Sembcorp, IHI and GE will explore potential retrofits to existing gas turbines at the Sakra power plant to run on 100% ammonia fuel. The Sakra plant currently features two GE 9FA turbines, which are among the models IHI & GE are targeting for development of a “retrofittable” ammonia combustion system.

Expected to become commercially available in 2025, WinGD’s X-DF-A ammonia powered engines will be fitted on Samsung Heavy Industries’ newbuild vessels. Eastern Pacific Shipping expects its ammonia powered Newcastlemaxes and VLAC fleet to be delivered from 2026 onwards, after signing a series of agreements with MAN Energy Solutions and other key partners.

The Maritime & Port Authority of Singapore and the country’s Energy Market Authority (EMA) have jointly launched an EOI process to build, own and operate low or zero-carbon ammonia power generation and bunkering projects on Jurong Island. A project lifetime of 25 years is stipulated, with operations to begin in 2027 or before.

Since the Clydebank Declaration was signed last December, the prospect of ammonia-fueled, green maritime corridors has been steadily rising. The Global Maritime Forum has just released a valuable discussion paper on potential definitions and approaches for green corridors. Recent announcements in Europe, Singapore, Australia and the Nordic countries demonstrate growing momentum. For maritime stakeholders to capture early learnings and best manage the complex task of alternative maritime fuel scale-up, the opportune time is right now.

The latest episode of Maritime Ammonia Insights webinar centred around collaboration, leadership & Singapore: three critical elements in the maritime ammonia transition. Sofia Furstenberg Stott was joined by Peter H. Kirkeby (MAN Energy Solutions) and Yi Han Ng (Maritime and Port Authority Singapore), who discussed timelines for engine development, the benefits of a consortia approach, and the all-important safety & technical progress of maritime ammonia technologies.

Singapore’s sovereign wealth fund GIC and UK-based Carlyle will both invest in the development of Eneus Energy’s renewable ammonia project pipeline, with plants in the US and UK planned. The Maritime & Port Authority Singapore and Port of Rotterdam have agreed to establish a green maritime corridor by 2027. The agreement will help accelerate the deployment of alternative maritime fuels like ammonia on the critical shipping route, which links two of the world’s largest bunkering ports. And a trio of organisations - PaxOcean Engineering, Hong Lam Marine and Bureau Veritas will jointly develop an ammonia bunkering vessel design.

ABS has granted Approval in Principle to Keppel Offshore & Marine for an ammonia-fueled, ammonia bunkering vessel. The new vessel is a key component of Project Sabre: a high-profile consortium of maritime organisations aiming to commence ammonia bunkering in Singapore by 2030.

Eastern Pacific Shipping will lead development of an ammonia-powered, dual-fuel gas tanker. The carrier will be built by Hyundai Heavy Industries, registered under the Singapore national flag, classed by ABS, and will be the first vessel fitted with MAN Energy Solutions’ G60 two-stroke dual-fuel ammonia engine. As EPS steadily scales up its engagement with maritime ammonia, another high-profile consortium is accelerating a bunkering study in Singapore.

Two recent announcements show Singapore emerging as a center for development of ammonia as a maritime fuel. In both cases, multi-party coalitions, with Singaporean connections, are focusing on ground-breaking work.
