The Western Green Energy Hub is a proposal to design, construct and operate a large-scale wind and solar power project for green ammonia production. The proposal is located within a 2,269,015 hectare development envelope extending from the far southeast of Western Australia in the Shire of Dundas and City of Kalgoorlie-Boulder, to the northwest of Eucla in the South Coast Region. The coastal and offshore components comprise a marine offloading facility, desalination plant, brine pipeline and an ammonia (or other vector) export pipeline, set within State Waters only, requiring 198 hectares of permanent seabed clearance.
Given the scale of impact from a potential ammonia spill, as well as the effects of desalination and other associated marine infrastructure associated with this project on south coast commercial fisheries and the marine environment, WAFICs preferred option for decision by EPA is Assess – PER, which is the most extensive review option. The EPA has determined the proposal requires a PER, which aligned with WAFICs submission.
