Collaboration Further Demonstrates Feasibility of Bunkering Ammonia for Low-Carbon Marine Fue

Trafigura, a market leader in the global commodities industry, in collaboration with CF Industries, the world’s largest producer of ammonia, today announced the completion of the first co-loaded ammonia and propane shipment operation of its kind. In early January, the Green Power Medium Gas Carrier (MGC) completed a single voyage from the US to Europe loaded with ammonia from CF Industries and with liquefied petroleum gas (LPG or propane) in separate tanks.

The co-loaded vessel project was intended in part as a demonstration of capabilities needed for the efficient and economic transport of low-carbon ammonia to supply ports that may not require a full vessel of ammonia. The ability to co-load low-carbon ammonia with LPG is one pathway to supporting the scale up in availability of low emission fuels. Low-carbon ammonia continues to be a leading alternative fuel candidate for applications such as coal co-firing as well as supporting the marine shipping industry transition from heavy fuel oil to alternatives with a lower-carbon intensity.

“We transport LPG and ammonia from the US to Europe on similar ships on a regular basis,” said Patricio Norris, Global Head of Ammonia and LPG for Trafigura. “We can improve the economics for our customers and reduce emissions with fewer voyages by safely co-loading Ammonia and LPG in the same vessel.”

“We appreciate the partnership we have with Trafigura as we take steps together to help prepare for demand growth of low-carbon ammonia and the expected transition of the marine shipping industry to low-carbon ammonia as a fuel,” said Bert Frost, Executive Vice President, Sales, Market Development and Supply Chain, CF Industries. “Ammonia is safely transported around the world by vessels daily, and this voyage reinforces the flexibility we have to serve emerging low-carbon ammonia demand as we innovate shipping methods with industry-leaders such as Trafigura.”

Ammonia was loaded onto the Green Power from CF Industries’ Donaldsonville, Louisiana, manufacturing complex and LPG was loaded into separate tanks of the vessel in Corpus Christi, Texas. Following a review of applicable regulations, permission from the US Coast Guard, a detailed risk assessment and planning with the ports, shipowner and operator Purus and STS company International Fender Providers (IFP), the loadings proceeded.

Strict segregation requirements ensured that any crossover of liquid, condensate or vapour was prevented. After crossing the Atlantic Ocean, the LPG was discharged via a ship-to-ship (STS) operation in the Mediterranean for use in domestic heating and the ammonia was discharged at Tees Port for CF Fertilisers UK.

This shipment follows Trafigura’s first ship-to-ship transfer of ammonia in July 2024 for
CF Industries, demonstrating the safe and efficient transfer of the feasibility of ammonia bunkering in the future as demand grows for the hydrogen-based low carbon fuels that will enable the shipping industry to decarbonise. CF Industries is currently progressing a carbon capture and sequestration (CCS) project at its Donaldsonville facility that will enable it to produce substantial volumes of low-carbon ammonia. The CCS project is expected to start-up in 2025.
