An international consortium has put forward a proposal for the world’s largest renewable energy hub in the south-east of Western Australia.

Covering a 15,000km² area in the Goldfields-Esperance region, the Western Green Energy Hub (WGEH) could generate up to 50GW of wind and solar energy.

Around 30GW from the hub is expected to be produced from wind, with the rest generated by solar power.

Proposed to be built in phases, the WGEH would produce up to 3.5 million tonnes of zero-carbon green hydrogen, or 20 million tonnes of green ammonia, a year. This would be provided to both the domestic market and overseas markets.

The consortium behind the proposal includes InterContinental Energy, CWP Global and Mirning Green Energy, a wholly owned subsidiary of the Mirning Traditional Lands Aboriginal Corporation.

WGEH Board chairman Brendan Hammond said: “The Western Green Energy Hub is historic on two fronts. The first is the scale at which we will be able to deliver green fuels to markets and customers around the world, helping to move us all towards a net-zero future.

“The second, and possibly more important, is the way in which we are working with the Mirning People, the original owners of the land, to create a truly long-term and sustainable multi-generational partnership that delivers enormous socio-economic benefits for the community.”

The Western Australian government is supporting the project, having dedicated more than A$35m ($26.1m) to developing the state’s renewable hydrogen industry.

Hydrogen Industry Minister Alannah MacTiernan said: “The Western Green Energy Hub is a truly massive proposal that would see Western Australia [become] home to one of the world’s largest renewable energy projects.

“This project is a powerful collaboration between the Mirning traditional owners and industry, and would be a transformational opportunity for the community.

“We look forward to continuing to work with the consortium as they develop their detailed studies and move towards an investment decision.”
