ENGINE team launched a project to map out all the physical bunker suppliers that offer biofuels in ports and investigated what was available in different regions.
As a growing part of the shipping industry is exploring ways to trim its carbon footprint, the ENGINE team reports that biofuels are making waves and finding their way to bunker ports around the world.
We often get asked variants of the question: “Where can we bunker biofuels?”
For every region and port that was enquired about, we had to investigate what was available. As the information accumulated in leaps and bounds, we decided to launch a project to map out all the physical bunker suppliers that offer biofuels in more and more ports.
It’s a moving target, and this is some of what we have uncovered so far.
East of Suez
Biofuels are starting to become more common in Singapore, but so far they have only made up a fraction of the port’s total bunker sales. B24 (24% biofuel) is the standard blend ratio as sea-going bunker barges are restricted to carrying 25% biofuel and as suppliers seek to err on the safe side of that requirement. Prices are often quotes as a premium over very low sulphur fuel oil (VLSFO) and the typical biofuel grade is fatty acid methyl ester (FAME), which is also called biodiesel.
A couple of Chinese bunker suppliers have started offering biofuel blends for delivery in Zhoushan and Guangzhou, and another two have brought them to Hong Kong. As biofuel blends don’t qualify as bonded bunkers in mainland China, in which value added tax (VAT) is waived for VLSFO, it makes less sense for Chinese refiners and blenders to blend them with VAT-exempt VLSFO. The suppliers therefore import finished B24-VLSFO blends from Singapore and other places before they are sold in Chinese ports.
B35-MGO blends are available in Indonesian ports because of a national 35% minimum biofuel blending mandate. But these derive from palm oil and are not sustainable. Palm oil’s close connection to deforestation means they won’t qualify under the International Sustainability and Carbon Certification (ISCC) programme or as renewable fuels towards upcoming European Union (EU) regulations.
In the Middle East there is one major producer and wholesaler of waste-based biofuels. The UAE-based producer has struck supply deals with two physical bunker suppliers in the country, where it collects used cooking oil (UCO) from McDonalds restaurants and other sources. One of the suppliers has so-called ISCC-certification, which requires the biofuel to meet certain sustainability criteria throughout its lifecycle. From a small base, the producer says that bunker demand has doubled in each of the past three years, and that demand is expected to grow exponentially in the years to come.
Europe & Africa
Rotterdam dominates the global biofuel bunkering scene. Around 6% of all of the bunkers sold in the first half of this year was blended with biofuels, and that was down from an even stronger 8% last year. More biofuel trials and regular refuelling of ships have taken place in Rotterdam than in any other port and a greater number of suppliers offer biofuels there.
Local biofuel processing capacity, imports from China and competition between bunker suppliers in a burgeoning biofuel bunker market provide economies of scale in Rotterdam and contribute to keep prices in check.
But perhaps the biggest reason behind its growth is simple. Rotterdam is Dutch, and the Netherlands has generous market mechanisms in place for biofuels sold for bunkering, particularly for advanced waste-based biofuels. In fact, the price incentives have worked too well and pulled biofuel feedstock away from the road fuels market. The road fuels market faces tougher blending mandates, and more biofuels are needed to meet them, the government told ENGINE.
To rebalance the biofuel scales between road and marine, the Dutch government has launched a consultation with a proposal that could effectively halve the biofuel rebate multiplier. This could see Rotterdam’s discount of more than $200/mt to Singapore be slashed to about half that.
Mediterranean bunker suppliers are also starting to catch the biofuel wave. A few suppliers across Gibraltar, Spain, Malta and Italy now offer blends. Some typically need a week or two of lead time to source, blend and deliver the fuel to ships. One supplier has struck a deal with a ferry company that has tested biofuels blended in small ratios on a ferry with the upcoming FuelEU Maritime regulation in mind.
A lack of biofuel demand in South Africa and Mozambique has meant that suppliers have so far held back on bringing it to market. Some are saying they hope to pursue biofuel in the future.
Americas
US biofuel bunkering is struggling to gain traction in the absence of government subsidies. While harbour crafts and road vehicles enjoy subsidies, ocean-going vessels do not. This has meant that comparable B30 biofuel blends have been prohibitively expensive in Houston compared to Rotterdam for example.
Unlike Rotterdam and the rest of the EU’s upcoming CO2 and greenhouse gas (GHG) regulations, there are also no nationwide US environmental regulations to incentivise uptake of biofuel blends by ships. Customer demand will therefore likely come from ship types close to the end consumer, like ferries, cruise ships and container ships.
Some bunker suppliers have already announced readiness or intent to offer. These include California, where local environmental regulations have boosted uptake of 99% renewable diesel (R99), which differs from FAME in that it is not chemically esters. Canada’s Vancouver, the US Gulf Coast, Colombia’s Cartagena and Brazil make up some of the other places with biofuels on offer.
The Panama Canal is likely the biggest bunker area in the Americas, but a joint venture of companies that was previously buoyant about the prospect of building at least one biorefinery and importing biofuels for bunkering and other transport fuel markets has more recently cast doubts about its feasibility. “The issue is feedstock and competing with current subsidies in the US and EU markets that hog and distort [the] price of feedstock,” one of the companies told ENGINE.
Meanwhile, a recent entrant to the US Gulf Coast’s biofuel bunker market has been championing a mass balancing approach. Its pricing is based on the feedstock type, but thanks to mass balance accounting the feedstock purchased does not necessarily need to be the feedstock in the fuel consumed by that buyer’s ship. Blends based on UCO, soybean oil and tallow are current options, and more waste-based biofuel alternatives is expected to follow in the future.
To help shipowners get more clarity around what’s available where, ENGINE will come out with more detailed overviews of biofuel bunker supply by region and port later this year.

BHP and the Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (3 June) said they have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project.
The bio-blend in the BHP and GCMD pilot is being used on a BHP-chartered bulk carrier Berge Lyngor, owned and operated by Berge Bulk, transporting BHP iron ore from Western Australia to China. When run on bio-blend, the vessel has the potential to reduce well-to-wake greenhouse gas emissions by approximately 79 per cent per voyage compared to sailing on very low sulphur fuel oil (VLSFO).
The vessel bunkered in Singapore in early May with a B100 bio-blend comprising 50 percent tallow-derived biodiesel, sourced and supplied by HAMR Energy, and 50 per cent used cooking oil (UCOME) supplied by Mitsui & Co Energy Trading Singapore (METS).
Mitsui also blended the fuel and Dan-Bunkering coordinated and executed the bunkering operation, which was performed by Global Energy’s barge MT Maple.
The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure.
At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance.
Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels.
The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance.
Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess.
The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.
This project is co-funded by the Maritime and Port Authority of Singapore under the Maritime Innovation and Technology Fund (MINT).

NYK starts one-year B100 bio bunker fuel trial on car carrier
In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices.
Japanese shipping firm NYK on Tuesday (2 June) said it has commenced a one-year long-term trial involving the continuous use of 100% biofuel (B100) on an NYK-operated car carrier.
In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices. High-purity biofuels such as B100 are known to be susceptible to degradation from oxygen, light, and heat, raising concerns about the stability of such fuels during long-term use.
In this trial, the biofuel primarily comprises FAME (Fatty Acid Methyl Ester) derived from used cooking oil and similar feedstocks.
The initiative is designed to evaluate the fuel’s effects on the vessel’s equipment and verify operational safety under real-world conditions.
Through this effort, NYK seeks to accumulate technical expertise that will support the broader use of high-purity biofuels and further accelerate efforts to reduce greenhouse gas (GHG) emissions.
NYK has been advancing the use of biofuels through various initiatives. In 2024, the company conducted a trial using biofuel blend B24 and subsequently expanded practical usage to B30. However, the company said there remains limited global experience with the long-term continuous use of B100.
“By collecting long-term operational data through this trial, NYK aims to accumulate valuable technical insights to support both the safe operation of vessels and the wider adoption of high-purity biofuels,” it said.
Biofuel producer Sunoil recently said it successfully converted the barge Birjo II to run on 100% biodiesel (B100), in collaboration with BFT Tanker Logistics.
The company said the conversion of the barge to run on B100 marks an important step toward reducing emissions within inland shipping and demonstrates how existing barges can already contribute to a more sustainable transport sector.
The Birjo II, owned by DK Shipping, is a large barge used for transporting biofuels on Dutch inland waterways. It is primarily used for transporting biodiesel from Sunoil’s production facility in Kampen to its storage locations, while also carrying out direct deliveries to customers.
By transitioning from fossil fuel to B100, the barge can reduce CO₂ emissions by up to 90% while continuing normal operations without replacing the engine itself.
“This makes Birjo II one of the first barges in the world capable of running fully on 100% biodiesel,” the company added.
The barge will be able to be fueled directly from Sunoil’s Kampen location, creating a fully integrated renewable fuel chain from production to transport and end use.
“What makes this project especially valuable for Sunoil is that Birjo II now operates on our own biodiesel while transporting renewable fuels between our locations and customers,” said Jeroen Hovius, Chief Commercial Officer at Sunoil.
“Together with BFT, we are continuing a strong long-term collaboration focused on practical solutions that help make inland shipping more sustainable. At the same time, this project creates a platform for the conversion and rollout of multiple barges operating on B100 across Europe.”
Sunoil said the successful conversion of Birjo II demonstrates that existing inland shipping assets can already be adapted today to significantly reduce emissions.
“It highlights how practical renewable fuel solutions can support a more sustainable future for inland shipping without requiring full vessel replacement,” it added.
