Classification society DNV on Tuesday (11 October) said its Maritime Forecast to 2050 report has utilised an enhanced GHG Pathway Model to build and run 24 scenarios quantifying trends in the bunker fuel transition ahead for the shipping sector.

“Our 6th Maritime Forecast to 2050 report (the report) uses an enhanced version of our GHG Pathway Model to build and run an updated portfolio of scenarios to explore the fuel transition ahead,” said Eirik Ovrum, Maritime Principal Consultant at DNV and lead author of Maritime Forecast to 2050.

“We show that the future fuel mix is highly dependent on underlying assumptions, notably regarding fuel prices and policy ambitions. Shipowners therefore need transition plans that reflect the uncertain future, and flexible fuel solutions that provide robustness and reduce carbon risk.”

Researchers have applied six “fuel family” variations, simulating the availability of: sustainable biomass to produce biofuels (e.g. bio-MGO); renewable electricity to produce electrofuels (e.g. e-MGO); and fossil fuels with CCS (i.e. “blue” fuels). For each of these three fuel families, we assign a “High” or “Very high” fuel-price advantage to one fuel family over the others on a basis described in the report.

They explore three cost variations for specific bunker fuel types, in which changes in the relative cost differences between fuels within each family are explored (as described fully in the report).

“In most of our scenarios, around 5% of the energy use in 2030 is from carbon-neutral fuels. Under IMO ambitions, this grows to around 20% in 2040, depending on the scenario. In Decarbonization by 2050, the share of carbon-neutral fuels reaches 40% to 50% in 2040,” Ovrum explains.

Some carbon-neutral fuels dominate the 2050 energy mix in at least one scenario, namely bio-MGO and e-MGO, bio-LNG, blue ammonia and e-ammonia, and bio-methanol.

Among carbon-neutral fuels, the share of carbon-neutral drop-in fuels (bio-MGO, e-MGO, bio-LNG, e-LNG) is greater in IMO ambitions scenarios than in Decarbonization by 2050 scenarios.

Collaboration is key to alternative fuels availability

“The initial availability in selected regions has ripple effects beyond their borders, and we have seen this pattern before in the uptake of LNG and batteries in shipping,” recalls Ovrum. “We expect similar effects for other carbon-neutral fuels assigned favourable conditions in the scenario design.”

Driven by procurement requirements from governments, uptake of LNG and batteries was assisted by infrastructure first being developed locally, then nationally, then regionally and globally, adds Ovrum.

It illustrates that the public sector can be an important enabler for phasing in new low-emission technology in shipping, he stressed. “The challenges and opportunities illustrated in our modelling can only be solved by strong alliances among the sector’s stakeholders and with other industries competing for carbon-neutral fuels.”

MPA and MSC ink MoU to support adoption of alternative bunker fuels

The Maritime and Port Authority of Singapore (MPA) on Wednesday (3 June) said it signed a Memorandum of Understanding (MoU) with MSC Mediterranean Shipping Company to strengthen collaboration in maritime decarbonisation, digitalisation, innovation, and manpower development. 

The MoU was signed on 25 May 2026 by Mr Ang Wee Keong, Chief Executive of MPA, and Mr Soren Toft, Chief Executive Officer of MSC.

The MoU underscores the shared commitment of MPA and MSC to foster a sustainable, digital, and future-ready maritime sector, while enhancing MSC’s operational and business activities in Singapore. This year also marks the 30th anniversary of MSC establishing its Asia Regional Office and local office in Singapore.

Under the MoU, MPA and MSC will explore new routes and services to strengthen connectivity, support the adoption of alternative marine fuels such as bio-LNG, and advance technologies to improve vessel energy efficiency and operational performance.

MPA and MSC will also collaborate on maritime digitalisation initiatives to improve operational efficiency, including streamlining vessel arrivals and port operations. 

On manpower development, MSC will support internship and scholarship opportunities through Singapore Maritime Foundation’s Maritime Outreach Network (MaritimeONE) platform, an industry-led tripartite partnership comprising industry, government and institutes of higher learning that aims to raise awareness of the maritime industry and attract quality talent into the maritime sector.

Mr Ang Wee Keong, Chief Executive of MPA, said: “This partnership reflects the strong collaboration between MPA and MSC in driving sustainability and digitalisation in the maritime sector. By working together on decarbonisation, operational efficiency and talent development, we aim to strengthen Maritime Singapore’s position as a trusted and future-ready global maritime hub.”

Mr Soren Toft, Chief Executive Officer of MSC, said: “Singapore is a strategically important hub for MSC and a key gateway to the broader Asia region. As we mark 30 years in Singapore, this MOU reinforces our long-term commitment to strengthening our presence here. MSC and Singapore are closely aligned on the priorities shaping the future of global shipping, and we look forward to deepening this partnership to drive the continued growth and resilience of the maritime industry.”

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.”
