MOL and Itochu ink deal for Singapore ammonia bunkering demo
Mitsui OSK and Itochu Pioneering Ammonia Bunkering in Singapore

In a groundbreaking move, Mitsui OSK Lines (MOL) has entered into a joint development agreement with trading giant Itochu Corporation to launch the world’s first ship-to-ship ammonia bunkering operations in Singapore. Scheduled for implementation in the latter half of 2027, this initiative aims to utilize MOL’s upcoming ammonia dual-fuel capesize bulkers alongside Itochu’s innovative ammonia bunkering vessel currently being constructed in Japan. This collaboration is crucial for establishing the technical and safety protocols necessary for offshore ammonia fuel transfers, a key step for the adoption of ammonia as a mainstream zero-emission marine fuel.
Innovative Collaboration and Future Plans
The partnership between MOL and Itochu marks a significant advancement in the shipping industry’s shift towards sustainable fuels. MOL is preparing to deploy its cutting-edge fleet of ammonia dual-fuel capesize bulkers, which are designed to operate on this environmentally friendly fuel. Itochu is contributing its 5,000 cubic meter ammonia bunkering vessel, which is set to be completed in Japan. This vessel will be pivotal in demonstrating the viability of ammonia as a safe and efficient marine fuel option.
In addition to their new venture, MOL has already partnered with Belgium’s CMB.TECH to build three ammonia-powered vessels at Qingdao Beihai Shipbuilding in China, with delivery expected between 2026 and 2027. Meanwhile, Itochu has made strides of its own by placing an order for the world’s first purpose-built ammonia bunker vessel at Sasaki Shipbuilding earlier this summer, which will be flagged in Singapore. These developments underline both companies’ commitment to advancing ammonia as a competitive alternative to traditional fuels in maritime operations.
Ammonia’s Role in the Future of Shipping
Ammonia is gaining traction as a leading candidate in the push for alternative fuels in the shipping industry, primarily due to its zero carbon emissions when combusted. This potential is supported by recent milestones, such as the completion of the world’s first green ammonia bunkering operation by Sinobunker, a subsidiary of COSCO, in China last month. Countries like Singapore, Norway, and South Korea are also exploring ammonia bunkering through feasibility studies and initial planning stages, with numerous ammonia-ready vessels currently on order globally. The advancements in ammonia bunkering not only signify a shift toward greener practices but also showcase a collaborative effort among maritime nations to pave the way for a more sustainable future in shipping.
