having become the standard marine fuel of reference for the world's non-scrubber fleet.

The IMO Carbon Intensity Indicator (CII) framework, which entered its operational phase in 2023 and is tightening annual reduction targets through 2026, is the next major regulatory driver reshaping bunker fuel demand patterns. CII rates vessels on an annual A to E scale based on CO2 emissions per unit of transport work, and requires ships rated D for three consecutive years or E for a single year to submit corrective action plans demonstrating a path to a C rating or above. In 2026, the CII framework has evolved from a compliance exercise into a core commercial and financial performance driver: CII ratings now influence vessel chartering decisions, freight rates, port state inspection priorities, and asset valuations, creating powerful economic incentives for operators to switch to lower-carbon fuels, reduce vessel speeds, or retrofit vessels with energy efficiency technologies.

LNG Bunkering: The Leading Alternative Fuel Transition

LNG is the leading alternative marine fuel by volume, with established bunkering infrastructure at major global ports and a growing fleet of LNG dual-fuel vessels. LNG reduces SOx emissions by virtually 100%, NOx by up to 85%, and CO2 by approximately 20% compared to conventional VLSFO on a tank-to-wake basis. The CII framework's CO2 intensity calculation creates commercial advantage for LNG-powered vessels over conventional fuel oil vessels at equivalent operational profiles.

Major oil and gas companies are investing significantly in LNG bunkering infrastructure. BP acquired a 40% stake in a Singapore LNG supplier, adding two 10,000 cubic meter LNG bunkering barges to its fleet. TotalEnergies and ADNOC are pooling resources to develop floating LNG storage in Fujairah, extending Gulf LNG bunkering capability into Asia-bound shipping lanes. Singapore's LNG bunker sales reached 571,000 tonnes in 2025, up 23.9% year-on-year, reflecting accelerating uptake as more dual-fuel capable vessels enter commercial service.

Green Methanol: The Emerging Low-Carbon Alternative

Green methanol produced from renewable energy and sustainable feedstocks, including agricultural waste, municipal solid waste, and captured CO2, is emerging as a commercially viable zero-carbon marine fuel candidate with particular appeal to container shipping lines, including CMA CGM, Maersk, and COSCO, that have made public decarbonization commitments. Methanol is liquid at ambient conditions, can be stored in conventional tanks with modest modifications, and has a growing bunkering supply chain at key ports.

In March 2025, CMA CGM partnered with Preem to secure 50,000 tonnes of renewable methanol annually from 2026. In September 2025, Methanex, the world's largest methanol producer, launched commercial bunkering operations in the ARA region through Tank Match and in South Korea through Alpha Maritime. In February 2026, the United Kingdom's first commercial biomethanol bunkering service was launched at the Port of Immingham through a partnership between Exolum, Methanex, and Orsted. The Port of Singapore awarded three new methanol bunkering licences effective January 1, 2026, and the first Singapore methanol bunkering operation was completed on January 20, 2026, on the Singapore-flagged Brave Pioneer by Golden Island Pte. Singapore's methanol bunker sales grew 87.5% in 2025, though from a very small base of just 3,000 tonnes, indicating the category is in its very early commercial stages.

The global fleet of methanol-capable vessels is expected to grow from approximately 106 to 112 in early 2026, with nearly 300 methanol- or ammonia-capable vessels on order globally as of late 2024, signaling the pace at which the shipping industry is preparing for alternative fuel-capable operations.

Ammonia: The Long-Term Zero-Carbon Candidate

Green ammonia produced by combining green hydrogen with nitrogen using renewable energy is theoretically one of the most compelling long-term zero-carbon marine fuels due to its high energy density per unit weight and the global availability of nitrogen as a feedstock. However, ammonia bunkering is currently at an earlier developmental stage than LNG or methanol, with no commercial ammonia bunkering operations yet established and significant technical, safety, and infrastructure challenges to overcome before commercial-scale deployment.

Shell and the Port of Rotterdam announced a EUR 120 million commitment to develop an ammonia bunkering terminal at Rotterdam, targeting a 2028 operational start-up the most significant announced investment in ammonia bunkering infrastructure to date. In Singapore, the Maritime and Port Authority (MPA) is preparing to publish the world's first Technical Reference standard for ammonia bunkering operations during Q2 2026, a regulatory milestone that will provide the safety and operational framework necessary for commercial ammonia bunkering to begin at the world's largest bunkering port.

Mitsui O.S.K. Lines has ordered two ammonia-fuelled Capesize bulk carriers from Japan Marine United for 2027 delivery, among the first commercial ammonia-capable vessels ordered for the dry bulk sector.

Global Bunker Fuel Market Growth

Bunker fuel refers to the fuel used in ships, especially large vessels like tankers and cargo ships, derived from the residue of crude oil distillation. Common types include High Sulfur Fuel Oil (HSFO), Very Low Sulfur Fuel Oil (VLSFO), Marine Gas Oil (MGO), and Liquefied Natural Gas (LNG). Bunker fuels offer several benefits, including cost-effectiveness, with fuels like HSFO being cheaper to produce. Their high energy density allows ships to operate efficiently over vast ocean routes without frequent refuelling.

The bunker fuel demand growth is being fuelled by the increased development of hydrogen resources in offshore areas. Additionally, the rising need for bunker fuel in product tankers and crude oil transportation is playing a significant role in expanding the market. Moreover, the growth of marine trade, spurred by heightened import and export activities, is further contributing to this trend.

Global Bunker Fuel Industry Segmentation

Bunker Fuel Market Share

Marine diesel oil (MDO) is becoming a significant driver in the growth of the bunker fuel industry, over high sulfur fuel oil (HSFO) for several key reasons, largely due to regulatory changes and environmental concerns. One of the primary factors boosting MDO’s growth is compliance with the International Maritime Organization’s (IMO) 2020 regulations, which mandate that ships must use fuels with a sulfur content of no more than 0.5%. HSFO, with its higher sulfur content, is restricted in most regions unless ships are fitted with costly scrubber systems to reduce emissions.

Liquefied natural gas (LNG) is increasingly driving demand in the bunker fuel market over very low sulfur fuel oil (VLSFO) due to several key advantages, particularly around environmental benefits and long-term sustainability. One of the most significant factors is LNG’s ability to significantly reduce harmful emissions compared to VLSFO. LNG emits lower levels of sulfur oxides (SOx), nitrogen oxides (NOx), carbon dioxide (CO2), and particulate matter, making it a much cleaner alternative. As the maritime industry faces growing pressure to reduce its environmental impact, LNG provides a better option for meeting both current and future emission regulations.
