Project description
After having announced the completion of pre-FEED studies earlier in 2025, in August 2025, NH3 Clean Energy announced that it had entered the Front-end Engineering Design (FEED) stage on its WAH2 Clean Ammonia Project located in Maitland in north-eastern Western Australia in the Pilbara region, with approvals and commercial workstreams formally underway.
(Note: the announcement noted that the engineering component of FEED would commence once the proponent finalises discussions with parties who may participate in the construction, commissioning and / or operation of the project facilities.)
At the completion of pre-FEED studies, the project’s Phase 1 potential clean ammonia production capacity of 650,000 tonnes per annum was noted; such an amount is expected to require sequestration of 900,000 tonnes per annum of carbon dioxide.
The produced ammonia is aimed primarily at the Asian export market.
In its August 2025 announcement, the project proponent indicates a target timing for a final investment decision in late 2026.
The following announcements in support of the development have been made by the project proponent:
- In October 2025, NH3 Clean Energy advised that it has signed a Memorandum of Understanding (MoU) with Mitsui O.S.K. Lines Ltd. and Oceania Marine Energy regarding the development of clean ammonia bunkering operations in the Pilbara region of Western Australia.
- In September 2025, NH3 Clean Energy advised that it has signed a Commitment Agreement with Pilbara Ports Authority regarding the Company’s intended lease of approximately 7.5 hectares a land at the Port of Dampier to support the ammonia loading operations of its planned WAH2 clean ammonia project.
- In June 2025, NH3 Clean Energy advised that it had signed a Memorandum of Understanding (MoU) with the proposed Angel Carbon Capture and Storage Project Joint Venture operated by Woodside Energy Ltd. The non-binding MoU outlines collaboration between the two parties regarding the provision of carbon capture and sequestration services to the planned WAH2 Clean Ammonia Project.
- In December 2024, NH3 Clean Energy advised that it had signed a non-binding MoU with Australian Gas Infrastructure Operations Pty Ltd (AGIO), a subsidiary of Australian Gas Infrastructure Group, regarding the construction of pipelines for the transportation of carbon dioxide from the planned WAH2 Clean Ammonia Project. The pipeline infrastructure would be built, owned and operated by AGIO.
- In November 2024, Hexagon Energy Materials limited (now NH3 Clean Energy) advised that it had agreed to an Indication for the supply of pipeline gas from Chevron Australia Pty Ltd to the planned WAH2 Clean Ammonia Project.
- In May 2024, Hexagon Energy Materials Limited (now NH3 Clean Energy) advised that it had signed a MoU with Oceania Marine Energy Pty Ltd regarding the potential development of a low-emissions ammonia bunkering business at Dampier, in the Pilbara region of Western Australia.
- In March 2024, Hexagon Energy Materials Limited (now NH3 Clean Energy) advised that it has executed a Key Terms Agreement with the Water Corporation of Western Australia, with the intention of confirming a water supply solution for the planned WAH2 Clean Ammonia Project.
- In May 2023, Hexagon Energy Materials Limited (now NH3 Clean Energy) advised that it had received approval from the Western Australian Government for its application concerning the preferred site for the planned WAH2 Clean Ammonia project, with the 40-hectare site located in the Maitland Strategic Industrial Area. The release noted that the applicant would progress discussions with DevelopmentWA to finalise key terms for land tenure.
