Massive project with hydrogen storage in Pilbara.Pilbara renewables hub adds 3GW wind and solar to $20bn planGiles Parkinson 4 May 2018
The consortium behind an ambitious plan to create an Asian Renewable Energy Hub in the Pilbara region of Western Australia have unveiled plans to add another 3GW of wind and solar to the project to help meet domestic as well as international needs.The mooted addition will take the potential cost of the project –which envisages exporting cheap wind and solar to Asian customers via subsea cables – to around $20 billion.The addition of the 3GW of wind and solar will take total generation capacity to around 9GW – with the added capacity targeted at large energy users in the Pilbara, who currently depend on expensive gas and diesel supplies.
The scale of the project is phenomenal. That amount of capacity will generate around 33TWh of wind and solar a year – exactly the amount of wind and solar that is targeted for the whole country by 2020 under the federal renewable energy target.
It would also be the biggest wind-solar hybrid project in the world, could include battery storage, and would likely provide jobs for 3,000 people in the construction phase and 400 people over the long-term operations.
The AREH consortium – which includes global wind turbine manufacturer Vestas, Australia’s CWP Renewables, and Intercontinental Energy – says the extra capacity will allow mine expansions, and the addition of upscale value-added processing.
The 9GW of generation capacity will likely comprise around 6GW of wind generation and 3GW of solar PV generation, and
could also include hydrogen storage facilities for domestic use and export.
The Pilbara is generally known for its excellent solar resources, but CWP says it has also found a major wind resource in the area, and the shift to even larger turbines has dramatically increased its assumed potential.
There is a relatively consistent wind speed of 8.2 metres per second. Transmission losses to Asia are estimated to be about 9 per cent over 3,000km.
Andrew Dickson, from CWP says the consortium found the site –between Broome and Port Hedland – after a 12 month search. “We had a hunch there was good wind. The more we look at it, the more the economics improve,” he told RenewEconomy.
