NH3 Clean Energy is targeting a final investment decision by the end of 2026 on a project designed to supply low-emissions ammonia to ships and energy customers in Asia. If delivered to schedule, WAH2 could help establish a dedicated ammonia bunkering hub on one of the world’s busiest bulk shipping routes.
Australia’s NH3 Clean Energy is looking to bring ammonia closer to commercial use as a marine fuel, with its proposed WAH2 project targeting first production by the end of 2029, and ammonia bunkering operations from 2030.
The project is intended to supply low-emission ammonia at Western Australia’s Port Hedland and Port of Dampier, positioning the port to serve bulk carriers transporting iron ore from the Pilbara to Asian markets. The route, often referred to as the Iron Corridor, is the world’s largest shipping route by tonnage, and represents a potentially significant market for alternative marine fuels.
Speaking to Platts*, part of S&P Global Energy, NH3 Clean Energy chairman, Charles Whitfield, said the company aims to take a final investment decision (FID) on WAH2 by the end of 2026. The project is designed to serve both maritime demand and the wider energy requirements of the Asia-Pacific region, including Japan and South Korea.
If ammonia-powered vessels become commercially viable, access to fuel at the Australian end of a major bulk trade route could help establish a significant part of the supply infrastructure needed for the route. WAH2’s importance is in its ability to connect production with bunkering services and demand from shipowners.
A potential fuel hub for Australia’s bulk trade
WAH2’s first phase is planned to produce 650,000 tonnes of blue ammonia annually using natural gas feedstock from Western Australia’s North West Shelf. Under Western Australia’s Domestic Gas Policy, NH3 Clean Energy says it can secure gas at a fixed price under long-term arrangements that are linked to inflation, but not to international oil or gas prices. The company says its location alongside the Dampier Bunbury pipeline, which transports gas towards Perth, limits the need for additional infrastructure.
NH3 Clean Energy estimates pre-front-end engineering and design (pre-FEED) costs at approximately $600 per tonne, which Whitfield described as very competitive. Whitfield argues that this provides a degree of cost and supply certainty that could be attractive to prospective customers, particularly amid geopolitical disruption and volatility in global energy markets.
For shipowners, the key consideration is how the price of the delivered fuel, including storage, transport and bunkering, compares with the cost of operating on alternative fuels. The quoted $600/tonne figure is a pre-FEED estimate, not a delivered bunker price.
The project produces blue ammonia from natural gas, combined with carbon capture and storage to reduce CO2 emissions. The ammonia’s well-to-wake carbon intensity will depend on factors including methane leakage, production efficiency and the proportion of process emissions captured. Verified emissions performance will be required to determine its value under the applicable regulatory frameworks.
Building the bunkering chain before the ships arrive
NH3 Clean Energy is developing a range of partnerships that will connect production with port operations and future fuel demand.
In June 2025, the company signed a joint development agreement with Oceania Marine Energy, which will operate an ammonia bunkering vessel, and Pilbara Ports Authority, which manages the Port of Dampier and oversees port safety and bunkering licences. The collaboration is intended to develop the arrangements needed to supply ammonia through ship-to-ship transfers.
NH3 Clean Energy subsequently signed a memorandum of understanding with Mitsui O.S.K. Lines (MOL), building on the existing agreement to support the development of an ammonia hub in the Pilbara by 2030. MOL will initially operate three capesize bulkers jointly with CMB.TECH and is looking to build a fleet of dual-fuelled ships on the West Australia to East Asia route.
A further agreement with Japan’s Itochu Corporation aims to aggregate 300,000t/y of ammonia from the WAH2 project for export, explore financing options and support the project’s FID. The 300,000-tonne annual demand target cited in the Itochu agreement is a material part of the commercial proposition, representing potential demand equivalent to nearly half of WAH2’s planned first-phase production. Converting that prospective demand into firm commitments would help underpin the project’s financing and development.
The Iron Corridor presents an opportunity
The Pilbara–Asia trade could provide a logical starting point for ammonia bunkering because it combines substantial bulk volumes with established, recurring routes between Australian export terminals and Asian customers.
If shipowners introduce ammonia-capable vessels into these trades, dependable fuel supply at Port Hedland or Dampier could support regular operations and help concentrate early demand around a defined corridor. The project’s proximity to major Asian ammonia markets is also central to its appeal, as is that it is source of supply from a geopolitically stable region, without dependence on transshipment through maritime chokepoints. For energy-importing economies concerned about supply disruption, diversification has strategic value. For shipping, security of supply and price stability are equally relevant to managing operating costs and trade resilience.
NH3 Clean Energy expects its ammonia to serve power-generation customers in Japan, South Korea and other Asia-Pacific markets. The co-firing of ammonia and coal could offer some Asian economies a route to lower emissions, while retaining existing coal-fired generation capacity.
While the energy market could help underpin production volumes, it means that marine fuel demand will have to compete for the same product. The allocation of volumes between shipping and power generation will therefore be an important consideration as the project develops.
From project ambition to maritime deployment
WAH2 aims to connect Australia’s large-scale energy resources with a major shipping trade and the Asian markets that dominate its cargo flows. Its proposed production capacity, partnerships and target bunkering date give the project a clear maritime dimension.
If these elements come together, WAH2 could help establish a dedicated ammonia bunkering hub serving a major international bulk trade. For the Iron Corridor, the opportunity is to align fuel production, port infrastructure and vessel deployment around one of the world’s largest shipping flows, creating a potential pathway for Australian ammonia to gain a foothold in deep-sea bulk shipping.
