The southern coast of Western Australia has been proposed as the site for the world’s biggest renewable energy hub. It will comprise 50 GW of wind and solar capacity to create millions of tonnes of green hydrogen for use in Australia and for export. The $100 billion Western Green Energy Hub will be one of Australia’s biggest ever projects, and the hub will be comparable in size to the country’s main grid as it currently stands.
The Western Green Energy Hub would cover around 15 000 square kilometres and produce up to 3.5 million tonnes of green hydrogen annually.
The consortium said that the area featured a strong wind resource, with an average speed of 9 m/s, and good solar, with around 2000 kWh per square metre of solar irradiation. That translates into an estimated capacity factor of around 70 per cent. A final investment decision is expected in 2028. CWP and Intercontinental expect the green hydrogen sector to become a $2.5 trillion market by 2050.
