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 Asian Coal Co-Firing market opportunity is approximately US$10billion pa by 2035.
You can listen to Hexagon’s CEO Stephen Hall talking about the project with Shae Russell in a Cocktails and Commodities podcast released on 22 December 2023 here:
Background to the WAH2 low-emissions ammonia project
In April 2023 Hexagon was allocated a 40ha site in the Maitland Strategic Industrial Area (SIA) in North-Western Australia by the WA State Government.
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.
In August 2023, Hexagon announced the completion of the WAH2 Pre-Feasibility Study and based on the encouraging results commenced Pre-FEED studies.
The Pre-FEED studies and ongoing commercial discussions with potential partners are intended to support FEED entry in mid-2024.
