Western Green Energy Hub

This project, which would cover the shires of Dundas and the city of Kalgoorlie-Boulder in south-east Western Australia, involves a very large-scale hybrid wind and solar development planned to be built in phases to meet mainly export-related hydrogen/ammonia demand.

Main proponents:

InterContinental Energy, CWP Global, Mirning Traditional Lands Aboriginal Corporation

Main end-use classification:

Export markets main target


Under development

Estimated cost:

Around AUD$100 billion at full capacity (media reports)

Other involvement:


Production details:

Up to 3.5 million tonnes of renewables-based hydrogen or around 20 million tonnes of (renewables-based) ammonia per annum at full capacity


Western Australia, Australia

Project description

The project proponents have announced plans for a very-large hybrid wind and solar development which, when fully operational, could produce up to 50 gigawatts (GW) of renewable-based power over 15,000 square kilometres in south-east Western Australia.

Infrastructure for the planned project would be developed in stages over a 15-year period and at full operations would have the capacity to produce up to 3.5 million tonnes of renewables-based hydrogen or around 20 million tonnes of (renewables-based) ammonia per annum. The planned output would be targeted mainly for the export market as the ‘green fuels’ market expands post-2030, though the project would have the capability to supply domestic end-use markets.

Press reports indicate that first production from the project would be anticipated by 2030 (with the option of constructing an offshore facility to transfer fuels to ships to be evaluated) and at full capacity could cost around AUD$100 billion.

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