A new study commissioned by SEA-LNG has found that liquified bio-methane (bio-LNG) can make a major contribution to maritime decarbonisation.

Conducted by the Maritime Energy and Sustainable Development Centre of Excellence (MESD CoE) at Nanyang Technological University, Singapore (NTU Singapore), the study explored questions around fuel availability, cost, lifecycle emissions and logistics, providing an overview of the applicability of bio-LNG as marine fuel. It also investigated the feasibility of LNG and bio-LNG as a realistic pathway for the shipping industry to achieve greenhouse gas emission reduction targets in a sustainable manner.

Bio-LNG can be blended with fossil LNG in relatively small amounts to reach the 2030 International Maritime Organization targets and the biofuel proportion in the mix can be increased to meet 2050 targets.

The findings suggest that pure bio-LNG could cover up to 3% of the total energy demand for shipping fuels in 2030 and 13% in 2050. If it is considered as a drop-in fuel blended with fossil LNG, bio-LNG could cover up to 16% and 63% of the total energy demand in 2030 and 2050, respectively, assuming a 20% blending ratio. In the long term, shipowners who have invested in the LNG pathway will need to shift to renewable synthetic LNG (e-LNG).

The report also forecasts that the average cost for delivered bio-LNG will fall by 30% by 2050 compared to today’s values, mainly driven by the reduced cost of producing biomethane in large-scale anaerobic digestion plants. This makes bio-LNG one of the cheapest sustainable alternative marine fuels, compared to biomethanol and electro-fuels, including e-ammonia and e-methanol.

Furthermore, the report highlights that the uptake of bio-LNG in shipping will be linked to the widespread use of biomethane across other sectors.  This will require national and international standards for biomethane injection into gas grids, plus a commonly accepted certificates of origin scheme to efficiently trade biomethane in its gaseous and liquefied forms and to minimise transportation costs.

Peter Keller, Chairman, SEA-LNG, said: “The decarbonisation of shipping will require the use of multiple low and zero carbon fuels. Every fuel has its own individual, but similar, pathway to net zero. When assessing decarbonisation options for the maritime sector it is essential that each pathway is properly evaluated, not simply the destination. It is crucial that decision making is guided by accurate information that assesses each alternative fuel pathway on a like-for-like and full life-cycle basis (Well-to-Wake).”

Keller added: “The viability of the LNG pathway depends on the volumes of bio-LNG and e-LNG that become available to the shipping industry, and the cost of these fuels in comparison to other zero or low carbon fuels. This latest study from the Maritime Energy and Sustainable Development Centre of Excellence at Nanyang Technological University, Singapore, confirms that bio-LNG is a solution for the decarbonisation of the shipping sector thanks to the mature and commercially available technologies for fuel production and use on-board, existing delivery infrastructure plus the competitive cost compared to other sustainable biofuels and electro-fuels.”

Associate Professor Jasmine Lam, Centre Director, MESD CoE, NTU Singapore, said: “Our research concludes that bio-LNG, produced from sustainable biomass resources, has the potential to meet a significant proportion of future shipping energy demand. The findings show that bio-LNG is among the cheapest sustainable biofuels and can potentially offer significant cost advantage over electrofuels by 2050.”

Bruno Piga, Research Consultant for MESD CoE, NTU Singapore, added: “Bio-LNG can provide up to 80% greenhouse gas emissions reductions compared to marine diesel if methane leakage in the production process and on-board methane slip are minimised. It can be used as a drop-in fuel in existing LNG-fuelled engines and can also be transported, stored and bunkered in ports using the existing LNG infrastructure. This reduces logistics costs considerably compared with other alternative fuels.”

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.”
