Ammonia Bunkering Takes Off: How a Western Australia Pilot Could Reshape Global Shipping
The shipping industry, responsible for roughly 3% of global carbon emissions, is facing unprecedented pressure to decarbonize. While alternative fuels like methanol and hydrogen garner attention, a quiet revolution is building around ammonia. A recent milestone – the first ship-to-ship (STS) transfer of ammonia at anchorage in Western Australia, spearheaded by Yara Clean Ammonia (YCA) in partnership with the Global Centre for Maritime Decarbonisation (GCMD) and Pilbara Port Authority (PPA) – isn’t just a technical achievement; it’s a signal that ammonia is rapidly transitioning from a promising concept to a practical reality for zero-emission shipping.
The Western Australia Pilot: A Blueprint for Scalability
The successful trial, conducted within the Port Dampier anchorage area, meticulously simulated real-world bunkering operations. This wasn’t a lab experiment; it was a demonstration of ammonia transfer safety and efficiency under conditions mirroring those faced by commercial vessels. Yara Clean Ammonia’s involvement was pivotal, extending beyond simply supplying the ammonia and chartering the gas carrier Green Pioneer of MOL. The company leveraged its deep expertise in ammonia handling, contributing to critical safety studies, risk assessments, and emergency response planning. As Murali Srinivasan, SVP Commercial at Yara Clean Ammonia, stated, the trial proves that with robust safeguards, ammonia bunkering is “feasible but practical.”
This builds upon earlier safety studies conducted by GCMD in Singapore, further solidifying confidence in ammonia as a viable marine fuel. The ability to perform STS transfers – refueling ships while at sea – is crucial for widespread adoption, as it avoids the need for extensive port infrastructure modifications. It’s a logistical game-changer, potentially unlocking ammonia bunkering in locations where land-based facilities are not yet available.
Yara’s Pilbara Advantage: Building an Ammonia Ecosystem
Yara International’s strategic presence in the Pilbara region of Western Australia isn’t coincidental. The company operates a substantial 850,000 metric ton per annum ammonia plant in Karratha, with a significant portion of its output already flowing through Port Dampier. This existing infrastructure provides a crucial foundation for developing a complete zero-emission ammonia supply chain.
Looking ahead, Yara is actively pursuing Project Yuria, a renewable ammonia project slated to begin operations in 2026. This initiative, alongside explorations of additional low-emission ammonia production at its Yara Pilbara Fertilisers (YPF) site, demonstrates a clear commitment to scaling up sustainable ammonia production. As Tessa Major, VP Infrastructure Development & Demand Aggregation at Yara Clean Ammonia, emphasizes, the company isn’t just a supplier; it’s actively “shaping the standards and infrastructure” for global maritime decarbonization.
Beyond Shipping: The Expanding Role of Clean Ammonia
While the immediate focus is on maritime applications, the potential of clean ammonia extends far beyond shipping. Ammonia is increasingly recognized as a key enabler of the hydrogen economy, offering a more efficient and cost-effective means of hydrogen transport and storage. It can be used in power generation, low-carbon food production, and various industrial applications. This versatility positions Yara Clean Ammonia for significant growth, as evidenced by its FY 2024 revenues of USD 1.8 billion and EBITDA of USD 117 million.
Navigating the Challenges: Safety and Infrastructure
Despite the momentum, challenges remain. Ammonia is a toxic and corrosive substance, requiring stringent safety protocols and specialized handling equipment. The GCMD’s ongoing research and the learnings from trials like the one in Western Australia are vital for developing best practices and mitigating risks. Furthermore, significant investment in bunkering infrastructure – including specialized vessels, storage facilities, and transfer systems – will be necessary to support widespread ammonia adoption. The International Maritime Organization (IMO) is actively working on regulations to govern the safe use of ammonia as a marine fuel, a process that will require close collaboration between industry stakeholders and regulatory bodies.

The Future of Ammonia Bunkering: Regional Hubs and Global Standards
The Pilbara region is poised to become a key hub for ammonia bunkering, leveraging Yara’s existing infrastructure and planned renewable ammonia production. However, similar hubs are likely to emerge in other strategic locations around the world, particularly those with access to renewable energy sources and established port facilities. The development of standardized procedures for ammonia transfer, storage, and handling will be crucial for ensuring safety and interoperability across different regions. Expect to see increased collaboration between companies like Yara Clean Ammonia, research institutions like GCMD, and port authorities globally to accelerate the development and deployment of these standards.
The success in Western Australia isn’t just about proving ammonia bunkering is possible; it’s about demonstrating a pathway to a cleaner, more sustainable future for the shipping industry. The momentum is building, and the next few years will be critical in shaping the role of ammonia in the global energy transition.
