Japan: J-ENG begins co-firing of first full-scale marine engine with ammonia

Japan Engine Corporation (J-ENG) on Monday (21 April) said the first Japanese-developed and manufactured commercial full-scale, low-speed, ammonia-fuelled two-stroke engine has started co-firing operation with ammonia, which will be installed in a vessel.

J-ENG is developing the engine under the “Green Innovation Fund Project: Next-generation Ship Development” of the New Energy and Industrial Technology Development Organization (NEDO).

Since May 2023, when J-ENG started the world’s first ammonia co-firing operation of a large, low-speed, two-stroke engine in a test engine, J-ENG has obtained many results and knowledge, including stable operation at high ammonia co-firing rates and safe handling of ammonia, through various test operations over a period of about a year and a half.

J-ENG will conduct verification operations on the full-scale engine and plans to ship the engine in October of this year. The engine will be installed on an Ammonia-fuelled Medium Gas Carrier (AFMGC) and then demonstration operations of the vessel will be carried out then.

In order to accommodate a wide variety of ammonia-fueled vessels, J-ENG is also concurrently developing an ammonia-fueled engine with a cylinder bore of 60cm, following the first engine with a 50cm cylinder bore mentioned above, for several promising follow-on projects.

Furthermore, after achieving the development and social implementation of these engines, the company has decided to construct a new plant with the support of a subsidy project by the Ministry of the Environment and the Ministry of Land, Infrastructure, Transport and Tourism through the GX Economic Transition Bonds.

The new plant, which is scheduled for completion in 2028, will expand the production of ammonia fuel engines (in the product mix with fuel oil engines) and promote the spread and expansion of zero-emission ships.

“J-ENG, as a first mover of next-generation fuel engines, will contribute to the development of the Japanese shipping and shipbuilding industries through the early launch and expansion of these engines, and at the same time, contribute to the reduction of greenhouse gases (GHG) in international shipping and the achievement of carbon neutrality by 2050,” the company said on its website.

Baleària arranges three LNG bunkering operations on same day in Barcelona

Spanish shipping company Baleària on Thursday (15 May) said it broke an all-time record for the supply of liquefied natural gas (LNG) with the bunkering of three of its vessels in the port of Barcelona.

The occasion marked the first time three bunkering operations were carried out on three different ships on the same day at the same port in Spain.

The company said the three vessels were fuelled with a total of 2,320 MWh of LNG by eight tankers.

Fast ferry Margarita Salas was fuelled by three tankers simultaneously. Ferry Martín i Soler was fuelled by two tankers and ferry Bahama Mama was bunkered by another three tankers also.

“Our commitment to LNG grew by 184% in 2024. Combined with electric propulsion and other eco-efficiency measures, we have managed to reduce our carbon footprint by almost 10% per passenger,” it said.

Cosco-controlled Piraeus Container Terminal offers biofuel bunkering services

Cosco Shipping Europe, the regional management company of China Cosco Shipping Corporation in the European Region, on Friday (16 May) said biofuel bunkering is now available at Piraeus Container Terminal (PCT) in Greece.

PCT, a fully controlled subsidiary of Cosco Shipping Ports, has officially introduced biofuel bunkering services for vessels calling at the Port of Piraeus – supporting customers in achieving greener, more sustainable supply chains.

After listening to customer needs, Cosco Shipping (Europe) said PCT swiftly moved into action to re-evaluate legal foundations for biofuel bunkering under ISO 8217:2024 and new Greek regulations.

It added that PCT also partnered with suppliers to provide full-service bunkering options.

ABS answers critical safety questions related to using ammonia as a marine fuel

ABS engineers examined realistic bunkering situations such as STS, terminal-to-ship and truck-to-ship, as well as ammonia dispersion from the vessel due to a leakage incident in the engine room.

Classification society American Bureau of Shipping (ABS) on Thursday (15 May) published its report to bring together the findings of its advanced research into the performance of ammonia on board.

Critical safety questions such as “how does ammonia behave when it leaks in an engine room?” and “how does a cloud of escaped ammonia disperse during bunkering operations?” are addressed in the latest ABS research.

ABS performed computational fluid dynamics (CFD) simulations using advanced tools to quantitatively assess the risks associated with ammonia dispersion in accidental leakage scenarios.

ABS engineers examined realistic bunkering situations such as ship-to-ship, terminal-to-ship and truck-to-ship, as well as ammonia dispersion from the vessel due to a leakage incident in the engine room.

“This publication provides a comprehensive report of ABS’ efforts to address the challenges and opportunities presented by ammonia as a marine fuel,” said Vassilios Kroustallis, ABS Senior Vice President, Global Business Development.

“Through detailed analysis of ammonia dispersion studies and emergency evacuation protocols, ABS is contributing to the discourse on safe and supportable maritime fuel alternatives, fostering a culture of preparedness and resilience.”

In addition to CFD simulation analysis, ABS leveraged the latest industry best practices and advancements in software and hardware – including acoustic cameras for detecting and visualizing ammonia leakage – to provide a thorough, three-part framework for owners and operators evaluating ammonia as a cleaner fuel source:

Proactive regulatory engagement and risk anticipation
Development and implementation of a multifaceted safety framework, combining qualitative and quantitative risk assessments
Real-time monitoring and optimized emergency response
