ENGINE on Fuel Switch Snapshot: B100 swings to discount to LBM with high-methane slip

Once a week, bunker intelligence platform ENGINE will publish a snapshot of alternative and conventional bunker fuel prices in the world’s two biggest bunkering hubs. The following is the latest snapshot:

23 March 2026

  • B100 flips to a discount to LBM for Otto MS engines
  • Rotterdam B100’s discount to LSMGO crosses $800/mt
  • LNG-LBM spread in Rotterdam narrows for third week

Rotterdam’s B100 has switched to a discount to 0 gCO2e liquefied biomethane (LBM) consumed in Otto medium speed (Otto MS) engines for the first time since December.

LBM’s high FuelEU Maritime pooling value has significantly reduced its effective cost since the regulation was implemented last year. This made it the most attractive compliance option for dual-fuel vessels in Rotterdam, regardless of whether these vessels had Otto MS or diesel slow speed (diesel SS) engines.

B100 has been at a consistent premium over LBM burnt in Otto MS engines from December until this week. One of the reasons for B100 costs falling relative to LBM has been a lower estimated FuelEU Maritime pooling value for both fuels. LBM generates a greater FuelEU compliance surplus and has taken the biggest absolute hit from a lower surplus price.

LBM’s estimated FuelEU Maritime pooling value was $940-1,100/mt at the start of December and has now dropped by $80-90/mt to $860-1,010/mt. B100’s estimated pooling value has dropped by a smaller $60/mt to $620/mt.

B100-LBM spreads have narrowed significantly over the past month, especially for for vessels burning LBM in high-methane-slip Otto MS engines. A sharp rise in LBM prices has contributed to flip LBM consumed in an Otto MS engine to a $76/mt premium over B100.

Rotterdam’s LBM retains an edge for vessels with diesel SS engines, but its discount to B100 has narrowed by $114/mt on the week to $125/mt.

It should be noted that B100 and LBM largely cater to different vessel segments with distinct operational needs and fuel requirements, and do not necessarily compete with each other.

Rotterdam B100’s discount to LSMGO has widened by $204/mt to $832/mt in the past week. Its discounts to LNG have expanded by $72–74/mt, to $231–427/mt, depending on LNG engine.

Liquid fuels

Rotterdam’s HSFO and VLSFO prices have risen by $28-48/mt over the past week. A $74/mt rally in front-month ICE Brent futures has added upward pressure, while improved bunker fuel availability in the ARA hub could have capped sharper gains.

LSMGO has surged $244/mt higher, largely tracking a $274/mt jump in ICE low-sulphur gasoil futures.

Rotterdam’s B100 benchmark has gained $40/mt. Counter-pressure has come from an €11/mtCO2e increase in Dutch ZRE A ticket prices, which are now at €137–139/mtCO2e.

In contrast, Singapore’s conventional bunker fuel prices have declined by $19-153/mt, while its B100 benchmark has edged $3/mt lower.

B100’s premium over VLSFO in Singapore has widened by $150/mt, while its discount to LSMGO has narrowed by $17/mt.

Liquid gases

Rotterdam’s LNG bunker prices have climbed $111–114/mt higher, depending on methane slip. They have been supported by a 16% rise in the assessed LNG bunker premium, from $136/mt to $157/mt. Prices have been further underpinned by a sharp 14% gain in the front-month Dutch TTF natural gas contract.

Higher withdrawals from underground gas storage and growing fears of prolonged global LNG supply disruptions following damage to Qatar’s Ras Laffan gas field have pushed TTF upwards.

“The impact [of Ras Laffan damage] is likely to be long term, with restoration of production expected to take more than three years,” ANZ Bank senior commodity strategist Daniel Hynes said.

Rotterdam’s LBM price has surged $150–153/mt higher over the past week.

LNG’s premiums over LBM in Rotterdam have narrowed for a third consecutive week, falling by $39/mt to $351–356/mt, depending on engine type.

The Gulf war has also lifted the front-month NYMEX Japan/Korea Marker (JKM), which has helped to push Singapore’s LNG bunker prices up by $233–234/mt in the past week, also depending on engine type.

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.”
