Global bunker fuel trading company Bunker One is gearing up to test biodiesel blends in marine fuels in Brazil. In an interview with Argus, Bunker One Brazil chief executive Flavio Ribeiro shared his outlook on the opportunity for Brazil to become a global biodiesel supplier for the shipping industry:

What role can biodiesel play in decarbonizing the marine fuel industry?

Brazilian biodiesel could play a relevant role in reducing emissions in the shipping industry. We are major soybean producers and we are the largest exporter. We have the means to produce more biodiesel. While many in the fuel industry argue that biodiesel blends increase costs, we see it differently. With more demand for biodiesel, production will increase. There is untapped potential. We work in an industry that has massive amounts of fuel. One vessel consumes more fuel in a month than the average filling station. The shipping industry is focused on reducing emissions and Brazil has surplus capacity for biodiesel production. As part of the largest conglomerate in this industry in the world, we see potential.

When does Bunker One plan to begin its tests with biodiesel blends?

The test will begin shortly with our Rio barge operations and will be conducted by the Federal University of Rio Grande do Norte state. We have been approached by other companies interested in testing the fuel in their vessels. But we think this is unnecessary, because we are convinced that the results will be positive. Tests have been done in the US and Denmark. ISO (International Standardization Organization) has approved blends of up to 7pc for marine fuel. We are conducting the tests to spark interest in biodiesel blends. The tests will also allow the government and regulatory agencies to create proper regulations.

How could biodiesel contribute to lower emissions in the bunker fuel market?

This is part of our broader global agenda to reduce emissions by 2050. It is important to try new technologies, but biodiesel blends are drop-in. It is possible to use existing engines, which makes it much easier to adopt. Although ISO already allows 7pc biodiesel in marine diesel, there are still regulatory issues that need to be resolved by the IMO (International Maritime Organization). The IMO has certain regulations for NOx emissions from fossil fuels. These regulations need to be adjusted to stipulate a NOx cap for bio-blend and fossil fuels. We are hoping that the Brazilian government will use its role on the IMO board to resolve this issue. Once this resolution is fixed, countries all over the world will be able to certify the bio-blend.

How much demand does Bunker One see for biodiesel bunker-fuel blends?

The potential is at least 8-10mn metric tons per year. That is more biodiesel than Brazil currently produces per year. The potential is massive, even if we stick to the 7pc limit. We are focused on 7pc now, but down the road, we could push for a higher blend.

Would subsidies be necessary to implement a B7 blend? Would a blend result in higher fuel costs?

We believe the government needs to pave the way for this program to develop, but not to subsidize its use. With the blend, biodiesel production would increase, which would help lower prices. Of course, nobody wants to pay more for fuel, but the market is pushing for actions to reduce emissions and this comes at a cost. Companies will need to decide how they are going to cover the costs of lowering emissions.

Is the Brazilian government on board with the biodiesel blend project?

We have presented this to (mines and energy) minister (Bento Albuquerque), to the (hydrocarbons regulator) ANP and to ports regulator Antaq. All of them are on board for this research. We need them to work with the IMO to change the regulations. Even if the ANP creates B7 regulations, it could limit sales, because international ships could be prohibited from using the fuel if it is not regulated by the IMO. As the president of the Brazilian Bunkering Association, I am working to create awareness and to push for regulatory changes.

Would bio-bunker B7 potentially compete with LNG bunkering?

Bio-bunker B7 is a drop-in fuel – it uses the same engine and same tanks. To switch to LNG, ships need new tanks, new engines and new import infrastructure. LNG is an option for some global shipping lines, but for general shipping – where ships go where the freight is – B7 offers more flexibility.

Is Bunker One looking to blend its own 7pc biodiesel, or will it buy the finished 7pc biodiesel from local suppliers?

For this project, we have a special permit to buy B100 from producers and will blend it ourselves. Once the blended product is regulated, this process can be done by fuel distributors. There is a lot of interest from the biodiesel industry to move ahead with this process and many potential suppliers have already contacted us.

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
