Sumitomo, “K” Line and NYK Line to explore ammonia bunkering vessel in Singapore

Sumitomo Corporation, Kawasaki Kisen Kaisha (“K” LINE) and Nippon Yusen Kabushiki Kaisha on Thursday (23 April) said they have been selected to run a demonstration project to supply ammonia as a marine fuel for vessels in Singapore.

Sumitomo Corporation will serve as the coordinating company. 

The Demonstration Project has been selected for the FY2024 Supplementary Budget Grant for the “Global South Future-Oriented Co-creation Project, funded by the Ministry of Economy, Trade and Industry.

The Demonstration Project is designed to establish the groundwork for the future commercialisation of ammonia as a next-generation clean fuel. 

As part of this initiative, the project partners will conduct a trial supply of ammonia fuel using the ship-to-ship (STS) transfer method, employing a bunkering vessel that complies with the requirements set by the Singapore Government. 

This demonstration project will mark the first demonstration of ammonia bunkering by the collaborators. Through this demonstration, the collaborators aim to develop robust safety standards and refine operational procedures, paving the way for the eventual launch of commercial ammonia bunkering services in Singapore.

At present, around 20 million tonnes of ammonia are being traded globally each year, primarily for use in fertilisers and chemical production. 

Maritime transportation of ammonia has played a central role in this trade, with STS transfers already occurring between ammonia carriers. 

However, the supply and utilisation of ammonia as a maritime fuel for vessels introduce new complexities. Given ammonia’s toxic properties, its use requires strict safety measures, specialised equipment and the development of internationally agreed safety standards and operational guidelines.

As a large-scale initiative, the Demonstration Project will be critical in overcoming the technical and operational challenges that must be addressed before commercial services can be fully realised. 

Meeting safety standards and developing operational guidelines is expected to deliver industry-wide benefits, serving as benchmarks of public interest for the safe adoption of ammonia as a bunker fuel. Given the substantial costs associated with the demonstration phase, the financial support from this grant will be pivotal in ensuring the project’s viability and successful execution.

Singapore is the world’s largest bunkering hub. With its well-developed port infrastructure and operational expertise, the country offers a practical testing environment for the commercialisation of ammonia fuel. 

Through the Demonstration Project, feasibility studies will assess supply facilities while managing operational risks, establishing procedures, and evaluating environmental and safety factors to confirm the viability of safe, sustainable ammonia fuel supply.

Höegh Autoliners orders six more ammonia, methanol-ready Aurora class PCTCs

Höegh Autoliners on Tuesday (22 September) said it has formally signed a contract with China Merchants Group (CMG) for six additional Aurora class pure car and truck carriers (PCTCs). 

The contract was signed during a high-level meeting in Naples attended by senior representatives from both companies, including Miao Jianmin, Chairman of China Merchants Group. Chair of Höegh Autoliners, Leif O. Høegh, and Andreas Enger, CEO of Höegh Autoliners.

The six additional dual-fuel LNG and zero-carbon-ready vessels will be built by China Merchants Heavy Industry (Jiangsu) Co., Ltd. (CMHI) and delivered between 2029 and 2031. 

With 18 Aurora Class vessels in the programme, Höegh Autoliners is building the fleet needed for a zero- emission future and setting the pace for the transformation of deep-sea shipping.

The Aurora Class vessels can carry up to 9,100 cars and reduce carbon emissions per transported car by up to 58 per cent compared with conventional PCTCs. They have DNV’s ammonia-ready and methanol-ready notations and are designed to be converted to run on future zero-carbon fuels.

Leif O. Høegh, Chair of the Board of Directors of Höegh Autoliners, said: “For nearly 100 years, we have developed, adapted and led the way through major changes in shipping. It is in our DNA to keep moving and challenge what is possible. This signing continues that story. We are investing in the vessels that will define our fleet for decades and help move our industry towards zero emissions.”

Andreas Enger, CEO of Höegh Autoliners, said: “This is not just another vessel-building agreement. It is a statement about the future of deep-sea shipping and the role we intend to play in shaping it. The Aurora Class is at the heart of our fleet renewal and our path to a sustainable future. By expanding the programme to 18 vessels, we are securing efficient, flexible and future-ready capacity while setting the pace towards zero-emission operations.”

Miao Jianmin, Chairman of China Merchants Group, said: “Höegh Autoliners is a pioneer in international shipping and will celebrate its 100th anniversary next year. We would like to offer our congratulations in advance! Over the past century, Höegh Autoliners has achieved remarkable development and has grown into a leading company in the global RoRo shipping sector. We truly admire what you have accomplished.”

GCMD, Equinor to combine expertise on alternative bunker fuels, decarbonisation solutions

The Global Centre for Maritime Decarbonisation (GCMD) and Equinor on Tuesday (22 September) announced a five-year Impact partnership.

The partnership brings together GCMD’s capabilities in conducting real-world maritime pilots with Equinor’s experience as a charterer, energy provider and developer of low-carbon solutions.

Together, the organisations will leverage their complementary expertise to help address technical and operational gaps in scaling alternative marine fuels and supporting the development and uptake of other maritime decarbonisation solutions.

GCMD’s work on alternative fuels, including biofuels, ammonia and methanol, focuses on two critical aspects of deployment: operational safety and robust monitoring, reporting and verification (MRV). Its pilots and studies are generating operational data to support safe bunkering and handling of these fuels. 

At the same time, its assurance work seeks to strengthen confidence in quantity, quality and GHG emissions abatement.

“Equinor brings extensive experience as a vessel charterer and marine fuel supplier. This includes chartering dual-fuel LNG, LPG and methanol tankers, testing and using biofuels and supplying methanol to the maritime sector,” GCMD said.

Equinor is also piloting the use and supply of ammonia as a marine fuel, contributing to the development of associated safety, regulatory and bunkering arrangements.

Combining these perspectives can help address practical barriers to alternative fuels deployment while strengthening assurance across emerging marine fuel value chains.

Beyond alternative fuels, GCMD is working to accelerate the adoption of solutions that can reduce emissions from the existing fleet, including energy efficiency technologies (EETs) and onboard carbon capture and storage (OCCS).

GCMD’s work on EETs includes quantifying real-world fuel savings from technologies such as wind-assisted propulsion systems and developing financing mechanisms to scale their adoption. In OCCS, Project CAPTURED demonstrated an end-to-end value chain for onboard captured and liquefied CO₂, generating evidence that contributed to the recognition of captured CO2 under the EU ETS and in-principle support at the IMO for recognising carbon mineralisation as permanent storage.

Equinor brings decades of experience in offshore CO₂ storage, including its role in the development and operation of Northern Lights, the world’s first cross-border CO2 transport and storage facility, where liquefied CO₂ is transported by ship to an onshore receiving terminal before it is sent by pipeline for permanent geological storage beneath the North Sea.

Through the partnership, GCMD and Equinor will explore opportunities to combine their respective capabilities and experience to support the deployment and scaling of maritime decarbonisation solutions.

The International Maritime Organization on Tuesday (22 September) said international experts have shared their insight on the use of ammonia as marine fuel during an IMO technical seminar at IMO Headquarters in London (17 September). 

The seminar was organized by IMO’s Future Fuels and Technology Project (FFT Project) and brought together around 800 participants from IMO Member States, NGOs, IGOs, industry and academia, both in person and online. 

Professor Lynn Loo, Chief Executive Officer of the Global Centre for Maritime Decarbonization, moderated the event. 

Participants exchanged technical information and experiences on the potential use of ammonia as a marine fuel, including developments in production, bunkering and infrastructure, technology developments, notably on ammonia-fuelled engines and control of emissions, as well as safety and environmental considerations. 

Opening the seminar, David Osborn, Director of the IMO Marine Environment Division, highlighted the importance of technical knowledge in supporting discussions on alternative fuels.

“Sound policy must nevertheless rest on sound evidence. The decisions this Organization takes on alternative fuels depend on a clear and shared understanding of what the technology can do today, where the difficulties lie, and what remains unresolved,” he said. 

IMO’s Future Fuels and Technology Project (FFT Project) is a partnership between the Government of the Republic of Korea and IMO, aiming to support GHG emissions reduction from international shipping by promoting the uptake of future fuels and technology. 

The seminar was the fifth technical seminar organized under the project, following previous editions covering onboard carbon capture and storage (OCCS), energy transition of shipping (Hong Kong Maritime week), biofuels and methane-based fuels
