UK-based classification society Lloyd’s Register (LR) and University Maritime Advisory Services (UMAS) on Monday (20 April) published their latest assessment of the current and future fuels available to shipping to help define the optimum solutions as the maritime industry seeks to reduce greenhouse gas emissions.

Building on research already undertaken by LR and UMAS into Zero-Emission Vessels (ZEVs) and potential transition pathways to decarbonisation, the report is meant to examine the three primary pillars of the adoption of zero-carbon fuels when compared with traditional fossil-based fuels; their readiness from an investment, technology and community perspective.

LR states the study illustrates that regardless of which zero-carbon fuels emerge as favoured options from an economic perspective, from an onboard technology perspective, ZEVs are likely to be technologically possible in the next few years. 

However, for owners and operators to be confident around future investments, the industry will require confidence in the wider community around the fuel supply chain, both in terms of the availability in the quantities required and the land-based infrastructure for production, supply and distribution, it notes.

LR explains the assessment of technology readiness for the various zero-carbon solutions also aims to provide an insight into the current barriers to market uptake, with screening and assessment undertaken on a fuel-agnostic basis, intended to help the industry identify opportunities for new approaches. 

The scope includes onboard procedures for bunkering, on-board storage, processing, conversion and propulsion, it adds.

LR notes the assessment of investment readiness includes an examination of energy source price scenarios, ship-specific case studies, total cost of operation, fuel related voyage costs, impact on cargo carrying capacity and a sensitivity analysis.

It also adds that the third element considers lifecycle emissions and the evolution of the energy landscape in other sectors to provide the context of the wider energy and industrial sectors.

“This paper is the next chapter of our low carbon series, following ‘Zero-Emission Vessels: Transition Pathways’ published in January 2019,” says Katharine Palmer, Lloyd’s Register Global Sustainability Manager. 

“Our work with the Methanol Institute and UMAS is designed to help industry stakeholders to understand the dynamics and interactions between technology, investment and community readiness within the wider range of ship types, sizes and operational profiles.”

“In recognising the scale of the decarbonisation challenge for shipping, there is a need for unbiased, high quality research that presents the alternatives side by side, so that owners can work with all relevant stakeholders to investigate the right solution for their fleets,” adds Chris Chatterton, Chief Operating Officer, The Methanol Institute.

“We’re pleased that this report recognises the role that Methanol has to play in shipping’s transition to a low carbon economy and ultimately as a net zero carbon fuel.”

“This paper highlights the importance of using a holistic approach when assessing the fuel choice for the decarbonisation of the shipping industry and brings together two essential elements: the evolution of fuels production and the implications of their use onboard ships,” adds Carlo Raucci, Principal Consultant, UMAS.  

“The answers to the strategically important question ‘what will be the future fuel for shipping?’ will require further research and analysis, in that regard, this paper provides an important contribution in answering that question.”

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.”
