Western Green Energy Hub

The Western Green Energy Hub (WGEH) is a proposal to design, construct and operate a large-scale wind and solar power project to produce value added products, with the base case assuming renewables-based hydrogen with ammonia and other e-fuels production. The proposed development is situated in the far southeast of Western Australia in the Shire of Dundas and City of Kalgoorlie-Boulder.

Project description

The project proponents are planning to develop the Western Green Energy Hub as a large-scale hybrid wind and solar energy and renewables-based hydrogen production project in the far southeast of Western Australia, approximately 600 kilometres east of Kalgoorlie. Presently, renewables-based ammonia production is the base case hydrogen vector; this and other e-fuels opportunities are to be further investigated and optimised during the development stages of the project.

The full-scale proposal would be implemented within a development envelope approximately 22,000 square kilometres in size and may generate over 200 TWh of renewable energy per annum, dependent on the mix and size of wind and solar capacities.

Full-scale development proposal – main elements

The main onshore components include:

  • Wind turbines – up to approximately 3,000 wind turbines sited in a nominal grid (separated approximately 1.5-2.5 kilometres apart)
  • Solar Farms – up to approximately 35 solar PV farms and related infrastructure
  • Hydrogen electrolyser system – a suite of centrally-sited electrolysers, data centres, substations, compressors, cooling and storage facilities, etc.
  • Ammonia (or other e-fuels) production and storage facility – e-fuels plants developed as ‘trains’ and/or downstream facilities.

The main coastal and marine elements include a desalination plant, a marine offloading facility and an offshore ammonia and other e-fuels export pipeline to transport the produced e-fuels to an export terminal.

The operational capacities of the full-scale development include renewable power production of approximately 70 GW per annum, hydrogen production of approximately 5.4 million tonnes per annum and ammonia production of approximately 30 million tonnes per annum. Other e-fuel production capacities will depend on technology types still to be considered for the site.

Greater detail on the full-scale development proposal can be found in the WGEH project referral documentation submitted to the Western Australian Environmental Protection Authority (and published by the Authority in November 2024).

Project infrastructure would be developed in stages over a possible construction period of 30 years.

Stage 1 development concept – present planning

Announcements in July 2023 and September 2024 indicate that the WGEH and Korea Electric Power Corporation (KEPCO) have collaborated to support advancement of the project. The project advises that this collaboration continues and has included an introduction to other potential partners in southeast Asia, Europe and Australia with interests in offtake, supply- chain and program delivery.

The project advises that a full feasibility study is shortly to be progressed, which would guide further development work on Stage 1 of the project.

The project proponent has advised that, on present planning, Stage 1 of project development is planned to generate around 8 GW of hybrid wind and solar power, enabling the production of up to 500,000 tonnes per annum of renewables-based hydrogen. Stage 1 planning and technical solutions may alter as further cultural, environmental, planning and engineering matters are reviewed.

The project has advised that Stage 1 FID and financial close is presently scheduled for 2029.

The planned output of the WGEH would be targeted mainly for the export market as ‘e-fuels’ markets expand during the 2030s. As well, the project would have the capability to supply domestic end-use markets.

In December 2021, the Western Australian Government announced the project would receive Lead Agency status from the Department of Jobs, Tourism, Science and Innovation.

In March 2025, the project advised that the project has been granted Major Project Status by the Commonwealth Government and that the project will be assessed as a controlled action under the Environment Protection and Biodiversity Conservation (EPBC) Act.

The project has advised that the Western Australian Environment Protection Authority (EPA) will oversee compliance with a Public Environmental Review (PER) and the Commonwealth, Department of Climate Change, Energy, the Environment and Water (DCCEEW) will oversee an Environmental Impact Statement (EIS). Environmental Scoping Documents (ESD) outline environmental survey requirements for both the state and commonwealth. The state ESD has been formally approved by the EPA and is available from the EPA website –  www.epa.wa.gov.au/proposals/western-green-energy-hub As at early September 2025, the DCCEEW scoping document is under final review.

WGEH is substantially located on WA Mirning traditional lands. The project advises that an Indigenous Land Use Agreement continues to be progressed between the company and WAMirning People Aboriginal Corporation.
