Australia's First Green Ammonia Bunkering Fuels Bulk Carrier at Port Hedland

Australia has completed its first green ammonia bunkering of an ammonia-powered bulk carrier, a two-hour ship-to-ship transfer at the Port of Port Hedland that concluded at 8:42 a.m. local time earlier this week.

The 300-meter Mineral Europa, described as the world's first ammonia-powered dry bulk carrier, received certified green ammonia from a bunker vessel before entering port to load iron ore bound for China. CMB.TECH operates the ship; Fortescue charters it.

Fortescue, Pilbara Ports and CMB.TECH announced the operation jointly. They did not disclose the quantity of ammonia transferred.

Why does one bunkering matter?

Port Hedland sits at the heart of the iron ore trade, which depends on large bulk carriers moving Australian exports to Asian steelmakers. Fortescue wants to cut emissions from those voyages by deploying ammonia-powered vessels and building a reliable supply of green marine fuel. A working transfer at a major bulk export port is the proof point the fuel has been missing.

The operation demanded extensive planning. Teams ran vessel compatibility assessments, ammonia dispersion modeling, emergency response procedures and additional marine support. Port authorities cleared the trial only after every safety and operational requirement was met.

Ammonia contains no carbon and produces no carbon dioxide when burned. But its emissions benefits depend on how it is produced and on controlling other pollutants, including nitrous oxide. Its toxicity adds challenges for ship operators, ports and bunker suppliers alike.

What did Fortescue say?

Fortescue Metals CEO Dino Otranto said the operation showed ammonia bunkering moving beyond small-scale testing toward practical use in major commercial ports.

"Industry has moved ahead of regulation to prove the technology," Otranto said.

He added that policy certainty and long-term fuel purchasing commitments are needed to support further investment in green ammonia production and bunkering infrastructure. That is the commercial fault line: the technology works, but the offtake and regulatory framework does not yet exist at scale.

How did Fortescue get here?

The company has backed ammonia as a marine fuel for several years:

• In 2024, its Fortescue Green Pioneer completed ammonia-fueled propulsion trials in Singapore aboard a converted offshore support vessel.
• A ship-to-ship ammonia transfer trial at nearby Dampier in September 2024 established procedures for handling the fuel between vessels.
• Beyond Mineral Europa, Fortescue charters nine other CMB.TECH vessels that can be converted to run on ammonia.
• Earlier this year, the two companies announced an agreement covering up to 12 ammonia-capable bulk carriers.

What happens next at Port Hedland?

Pilbara Ports is studying a clean fuel bunkering hub in the region, and the latest trial is expected to inform future operations. That would give the Pilbara a fueling role to match its export role, supplying ammonia alongside iron ore at one of the world's busiest bulk ports.

Hurdles remain substantial. Fuel cost, availability, safety protocols and regulatory standards all need answers before ammonia becomes routine. The Port Hedland operation shows the fuel can be delivered to large commercial vessels; whether it can be delivered economically depends on the policy commitments Otranto is calling for.
