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.”

Seaspan and Hapag-Lloyd complete first of five methanol vessel retrofit

Seaspan Corporation (Seaspan) and Hapag-Lloyd on Wednesday (3 June) announced the successful completion of the first of the five vessel conversions under their methanol retrofit programme with the delivery of Seaspan Yangtze.

From the early SAVER (Seaspan Action for Vessel Energy Reduction) programme to today’s CleanBlue initiative, Seaspan has committed over USD 230 USD million across 86 vessels, executing more than 550 efficiency and retrofit projects.

Following Seaspan Yangtze, the remaining vessels planned for retrofit under the programme are Seaspan Amazon, Seaspan Ganges, Seaspan Thames, and Seaspan Zambezi. Each retrofit is expected to reduce well-to-wake CO₂e emissions by approximately 30,000 to 50,000 metric tonnes per vessel annually when operating on low-carbon methanol, while also extending vessel lifespan and enhancing fuel flexibility.

“Decarbonisation is not just about building the fleet of tomorrow, it is also about unlocking the full potential of the fleet we have today. Retrofitting and upgrades on existing fleets play a practical, immediate, and economical role in accelerating shipping’s decarbonization journey,” said Bing Chen, Chairman, President and CEO of Seaspan. 

“Project SAVER CleanBlue highlights Seaspan’s strong customer partnerships, deep technical expertise, and unique platform integrated with JV partners, such as WattSpan Maritime Technology, in executing complex and large-scale retrofit projects.”

“The successful conversion of the Seaspan Yangtze together with the planned retrofit of its four sister vessels is another important step on our ambitious path towards net-zero fleet operations by 2045,” said Silke Lehmköster, Managing Director, Fleet, Hapag-Lloyd. 

“Together with Seaspan, we are demonstrating that retrofitting existing vessels for low-carbon methanol can be a practical way to reduce emissions in shipping.”

South Korean-led nuclear car carrier design secures LR backing

Classification society Lloyd’s Register (LR) on Tuesday (2 June) said it has teamed up with South Korean shipbuilding, marine services and nuclear research organisations to advance the development of a nuclear‑assisted car carrier concept. 

LR is working with Hyundai Heavy Industries, Korea Shipbuilding & Offshore Engineering (KSOE), Hyundai Glovis, G- Marine Service and the Korea Atomic Energy Research Institute (KAERI) on a joint development project (JDP) exploring an advanced small modular reactor (SMR) installation on a pure car and truck carrier (PCTC). 

The study focused on how a Molten Salt Reactor (MSR) could be physically and operationally integrated into a large vehicle carrier. Work examined the internal arrangement and segregation of the reactor system, shielding requirements, and the impact on cargo deck layout and vehicle capacity, alongside stability and trim implications linked to the reactor’s weight and positioning. 

The partners also assessed propulsion system configuration and power delivery, as well as operational flexibility compared with conventionally fuelled PCTCs, where trade routes and port calls can be tightly constrained. 

A key focus of the project has been safety. LR led hazard identification (HAZID) and preliminary risk assessment work, focusing on containment, onboard safety systems and potential operability constraints tied to nuclear technology at sea. 

The partners will mark the project milestone with an Approval in Principle (AiP) granting ceremony on 2 June at the LR stand during Posidonia 2026. 

Sung-Gu Park, President – North East Asia, Lloyd’s Register, said: “While nuclear propulsion is still at an early stage of development, this project shows the importance of building technical understanding now to support future progress. 

“Establishing feasibility at concept stage is a valuable step forward, particularly in areas such as cargo optimisation, vessel stability and integrated safety design.” 

Hong-Ryeul Ryu, CTO and Senior Executive Vice President at HD HHI, said: “With global environmental regulations becoming increasingly stringent and no definitive net-zero fuel yet available, SMR-powered ships can serve as a highly effective alternative, representing a pioneering next-generation maritime technology capable of complying with GHG emission regulations while allowing lifetime operation without refuelling, and HD HHI will remain at the forefront of sustainable maritime technology development.”
