The WAH2 Project is Hexagon’s flagship project to supply low-emissions ammonia to the decarbonising powerhouse economies of the Asia-Pacific, including Japan and South Korea. The project aligns to Australia’s National Hydrogen Strategy (2019) which set a goal for Australia to be a global hydrogen leader by 2030 and targets the very large Asian Coal Co-Firing market opportunity of approximately US$10billion pa by 2035.
The completed WAH2 Project Pre-Feasibility Study (PFS) demonstrates the technical and financial feasibility of the project and supports Hexagon’s commitment to pre-FEED with a FID target of 2025 and production by 2028. The PFS describes the analysis conducted, risks identified, mitigation strategies and next steps with respect to the project.
Background to the WAH2 low-emissions ammonia project
Hexagon has been allocated a 40ha site in the Maitland Strategic Industrial Area (SIA) in North-Western Australia. This best places the project to deliver competitive, low-carbon, low-risk hydrogen using proven technology to reform natural gas feedstock, carbon capture and storage (CCS) in depleted gas reservoirs, and harness North-Western Australia’s renewable energy potential. WAH2 is the only proposed gas-based project with access to an existing deep-water port and with multiple, mature CCS projects nearby.
The produced hydrogen is proposed to be converted to low-carbon ammonia as the most appropriate energy carrier. This offers reduced processing and transportation costs and greater energy-efficiency than the alternatives of liquid hydrogen or liquid organic hydrogen carriers – and aligns with customers’ need for ammonia.
