Australian company focused on meeting the rising demand for low-emission ammonia in the thriving Asian market.

WAH2 – Low Emissions Ammonia

The energy transition is driving an increasing global demand for low-emissions energy.

Through its WAH2 Project, Hexagon intends to supply low-emissions ammonia to the decarbonising powerhouse economies of the Asia-Pacific, leveraging ammonia’s advantages as a hydrogen carrier and its direct use in clean power generation.

Background to the WAH2 low-emissions ammonia project

In May 2023 the Western Australian Government approved allocation of land for WAH2 in the preferred location in the Maitland Strategic Industrial Area (SIA) proximal to existing services, an existing infrastructure corridor and established export routes.

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 to produce low-carbon ammonia (NH3) for export via the Port of Dampier.

In August 2023, Hexagon announced the completion of the WAH2 Pre-Feasibility Study and based on the encouraging results commenced Pre-FEED studies. Technical activities are being led by Petrofac Asset Solutions Australia Ltd (Petrofac) as lead engineer and Topsoe A/S (Topsoe) as technology provider.

The Pre-FEED studies and ongoing commercial discussions with potential partners are intended to support FEED entry in mid-2024.
